lib: Add lua noop decoder
Use this noop decoder for const values (since we can't mutate a const
value passed into frrscript_call anyways) or values we don't want to
write a decoder for.

lib: Add decoder functions
Split existing lua_to* functions into two functions:
- lua_decode_*: unmarshall Lua values into an existing C data structure
- lua_to*: allocate *and* unmarshall Lua values into C data structure
This allows us to mutate C data structures passed into frrscript_call,
without allocation

lib: remove pure attribute from functions that modify memory
Almost all functions currently marked with pure attribute acquire a
route_node lock. By marking them pure we allow compiler to optimize the
code and not call them when it already knows the return value. This is
completely incorrect.
Only two of eleven functions can be marked as pure. And they still won't
be optimized because they are never called from the same function twice.
Let's remove the ext_pure macro completely to reduce the chance of
repeating this mistake in the future.

ospf6: Drop LSA with bad seqnumber
In RFC 2328 seqnumber 0x80000000 is reserved and not used. If an LSA

ospf6d: Set metric from default values when route-map metric not present
For redistribute commands if route map is set, then route takes it's metric
values from the route map. But in the case that routemap is set but the
metric for the route map is not, then the route metric is set to type-1.
Check if the metric is set for the routemap. If not then set it as per

docker: Use tini unilaterally and stop tailing /dev/null
tini is a hyper-minimal PID 0 which spawns a child process (watchfrr.sh
in our case), reaps zombies and forwards signals to the script. Starting
watchfrr.sh directly instead of through the old `tail /dev/null` or
`sleep 365d` helps keep things clean too :)
While tini was previously only used in the Alpine container it is useful
to apply this PID 0 to all containers except the special CI ones.

ospf6d: move error logs out from behind debug flags
The logging in ospf6 is very verbose. If you turn on logging on a scaled
system you get too many logs. The problem is that there are some errors
that occur that are hidden behind the debug flags, and to see these errors
we currently need to turn on the debug logging. This change converts these
error logs to warnings and removes the debug flags.

isisd: per-instance dynamic hostname cache
Currently, the dynamic hostname cache is global. It is incorrect because
neighbors in different VRFs may have the same system ID and different
hostnames.
This also fixes a memory leak - when the instance is deleted, the cache
must be cleaned up and the cleanup thread must be cancelled.

Fully utilize the northbound to hold pointers to our private data

* Support multiple mesh groups per PIM instance (instead of one)
* Use DEFPY instead of DEFUN to reduce code complexity
* Use northbound private pointers to store data structures
* Reduce callback names size

zebra: Give extra space and stop processing if we run out of space
When processing bulk messages we need more space to handle more
mroutes. In this case we are doubling the stream size from
16k -> 32k, which should roughly double the number of mroutes
we can handle in one go.
Additionally. If we cannot parse the passed message into
the stream to pass up to pimd then gracefully stop processing
