When debugging the mroute code path in zebra, add a bit of additional
data to allow us to know what is going on a bit more.

* Add centralized thread scheduling dispatchers for client threads and
the main thread
* Rename everything in zserv.c to stop using a combination of:
- zebra_server_*
- zebra_*
- zserv_*
Everything in zserv.c now begins with zserv_*.

Group send and receive functions together, change handlers to take a
message instead of looking at ->ibuf and ->obuf, allow zebra to read
multiple packets off the wire at a time.

A lot of the handler functions that are called directly from the ZAPI
input processing code take different argument sets where they don't need
to. These functions are called from only one place and all have the same
fundamental information available to them to do their work. There is no
need to specialize what information is passed to them; it is cleaner and
easier to understand when they all accept the same base set of
information and extract what they need inline.

All of the ZAPI message handlers return an integer that means different
things to each of them, but nobody ever reads these integers, so this is
technical debt that we can just eliminate outright.

The function zserv_create_header was exactly the same
as zclient_create_header. Let's just have one in the
system.

This code modifies zebra to use the STREAM_GET functionality.
This will allow zebra to continue functioning in the case of
bad input data from higher level protocols instead of crashing.

This current implementation unfortunately must
ask the kernel for all mroutes because vrf's
do not have the ability to request a single
mroute at this time.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

The code to collect the sg stats was written for linux.
Abstract the call to allow it to work on all platforms.
I have not implemented the call for non-linux systems.

When zebra asks for mroute information let pim
know that the request failed or succeeded.

When we need to lookup the mroute info for a route. Allow
pimd to ask the kernel.
