This fix aims to reduce the load on BGPD when certain
exisiting configurations are replayed.
Specifically, the fix prevents BGPD from processing
routes when the following already existing configurations
are replayed:
1) A match criteria is configured within a route-map.
2) When "call" is invoked within a route-map.
3) When a route-map is tied to a BGP neighbor.

Route map library creates a hash table to save the dependency binding.
route-map LRM permit 1
call rLRM
Whenever there is change in child routemap(rLRM), it tries to
find the dependency mapping with the child route map MATCH event
and it fails.The handing of match add and match delete was missing
to get the correct dependency,here it's LRM.
This fix would correct the flow to get the correct dependency.

Made the following changes.
1.Defined two apis in routemap-lib, one for increment and another for
decrement the applied counter.
2.Added a new configuration “show route-map-unused” to track all unused
routemaps.
3.called the corresponding route map update api when a route map attached
or detached from any redistribution list.

The ->hash_cmp and linked list ->cmp functions were sometimes
being used interchangeably and this really is not a good
thing. So let's modify the hash_cmp function pointer to return
a boolean and convert everything to use the new syntax.

Keep track of how often route-maps are applied and
how often each clause of a route-map is applied.
This change showed that `show route-map` was outputting
odd data so fix that output and add in the applied
times too.

When the "call" CLI is executed from with-in a route-map that is already in use,
there is a need to get the route-map clients to re-evalute the clauses defined
by both the parent route-map, as well as the child route-map.
The existing callbacks, add_hook() and delete_hook() can be used by the lib to
inform the clients when the "call" is configured and unconfigured.

When calling route_map_finish, every place that we do we must
first set the deletion event to NULL, or we will create an infinite
loop, if we are using the delayed route-map application code.
As such we might as well just make the route_map_finish code
do this work, as that there is really no viable alternative here
and route_map_finish should only be called on shutdown.
This fixes an infinite loop in zebra on shutdown when there
are route-maps.

1) Some hash key functions where converting pointers
directly to a 32 bit value via downcasting. Pointers
are 64 bit on a majority of our platforms.
2) Some hashes were being created with 256 entries,
downsize the hash creation size to more appropriate
values.
3) Add hash names to hash creation so we can watch
the hash via 'show debugging hashtable'

Add the RMAP_COMPILE_SUCCESS and switch over to using it.
Refactoring allows a removal of a if statement to just
use the switch statement already in place. Additionally
the reworking cleans up memory freeing in a couple of spots.
In one spot we no longer will leak memory too.
