While terminating pim instance, the memory allocated for pim nexthop
should be released before deallocating the memory of pim nexthop cache(pnc).
This resolves the memory leak detected in pnc->nexthop creation.

In bgp_keepalives.c, it was noticed that we were
ensuring that we called an intialization function first,
but this is a development escape in that once this
was fixed we never see it. So if a developer moves
this assumption around, let's crash the program and
lead them to this spot instead of silently ignoring
the problem.

There exists a few places where actual debugs were being
displayed as warns. Convert them over to debugs and
guard as appropriate.

backet->data must be non-NULL( look at hash_get ) as such
we do not need to check for NULL values for this when
we retrieve data from the backet.
Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
The hash_get function when called and the alloc_func returns
a NULL value, we do not create a backet nor do we insert
anything into the hash. As such backet->data must always
be non-NULL.
Modify the description in hash_get to inform of this.
Additionally indicate that hash_walk and hash_iterate
cannot have a NULL backet->data value.

Improvements:
* Show command line as code, to avoid confusion about single dash (`-`)
and double dash;
* Tell the user where the BGP BFD commands can be found;
* Document OSPF/OSPF6/PIM BFD commands;
* Document JSON commands;
* Tell about session counters;

Added 3 new counters to BFD sessions:
* Session up events count;
* Session down events count;
* Zebra notifications count;
In addition to previosly available counters:
* Count of received control packets;
* Count of transmitted control packets;
* Count of received echo packets;
* Count of transmitted echo packets;
With this count we are able to visualize the BFD activity, bandwidth
usage, interface/network flapping and excess of zebra notifications.

Turn some code that will be repeated in the next commits into functions

The CMSG_FIRSTHDR was broken on solaris pre version 9. Version 9
was released in May of 2002 and EOL'ed in 2014. Version 8 EOL'ed
in 2012. Remove special case code for a little used platform
that has not seen the light of day in a very long time.

We were attempting to get around a unused value by setting
a variable to itself, but it runs afoul of a different
compiler and a message about not setting a variable to
itself. So let's mark the ttl value as unused.

Coverity warns about a possible double free; add an assert to make sure
we never hit it, and hopefully silence Coverity.

Used as:
frr_elevate_privs(&my_privs) {
... code ...
}
and handles privilege raise/lower automatically in conjunction with the
C expression block. This makes it impossible to accidentally exit a
function with privileges raised (and then running a whole bunch of other
code with privs.)
