zebra: When using BFD ensure that zebra thinks ptm is disabled
In order for connected routes to be installed the if_is_operative
function is called. This function checks the status of ptm
and decides to use ptm enabled/disabled on the interface.
The call to zebra_ptm_get_enable was returning true and causing
the interface subsystem to do the wrong thing. Modify the
internal bfd case to when checking for ptm enabled to say it
is not enabled.

pimd: Fix memory leak pim nexthop creation
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.

bgpd: zlog_warn to assert for code that must be executed first
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.

lib: Update hash.h documentation
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.

bfdd: improve docs
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;

bfdd: add new counters and command to show them
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.
