Debug support

[Richard Sharpe]

Hi folks,

for the multithreaded SMB server I am writing, I have adopted a slightly
different approach than Samba, but have copied ideas liberally from Samba.
I trust that presents no problems.

My approach is that I will have a debug level and several modules, for
example:

   DEBUG_MAIN
   DEBUG_MEM
   DEBUG_THREAD
   DEBUG_RFC1001
   DEBUG_NETBEUI
   DEBUG_SMB

and each debug statement nominates which module it relates to.

After I get my command line parsing code done, I will then be able to
specify which module I am interested in seeing the DEBUG statements from.

So, if I only want to see the debug statements from memory management, I
simply specify on the command line:

   -dMEM:4

This has already allowed me to simply see that I have quite a lot of memory
leaks (in one test run, 9000 allocates versus 3000 frees).

This approach allows me to concentrate on one area rather than seeing heaps
of debugging statements from all over the code.
