Add a zapi message type designed to carry opaque data. Add
'send' api, and prototype for client handler function. Also
add registration/unreg messages, so that clients can 'subscribe'
to receive these messages as they're passing through zebra.

Add utilities that init and deinit a stream_fifo - this lets us
use an on-stack fifo in some places, avoiding malloc'ing. Also
add const to some apis (no functional changes there).

Move some processing of zapi label messages so they can be
handled more efficiently. Handle zapi delete and replace
messages.

Add a 'check' api to hold the code that determines whether an LSP
can be freed or not. Replace calls to the free api with check
calls.

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.

bgp_accept() gets called over and over again when a VRF device is
deleted out from under a bgp listener socket that is bound to it.
Prevent this by noting the error and cancelling ourselves, allowing the
vrf status code to clean up the mess when it receives word about the
change from Zebra.

Alpine builds have been failing for some time as a consequence of only
installing python 2 development packages when we have build scripts that
require python 3.

Try to give a bit more useful data about where we
think the connection is trying to come in from.
Hopefully this will let us debug connection issues
a bit faster in cases where there are config issues.

Just add a basic test for pbr. This code
does not actually test installation in the kernel at this
point in time.
What we do do is make sure pbr is in a sane state after
some very basic configuration.

Just a simple setup for pbr to prove it starts. Once the json
code for pbr gets in we can add more.

"set community accept-own-nexthop" returns "malformed communities"
error. This is because the token matching hits an earlier "accept-own"
and leaves "-nexthop" as a separate token to be processed.
Reorder the switch cases so that both are processed correctly.

we were not correctly checking the MPLS-TE status of the area when
adding an IP address to a circuit, and this was preventing the local
address TLV to be populated after an interfaced flap.

Updated documentation for routers with a large route table, which breaks
SNMP/AgentX and in some conditions even crashes FRR. The documentation
proposal amends the SNMP configuration to exclude certain OID's that
are not needed in normal cases.

We are crashing in thread_cancel on shutdown because
the thread pointer is NULL. Use the more appropriate

`debug zebra packet detail` dumps the full message whereas
it had been dropping exactly 10 bytes, the size of the zebra header

We were using thread_cancel() directly instead of
THREAD_OFF which correctly ensures the pointer is not NULL.
