Problem reported with output of the command "show bgp vrf all
neighbor x.x.x.x" not limiting the output to that peer in any vrf.
This fix corrects the logic to display by neighbor
(ipv4/ipv6/interface) in any vrf.

The bestpath multipath-relax setting was added to the output of
"show ip bgp neighbor json" several months ago but this is not
the correct place to display that information and this fix removes
it from there. The multipath-relax setting was also added
to the output of "show ip bgp sum json" which is fine.

If we have configured neighbor 1.1.1.1 for an afi/safi but they have not
activated that afi/safi with us then display "NoNeg" in the state column
of the summary output. This is to make troubleshooting afi/safi
easier.

For some reason bgp is calculating the peer uptime
in miliseconds incorrectly. Additionally we have
the peer_uptime function call that should be doing this!
But since we've choosen different names for the json output
we cannot fix it at this point.
uptime contains the number of seconds of uptime here. Just
multiply by 1k and display that( as peer_uptime does )

BGP VRF can be created/deleted either via config or via l3vni add/del.
We need to handle various sequences.
1. If user config is presented, an l3vni del should not delete the vrf instance
2. do not write bgp config in show running for auto created vrf
2. If l3vni present, disallow the cli for deleting bgp vrf instance
3. If l3vni is added and vrf config is present set the flags properly
4. if bgp vrf is configured unset the AUTO flag

Since coalesce time is now heuristically adjusted based on peer count,
we need to separate out specific configuration by the user from the
current value. Behavior established is to not adjust if the user has a
value set.

bgpd supports setting a write-quanta that serves as a hint on how many
packets to write per I/O cycle. Now that input is buffered, it makes
sense to add the equivalent parameter for how many packets are processed
per cycle. This is *not* how many packets are read off the wire per I/O
cycle; rather it is how many packets are processed from the input buffer
in a given cycle after having been read off the wire and sanitized.
Since these values must be used from multiple threads, they have also
been made atomic.

* Move and modify all network input related code to bgp_io.c
* Add a real input buffer to `struct peer`
* Move connection initialization to its own thread.c task instead of
piggybacking off of bgp_read()
* Tons of little fixups
Primary changes are in bgp_packet.[ch], bgp_io.[ch], bgp_fsm.[ch].
Changes made elsewhere are almost exclusively refactoring peer->ibuf to
peer->curr since peer->ibuf is now the true FIFO packet input buffer
while peer->curr represents the packet currently being processed by the
main pthread.

* Remove t_write
* Remove t_keepalive
These have been replaced by pthreads and are no longer needed. Since
some code looks at these values to determine if the threads are
scheduled, also add a new bitfield to store the same information.

Fixes a bug whereby all peer-groups would be shown even when a
particular peer-group was specified for display.

Problem reported that we weren't adjusting the keepalive timer
correctly when we negotiated a lower hold time learned from a
peer. While working on this, found we didn't do inheritance
correctly at all. This fix solves the first problem and also
ensures that the timers are configured correctly based on this
priority order - peer defined > peer-group defined > global config.
This fix also displays the timers as "configured" regardless of
which of the three locations above is used.

VARIABLE tokens must be all uppercase, this allows us to support WORD
tokens that begin with an uppercase letter. The "Null0" keyword is an
example of where this is needed.
The only VARIABLE we had that wasn't already all uppercase was

afi_header_vty_out() is easily replaced with vty_frame(), which means we
can drop a whole batch of "int *write" args as well as the entirety of
bgp_config_write_family_header().
