Modify the lib/ code to include the ability to interact
with systemd. Provide the ability to interact with
systemd's watchdog timer as well.
There is no code here that actually uses this change.

Testing Done:Manual, see ticket
Changed logic when "interface swpxx <vrf foo>" entered so that:
1. it matches when the command is entered without a vrf but the interface already exists in a vrf.
2. If the command is entered with a vrf name that is different than is defined by the kernel, the command is rejected.
3. If the call is made from other than the vty session, believe the new information and update the vrf accordingly.

When a protocol is attempting to connect to the zebra daemon
through it's socket. If the inital attempt fails, give it a

The json keyword was being read incorrectly.
Basically some commands read a variable # of arguments
and in ospf the command values were being placed into
argc and argv. With a variable # of arguments their
existed a possibility that less arguments would be read
from the cli than were being tested for in the command function
handler. This caused core dumps in some situations.
All code to read to decide to use the json keyword has
been centralized through a function and all code
converted to use it, irrelevant if it exhibited the bug

Zebra already knows if an interface is unnumbered or not. This
is communicated to OSPF.
OSPF would only send a NEXTHOP_TYPE_IPV4_ONLINK *if* the path
was unnumbered, which it learns from Zebra.
As such, Have OSPF use the normal NEXTHOP_TYPE_IPV4_IFINDEX
type for unnumbered paths. In Zebra, if the ifindex recieved
is unnumbered then assume that the link is NEXTHOP_FLAG_ONLINK.

Prefix lists were implemented with a simple linear list that is scanned
sequentially. This is, of course, extremely inefficient as it scales by
O(n). This patch adds a trie-ish data structure that allows quickly
descending based on the prefix.
Note that the trie structure used here is designed for real-world use,
hence it uses a relatively crude fixed-size bytewise table instead of
some fancy balancing scheme. It is quite cacheline efficient.
Using real-world routeserver prefix lists, matching against a fulltable
dump:
entries before after factor
9103 63.8s .0124s 5142x
772 4.52s .0101s 445.3x
86 .445s .0098s 45.51x
7 .0379s .0099s 3.834x
2 .0136s .0095s 1.440x
1 .0084s .0095s .879x
This buys CPU with memory. Memory usage on an IXP setup with 100k
prefix list entries is an additional 4 MB on top of the 9.5 MB that it
was before.

