There is no need to check for failure of a ALLOC call
as that any failure to do so will result in a assert
happening. So we can safely remove all of this code.

When `bfdd` is enabled - which it is by default - re-route the PTM-BFD
messages to the FRR's internal BFD daemon instead of the external
PTM daemon.
This will help the migration of BFD implementations and avoid
duplicating code.

When calling route_map_finish, every place that we do we must
first set the deletion event to NULL, or we will create an infinite
loop, if we are using the delayed route-map application code.
As such we might as well just make the route_map_finish code
do this work, as that there is really no viable alternative here
and route_map_finish should only be called on shutdown.
This fixes an infinite loop in zebra on shutdown when there
are route-maps.

Modify stream_new in this way:
1) ALLOC allocations do not fail, they cause a crash so remove
if tests for it.
2) Modify usage of XCALLOC to XMALLOC and then hand set all the
relevant data in the stream pointer.
With this modification stream allocation of 10000000 streams at
10k bytes each reduced from on average 1.43 seconds to 0.65 seconds.

EVPN ND ext community support NA flag R-bit, to have proxy ND.
Set R-bit in EVPN NA if a given router is default gateway or there is a
local
router attached, which can be determine based on local neighbor entry.
Implement BGP ext community attribute to generate and parse R-bit and
pass along zebra to program neigh entry in kernel.
Upon receiving MAC/IP update with community type 0x06 and sub_type 0x08,
pass the R-bit to zebra to program neigh entry.
Set NTF_ROUTER in neigh entry and inform kernel to do proxy NA for EVPN.

If your daemon does not need any special privileges
and you are compiling with HAVE_CAPABILIES, the
zprivs->change pointer will end up NULL due
to the way zprivs_caps_init. So as a check
let's add a NULL check for zprivs->change
and set it to a function that will do nothing.
This change prevents a crash if you raise privileges

The read in of cli was happening prior to thread
event handling for non-integrated configs. This
is interesting for 2 reasons:
1) Read-in of integrated configs was after thread
event loop startup, so we had a difference of behavior
2) Read-in can cause a series of events that cause
us to attempt to communicate with zebra. The zebra
zapi connection only happens after the thread event
loop has been started. This can cause data that
is being written down to zebra to be lost and
no real way to notice that this has happened and
to recover gracefully.
Modify the code to create a thread event for read
in of client config.
