getrusage, in a heavily stressed system, can account for
signficant running time due to process switching to the kernel.
Allow the end-operator to specify `--disable-cpu-time` to
avoid this call. Additionally we cause `show thread cpu` to
not show up if this is selected.

this table identifier can be used for policy routing. incoming entries
are locally exported to that local table identifier.
note that so that the user applies the new table identifier to all
entries, the user should flush local tables first.

FRR supports the ability to turn off the negotation of bgp capabilities.
Provide a few bread crumbs to the operator that it might not be as
useful as they would hope.

Current autocompletion works only for simple "vrf NAME" case.
This commit expands it also for the following cases:
- "nexthop-vrf NAME" in staticd
- usage of $varname in many daemons
All daemons are updated to use single varname "$vrf_name".

In a data center, having 32-128 peers is not uncommon. In such a situation, to find a
peer that has failed and why is several commands. This hinders both the automatability of
failure detection and the ease/speed with which the reason can be found. To simplify this
process of catching a failure and its cause quicker, this patch does the following:
1. Created a new function, bgp_show_failed_summary to display the
failed summary output for JSON and vty
2. Created a new function to display the reset code/subcode. This is now used in the
failed summary code and in the show neighbors code
3. Added a new variable failedPeers in all the JSON outputs, including the vanilla
"show bgp summary" family. This lists the failed session count.
4. Display peer, dropped count, estd count, uptime and the reason for failure as the
output of "show bgp summary failed" family of commands
5. Added three resset codes for the case where we're waiting for NHT, waiting for peer
IPv6 addr, waiting for VRF to init.
This also counts the case where only one peer has advertised an AFI/SAFI.
The new command has the optional keyword "failed" added to the classical summary command.
The changes affect only one existing output, that of "show [ip] bgp neighbors <nbr>". As
we track the lack of NHT resolution for a peer or the lack of knowing a peer IPv6 addr,
the output of that command will show a "waiting for NHT" etc. as the last reset reason.
This patch includes update to the documentation too.

This implements BMP. There's no fine-grained history here, the non-BMP
preparations are already split out from here so all that remains is BMP
proper.

Problem reported that "clear bgp *" only cleared ipv6 peers.
Changed the logic to clear all afi/safis of all peers in
that case. Also improved the operation of clearing
individual afi/safi using soft/in/out to do the right thing.

Add notes to several docs about the limits to FRR's current
MPLS-TE support, which is limited to some routing protocol
LSA/TLV support. It wasn't very clear that FRR does not offer
a complete TE/RSVP-TE solution at this time.
Also removed some stale info about configure script options.