The API messages are used by zebra to exchange the interfaces, addresses,
routes and router-id information with its clients. To distinguish which
VRF the information belongs to, a new field "VRF ID" is added in the
message header. And hence the message version is increased to 3.
* The new field "VRF ID" in the message header:
Length (2 bytes)
Marker (1 byte)
Version (1 byte)
VRF ID (2 bytes, newly added)
Command (2 bytes)
- Client side:
- zclient_create_header() adds the VRF ID in the message header.
- zclient_read() extracts and validates the VRF ID from the header,
and passes the VRF ID to the callback functions registered to
the API messages.
- All relative functions are appended with a new parameter "vrf_id",
including all the callback functions.
- "vrf_id" is also added to "struct zapi_ipv4" and "struct zapi_ipv6".
Clients need to correctly set the VRF ID when using the API
functions zapi_ipv4_route() and zapi_ipv6_route().
- Till now all messages sent from a client have the default VRF ID
"0" in the header.
- The HELLO message is special, which is used as the heart-beat of
a client, and has no relation with VRF. The VRF ID in the HELLO
message header will always be 0 and ignored by zebra.
- Zebra side:
- zserv_create_header() adds the VRF ID in the message header.
- zebra_client_read() extracts and validates the VRF ID from the
header, and passes the VRF ID to the functions which process
the received messages.
- All relative functions are appended with a new parameter "vrf_id".
* Suppress the messages in a VRF which a client does not care:
Some clients may not care about the information in the VRF X, and
zebra should not send the messages in the VRF X to those clients.
Extra flags are used to indicate which VRF is registered by a client,
and a new message ZEBRA_VRF_UNREGISTER is introduced to let a client
can unregister a VRF when it does not need any information in that
VRF.
A client sends any message other than ZEBRA_VRF_UNREGISTER in a VRF
will automatically register to that VRF.
- lib/vrf:
A new utility "VRF bit-map" is provided to manage the flags for
VRFs, one bit per VRF ID.
- Use vrf_bitmap_init()/vrf_bitmap_free() to initialize/free a
bit-map;
- Use vrf_bitmap_set()/vrf_bitmap_unset() to set/unset a flag
in the given bit-map, corresponding to the given VRF ID;
- Use vrf_bitmap_check() to test whether the flag, in the given
bit-map and for the given VRF ID, is set.
- Client side:
- In "struct zclient", the following flags are changed from
"u_char" to "vrf_bitmap_t":
redist[ZEBRA_ROUTE_MAX]
default_information
These flags are extended for each VRF, and controlled by the
clients themselves (or with the help of zclient_redistribute()
and zclient_redistribute_default()).
- Zebra side:
- In "struct zserv", the following flags are changed from
"u_char" to "vrf_bitmap_t":
redist[ZEBRA_ROUTE_MAX]
redist_default
ifinfo
ridinfo
These flags are extended for each VRF, as the VRF registration
flags. They are maintained on receiving a ZEBRA_XXX_ADD or
ZEBRA_XXX_DELETE message.
When sending an interface/address/route/router-id message in
a VRF to a client, if the corresponding VRF registration flag
is not set, this message will not be dropped by zebra.
- A new function zread_vrf_unregister() is introduced to process
the new command ZEBRA_VRF_UNREGISTER. All the VRF registration
flags are cleared for the requested VRF.
Those clients, who support only the default VRF, will never receive
a message in a non-default VRF, thanks to the filter in zebra.
* New callback for the event of successful connection to zebra:
- zclient_start() is splitted, keeping only the code of connecting
to zebra.
- Now zclient_init()=>zclient_connect()=>zclient_start() operations
are purely dealing with the connection to zbera.
- Once zebra is successfully connected, at the end of zclient_start(),
a new callback is used to inform the client about connection.
- Till now, in the callback of connect-to-zebra event, all clients
send messages to zebra to request the router-id/interface/routes
information in the default VRF.
Of corse in future the client can do anything it wants in this
callback. For example, it may send requests for both default VRF
and some non-default VRFs.

This patch lets the netlink sockets work per VRF.
* The definition of "struct nlsock" is moved into zebra/rib.h.
* The previous global variables "netlink" and "netlink_cmd" now
become the members of "struct zebra_vrf", and are initialized
in zebra_vrf_alloc().
* All relative functions now work for a specific VRF, by adding
a new parameter which specifies the working VRF, except those
functions in which the VRF ID can be obtained from the interface.
* kernel_init(), interface_list() and route_read() are now also
working per VRF, and moved from main() to zebra_vrf_enable().
* A new function kernel_terminate() is added to release the
netlink sockets. It is called from zebra_vrf_disable().
* Correct VRF ID, instead of the previous VRF_DEFAULT, are now
passed to the functions of processing interfaces or route
entries.

A new API vrf_is_enabled() is defined to check whether a VRF is ready
to use, that is, to allocate resources in that VRF. Currently there's
only one type of resource: socket.
Two new hooks VRF_ENABLE_HOOK/VRF_DISABLE_HOOK are introduced to tell
the user when a VRF gets ready or to be unavailable.
The VRF_ENABLE_HOOK callback is called in the new function vrf_enable(),
which is used to let the VRF be ready to use. Till now, only the default
VRF can be enabled, and we need do nothing to enable the default, except
calling the hook.
The VRF_DISABLE_HOOK callback is called in the new function
vrf_disable(), which is used to let the VRF be unusable. Till now,
it is called only when the VRF is to be deleted.
A new utility vrf_socket() is defined to provide a socket in a given
VRF to the user.
Till now before introducing a way of VRF realization, only the default
VRF is enabled since its birth, and vrf_socket() creates socket for
only the default VRF.
This patch defines the framework of the VRF APIs. The way they serve
the users is:
- vrf_is_enabled() is used to tell the user whether a VRF is usable;
- users are informed by the VRF_ENABLE_HOOK that a VRF gets usable;
they can allocate resources after that;
- users are informed by the VRF_DISABLE_HOOK that a VRF is to be
unavailable, and they must release the resources instantly;
- vrf_socket() is used to provide a socket in a given VRF.

