cae8bc967c *: Remove solaris from FRR
The Solaris code has gone through a deprecation cycle.  No-one
has said anything to us and worse of all we don't have any test
systems running Solaris to know if we are making changes that
are breaking on Solaris.  Remove it from the system so
we can clean up a bit.

1eb92f06c4 vrf: VRF_DEFAULT must be 0, remove useless code
Code was added in the past to support a value of VRF_DEFAULT different
from 0. This option was abandoned, the default vrf id is always 0.

Remove this code, this will simplify the code and improve performance
(use a constant value instead of a function that performs tests).

6ac9404177 zebra: simplify and optimize vrf display in show ip route
In all outputs (text and json): simplify and optimize the vrf name
display, use the vrf_id_to_name() handler.

Note: vrf_id_to_name() has a safeguard system that prevents from
crashing when the vrf cannot be found because it changed in some
(unexpected) manner, it returns "n/a".

Note: "vrf n/a" will now be displayed instead of "vrf UNKNOWN" in this
case, like in most other frr components.

This safeguard was missing for show ip route json, so this
optimization also fixes a potential crash.

8277d4b796 zebra: fix show ip route output
Variable "show ip route" commands invoke the same helper
(do_show_ip_route), potentially several times.

When asking to dump a non-default vrf, all vrfs or all tables, the
output is messy, the header summarizing abbreviations is repeated
several times, excess line feeds appear, the default table of default
VRF is concatenated to the previous table output...

Normalize the output:

- whatever the case, display the common header at most once, if there
  is at least an entry to dump.

- when using a "vrf all" or "table all" command, prepend a line with
  the VRF and table (even for the default vrf or table).

- when dumping a specific vrf or table, prepend a line with the VRF
  and table.

Example (vrf all)

8c36640b7c zebra: Allow FreeBSD to set and delete addresses from an interface
This series of events:

$ sudo ifconfig lo0 add 4.4.4.4/32
$ sudo ifconfig lo0 inet 4.4.4.4/32 delete

would end up leaving the 4.4.4.4/32 address on the interface under
freebsd.

This all boils down to the fact that the interface is not
considered connected yet we have a destination.  If the
destination is the same and we are not connected ignore
it on freebsd.

I am sure there are other fun scenarios that someone
will have to squirrel out.

fdaee098f3 tools: fix vtysh failure error handling
Based on the current code, I think the intent was to gracefully handle
vtysh failures and print a useful error message. Barriers in the way of
that:

- Despite reading the results of subprocess.communicate(), there won't
  be anything there, because we aren't passing subprocess.PIPE as stdin
  and stderr when calling subprocess.Popen()
- Despite catching subprocess.TimeoutExpired, if we were to actually hit
  this case frr-reload.py would just crash because it's calling
  .communicate() on an unbound process variable, probably a copy-paste
  error
- Aside from that, building a kwargs dict to pass to a function that
  contains something if something else is not None and nothing if it is,
  is pointless when we could just pass the thing itself

Net result is that if vtysh fails to read an frr.conf due to syntax
errors, instead of crashing with a traceback, we actually handle the
error condition, log the problem and vtysh's output, and exit. Actually
we were printing the failed line just by chance because stderr wasn't
captured from the subprocess and I guess showed up as part of systemd's
error capturing or something, but the traceback did a good job of
obscuring that with useless noise.

In a topology like R1 -- R2 -- R5, with R2 being NSSA ABR and R5 being
ASBR redistributing external routes, the ABR R2 will translate type-7
LSA into type-5 and advertise to the backbone. In the current implementation
R2 is also advertising a type-4 LSA when there is no need.

RFC 3101: "...NSSA's border routers never originate Type-4 summary-LSAs
for the NSSA's AS boundary routers, since Type-7 AS-external-LSAs are
never flooded beyond the NSSA's border..."

With this PR a type-4 LSA will not be advertised
