Separate out the debug_init api to have 2 functions:
1) Function to register a callback
2) Function to initiate the cli.

Allow multiple callers to initialize themselves to receive
callbacks for debug on/off operations.

The current strategy for fine-grained debugging across FRR is to use
static long int bitfields, in combination with helper macros that are
copy-pasted between daemons, to hold state on what debugging information
should be collected at any given time. This has a couple of problems:
* These bitfields are generally extern'd and accessed everywhere, so
they are not MT-safe or easy to make MT-safe
* Lots of code duplication from copy-pasting the DEBUG_* macros...
* Code duplication because of the "term" vs "conf" debugging concept
This patch aims to remedy that by providing some infrastructure to work
with debugs. The core concept of using bitfields has been retained, but
the number of these for each debug has been reduced to 1. This allows
easy use of lock-free methods for synchronizing access to debugging
info.
The helper macros have also been retained but they are now collected in
one place and perform exclusively atomic operations.
Finally there is a bit of code that allows daemons to register
callbacks, which I used to implement a command that will toggle all
debugging for any daemons that use these facilities.

* debug.[ch]: Remove unused files.
* Makefile.am: Remove references to debug.c and debug.h
* ospf_main.c: Remove #include "debug.h" (was not being used, and
lib/debug.h has now been deleted).