A new member "vrf_id" is added to "struct rib", reflecting the VRF
which it belongs to.
A new parameter "vrf_id" is added to the relative functions where
need, except those:
- which already have the parameter "vrf_id"; or
- which have a parameter in type of "struct rib"; or
- which have a parameter in type of "struct interface".
All incoming routes are set to default VRF.
In fact, all routes in FIB are kept in default VRF. And the logic
is not changed.

Introduce a new command "interface IFNAME vrf N" to configure an
interface in the non-default VRF.
Till now, only zebra uses this command. Other daemons will install
the command when they support multiple VRFs.

An interface belongs to a specific VRF. So move the interface list
into the "struct vrf".
* vrf.c/vrf.h:
- add a new member "struct list *iflist" to the the "struct vrf";
- call if_init() in vrf_new();
- call if_terminate() in vrf_delete();
- add utilities to access the interface list and VRF ID in the
specified VRF.
* if.c/if.h:
- the global "iflist" now only exists for the default VRF;
- the global "if_master" is initialized on the definition;
- in if_create(), the interface is added into the list in the
specified VRF; if the VRF does not exist, create one;
- add parameters to if_init()/if_terminate() so that the
interface list in the VRF can be initialized/destroyed;
- in if_dump_all() scan the interfaces in all the VRFs;
- add a command "show address vrf N" to show addresses in a
specified VRF;
- add a command "show address vrf all" to show addresses in all
VRFs;
- new APIs ifxxx_vrf() are added to access an interface in a
specified VRF.
The old interface APIs (the global variable "iflist" and the API
functions) are not changed to keep the backward compatibility.
The new APIs are used in the daemons which support multiple VRFs
(till now only zebra).

Later, an interface will belong to a specific VRF, and the interface
initialization will be a part of the VRF initialization. So now call
if_init() from vrf_init(), and if_terminate() from vrf_terminate().
Daemons have the according changes:
- if if_init() was called or "iflist" was initialized, now call
vrf_init() instead;
- if if_terminate() was called or "iflist" was destroyed, now call
vrf_terminate() instead.

Later, an interface will belong to a specific VRF. Now we add a
property "vrf_id" to the "struct interface", and keep it as the
default value 0.
This property is shown when displaying interfaces information.
It is also added in some logs.
This is just the preparation to move the interace list into the
"struct vrf". The main logic is not changed.

Previously "struct vrf" is defined locally in zebra. Now it is moved
to be a lib module.
This is the first step to support multi-VRF in quagga. The
implementation is splitted into small patches for the purpose of
easy review.
* lib:
"struct vrf" with basic members is defined in vrf.c. The member
"void *info" is for user data.
Some basic functions are defined in vrf.c for adding/deleting/
looking up a VRF, scanning the VRF table and initializing the
VRF module.
The type "vrf_id_t" is defined specificly for VRF ID.
* zebra:
The previous "struct vrf" is re-defined as "struct zebra_vrf";
and previous "vrf" variables are renamed to "zvrf".
The previous "struct vrf" related functions are removed from
zbera_rib.c. New functions are defined to maintain the new
"struct zebra_vrf".
The names vrf_xxx are reserved for the functions in VRF module.
So:
- the previous vrf_table() are renamed to zebra_vrf_table();
- the previous vrf_static_table() are renamed to
zebra_vrf_static_table().
The main logic is not changed.
BTW: Add a statement to zebra_snmp.c telling that the SNMP is
running only for the MIBs in the default VRF.

The old style mallinfo() function uses an 'int' to
report memory usage data to the program. Unfortunately
modern architectures can chew through 2gb of memory like a
buzz saw hitting some warm butter, especially in the case
of a memory leak or memory fragmentation.
When a daemon uses more than 2gb of memory, just indicate it's
gotten large and we don't know anymore.

Porting of the patch zebra-fix-cmd-type-desc-log.patch from 2.5 branch
Last few Zebra message command types defined were not added to the command type description table used for getting logging strings. This was causing the logs to display "unknown command type" instead of the actual command type. So, added all the missing zebra commands to the command type description table. Also, changed the order of the description table to match with the actual command type definition order.
