This is theoretically not needed if neither DEFUNs nor zlog_* calls are
used, except I'm about to turn it into a build error to catch the cases
where it _is_ necessary. Which is libmgmt_be_nb.la in this case, where
it causes build failures on hppa.

Add a bunch of helper functions to support encoding of SRv6 SIDs in
protobuf.
Specifically,
* `fpm_srv6_sid_format_create`: encode SID format information into a
protobuf `SRv6SIDFormat` structure
* `fpm_srv6_local_sid_*_behavior_create` functions: encode an SRv6 SID
behavior and associated attributes into a protobuf
`Fpm__SRv6LocalSID__*` structure
This is a preliminary commit to support sending SRv6 Local SIDs and VPN
SIDs via protobuf.

Add two optional fields to the AddRoute protobuf message to support
SRv6 VPN use cases:
* `srv6_vpn_sid`: used to associate an SRv6 VPN SID to a route; if
present, the router will steer the traffic that matches the prefix by
encapsulating the payload in an outer IPv6 header where the destination
address is the SRv6 VPN SID provided
* `srv6_encap_source_address`: source Address of outer encapsulating
IPv6 header

SIDs via protobuf.

The files converted in this commit either had some random misspelling or
formatting weirdness that made them escape automated replacement, or
have a particularly "weird" licensing setup (e.g. dual-licensed.)
This also marks a bunch of "public domain" files as SPDX License "NONE".

like the other automake variables, setting `xyz_LDFLAGS` causes
`AM_LDFLAGS` to be ignored for `xyz`. For some reason I had in my mind
that automake doesn't do this for LDFLAGS, but... it does. (Which is
consistent with `_CFLAGS` and co.)
So, all the libraries and modules have been ignoring `AM_LDFLAGS` (which
includes `SAN_FLAGS` too). Set up new `LIB_LDFLAGS` and
`MODULE_LDFLAGS` to handle all of this correctly (and move these bits to
a central location.)

Anything we list in a xxx_SOURCES variable will be included for "make
tags", including filess marked as nodist_xxx_SOURCES. So if we don't
have Protobuf enabled, even though the entire library isn't built, "make
tags" will still try to process these files... which we can't
autogenerate because Protobuf is disabled. Same for gRPC.

BUILT_SOURCES doesn't do what the name suggests. What it actually means
is "these files should be built first when doing a 'make' without
explicit target" (or "make all").
It's pretty much almost always wrong to use BUILT_SOURCES, the only
correct use is when a file is needed by an unspecified / large set of
files.
Also remove version.h and route_types.h from dist tarball while we're at
it. configure will create them anyway.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

FPM aims to provide cross platform mechanism to support the scenario
where the router has forwarding path distinct fromt the kernel.Commonly
Hardware based fast path.Hence it is non-configurable paramter.This
limits us to use funcationality to update FIB information to remote
hosts, like SDN controller.
This implementation provides the CLI to configure remote hosts and port
information of remote fpm controller.Otherwise default fpm server will
be localhost and default fpm port will be well know port 2620.
* zebra_fpm.c: added fpm_server paramter to zfpm_global_t handler.
Implemented CLI for configuring the fpm server and no fpm
command to revert back to default configuration.
* zserv.c: Install zebra node to write fpm configuration info
on console/config file.
Further documentation supplied:
-------------------------------
ZEBRA : CLI CONFIGURATION FOR FPM MODULE
========================================================
1. INTRODUCTION
================================
1.1 scope
This memo discusses the configuration option for zebra to update
FIB information to local and remote modules.
This will also helps to address the issue associated with CORD project.
https://jira.onosproject.org/browse/CORD-411
2. REFERENCE
================================
Quagga version 99.24+ ( main branch committed on 29-sep-2015)
3. PROBLEM DESCRIPTION
================================
Once FPM is enabled, Quagga periodically tries to initiate fpm
connection to localhost:2620. These values are non configurable in
existing implementation. There is no CLI available to configure
"host:port". hence limits us to use it for hardware based fast path
modules only.
4. PROPOSED CHANGES
================================
Following changes are done to the quagga code
a) Added new CLI to configure "host address : port".
The CLI format
<conf t>
$ fpm connection ip <ipv4 address> port <tcp port num>
and no fpm command to revert back to default
<conf t>
$ no fpm connection ip <ipv4 address> port <tcp port num>
b) Allowed values are ipv4 address and tcp port range <1-65535>
c) FPM initialization code has been enhanced to pick the "host
address : port" values from zebra.conf. if not found then
default values as localhost:2620 will be used. and updated the
information on to config file on write config command
5. FILES MODIFIED
================================
1) fpm/fpm.h :
a) Added MACRO to represent network order loopback ip
2) zebra/zebra_fpm.h :
a) introduced fpm_server variable in zfpm_glob_t handler to hold
the remote fpm server address
b) Hooked 'fpm_remote_ip_cmd' and 'no_fpm_remote_ip_cmd' at CONFIG
node to configure remote fpm detail and to revert back to
default respectively
3) zebra/zserv.c :
a) Hooked 'config_write_fpm' callback function, at ZEBRA_NODE to
display the fpm connection details on console on entering
command
$ show running_config
and to write to configuration file on entering command
$ write config
6. TESTING DETAILS
================================
6.1. default behavior
In default configuration FPM will attempt to connect to
localhost:2620
6.2. update fpm info
a) Using CLI command user can configure fpm host:port details
and can be able to write to config file(zebra.conf) using
write config command. this parameters has no
dependency/impact on other parameters of config file
b) show running-config/write config will display the fpm
information if configured. and will not display any
information related to fpm for default configuration
c) these configured information will be stored to config file.
only on write config command.
6.3 loading from config file
a) zebra attempts to connect to fpm server if fpm parameter
found in config file.else connects to default parameters.
b) if fpm connection drops, fpm will periodically attempts to
connect to remote server.
c) if fpm connections already established. then newly
configured fpm parameters will not disconnect the existing
connection. new connection to the different fpm server will
happen only after existing connection closes by either of
the end.

The Forwarding Plane Manager (FPM) is an optional component that may
be used in scenarios where the router has a forwarding path that is
distinct from the kernel, commonly a hardware-based fast path. It is
responsible for programming forwarding information (such as routes and
nexthops) in the fast path.
In Quagga, the Routing Information Base is maintained in the 'zebra'
infrastructure daemon. Routing protocols communicate their best routes
to zebra, and zebra computes the best route across protocols for each
prefix. This latter information comprises the bulk of the Forwarding
Information Base.
The new header file added by this patch, 'fpm/fpm.h', defines a
point-to-point interface using which zebra can update the FPM about
changes in routes. The communication takes place over a stream
socket. The FPM listens on a well-known TCP port, and zebra initiates
the connection.
All messages sent over the connection start with a short 'FPM header'.
In the case of route add/delete messages, the header is followed by a
netlink message. Zebra should send a complete copy of the forwarding
table(s) to the FPM, including routes that it may have picked up from
the kernel.
The FPM interface uses replace semantics. That is, if a 'route add'
message for a prefix is followed by another 'route add' message, the
information in the second message is complete by itself, and replaces
the information sent in the first message.
If the connection to the FPM goes down for some reason, the client
(zebra) should send the FPM a complete copy of the forwarding table(s)
when it reconnects.
