Provide a way for the data plane to indicate pseudowire
status (such as: not forwarding, AC failure).
On a data plane pseudowire install failure, data plane
sets the pseudowire status.
Zebra relays the pseudowire status to LDP.
LDP includes the pseudowire status in the LDP notification
to the LDP peer.

Add accessors for pw attributes; init pw attributes;
replace 'hook' calls for pw install/uninstall with dplane
apis.

zserv.c was using hardcoded callbacks to clean up various components
when a client disconnected. Ergo zserv.c had to know about all these
unrelated components that it should not care about. We have hooks now,
let's use the proper thing instead.

zserv.c has become something of a dumping ground for everything vaguely
related to ZAPI and really needs some love. This change splits out the
code fo building and consuming ZAPI messages into a separate source
file, leaving the actual session and client lifecycle code in zserv.c.
Unfortunately since the #include situation in Zebra has not been paid
much attention I was forced to fix the headers in a lot of other source
files. This is a net improvement overall though.

If the remote end of a pseudowire becomes unreachable (no route or an
unlabeled route), then it must be uninstalled. In the same way, when
the remote end becomes reachable, the pseudowire must be installed.

Base framework for supporting MPLS pseudowires in FRR.
A consistent zserv interface is provided so that any client daemon
(e.g. ldpd, bgpd) can install/uninstall pseudowires in a standard
way. Static pseudowires can also be implemented by using the same
interface.
When zebra receives a request to install a pseudowire and the installation
in the kernel or hardware fails, a notification is sent back to the
client daemon and a new install attempt is made every 60 seconds (until
it succeeds).
Support for external dataplanes is provided by the use of hooks to
install/uninstall pseudowires.
