Code

A while back, Andrew and I talked about making the debug parsing code a

better "fit" with other Samba code.  This is a small first step toward
doing what (I think) we agreed to do.

I've moved the key function from ubiqx/debugparse.c into lib/debug.c.  I
have also moved the enum from ubiqx/debugparse.h into the debug section in
smb.h.

The next thing to do is to get debug2html added into the Makefile.in so
that it is always produced when compiling the suite.
