The previous method, using zassert.h and hoping nothing includes
assert.h (which, on glibc at least, just does "#undef assert" and puts
its own definition in...) was fragile - and actually broke undetected.
Just provide our own assert.h and control overriding by putting it in a
separate directory to add to the include path (or not.)

When an operator encounters a situation where the number
of FD's open is greater than what we have been configured
to legitimately handle via uname or the `--limit-fds` command
line, abort with a message that they should be able to
debug and figure out what is going on.

Delay setting local data about a remote peer until after BGP

Modifying local peer data structures based upon what is
received from a peer should not be done until after BGP
has decided that the open is allowed to proceed.

FRR in thread.c clears the passed in double pointer when

Initially the reading of the speed of an interface happened
upon interface creation and happened until the speed of a link
settled down to a single value. The speed of an interface
can also change as that a new optic can be inserted that
changes the speed, in which case FRR would see a interface
down (optic removal) and then a interface up (optic insertion).
In this case FRR would not treat this as an event that changed
the speed. Let's expand the checking a bit more.

When enabling TI-LFA the forward SPF for neighbors adjacent to the
PLR is computed. Later, when computing the PQ spaces, the reverse
SPF trees for those adjacent neighbors affected by the protected
interface are computed.
When node protection is enabled, TI-LFA link protection is run
immediately afterwards to compute repairs in case no
node-protecting backup path exists. In this second run, the
existing code tries to compute the reverse SPF tree for the same
node, without freeing the SPF tree of the prior run.
This patch fixes this by not computing the reverse SPF again, thus
avoiding a memory leak and an unnecessary SPF run.

As pointed out on code review of BGP extended messages, increasing the
maximum BGP message size has the consequence of growing the dynamically
sized stack buffer up to 650K. While unlikely to exceed modern stack
sizes it is still unreasonably large. Remedy this with a heap buffer.

Description:
This looks broken after NB changes in routemap. When routemap
action modified from permit to deny, it is expected to apply
the new action on the filtered routes before the action in the
routemap data structure has been changed. But currently this is
not handled by the corresponding northbound API.

YANG model and CLI commands allow user to configure LDP-sync per area.
But the actual implementation is incorrect - all commands are changing
the config for the whole VRF instead of a single area. This commit fixes
this issue by actually implementing per area configuration.
Fixes#8578.

Currently we don't allow to configure the interface before the area is
configured. This approach has the following issues:
1. The area config can be deleted even when we have an interface config
relying on it. The code is not ready for that - we'll have a whole
bunch of stale pointers if user does that.
2. The code doesn't correctly process the event of changing the VRF for
an interface. There is no mechanism to ensure that the area exists
in the new VRF so currently the circuit still stays in the old VRF.
This commit allows an arbitrary order of area/interface configuration.
There is no more need to configure the area before configuring the
interface.
This change fixes both the issues.

Necessary structures for snmp-id generation are currently stored in
`struct isis`. When we generate the new circuit ID, we always use the
instance from the default VRF. When we free the circuit ID, we use the
instance from the circuit VRF. This causes the following problems:
1. If there is no instance in the default VRF, this code doesn't work.
2. When circuit in non-default VRF is deleted, the ID is not actually
freed.
This is fixed by using global structures instead. The code itself is
moved to isis_snmp.c and linked to the main code using hooks. We should
not call SNMP-related code when the SNMP module is not loaded at all.
More than that, we don't allow to activate the circuit if we failed to
generate the SNMP ID. Even if SNMP support is completely disabled! This
check is removed.

This change allows the user to only log the message header and not
include all the LSAs in each packet. In a large setup printing out
all the LSAs in each packet can make the system very hard to debug.
When the user finds an issue with the adjacency not coming up or in a
specific packet type they can turn on a full dump of the message.

a) `debug zebra kernel` turns off `debug zebra kernel msgdump....`
this is odd and bad
b) `debug zebra kernel msgdump send` turns off receive and vice versa
this is counter intuitive as well
c) `no zebra kernel msgdump ...` turns off all kernel level debugging
we should only turn off msgdump specific debugs
d) `no debug zebra kernel` turns off all kernel level debugging
we should leave msgdump on.

frr(config-ospf6)# do show ipv6 ospf6 route json
