[chirp_devel] [PATCH 3/4] Simplify and centralize debugging messages (#2343)

I recall an unfinished discussion a while back where we were thinking that chirp should have proper logging support. One thought was to have a more complete logging subsystem, e.g., thru logger module. This would be more flexible in terms of supporting various levels i.e., CRIT, WARN, INFO, DEBUG, as well as various outputs, e.g., logfile, console, etc.

It does seem to be a rather large task, as you have begun undertaking.Thanks for taking this on Zach. This looks like a great start.

 Subject: [chirp_devel] [PATCH 3/4] Simplify and centralize debugging messages (#2343)
   
At its core, this patch adds a dprint function that wraps print with
a conditional on CHIRP_DEBUG.  That variable is set by the environment,
but it can also be set by a command line option (--debug) in chirp.py.
I would like to add that option to chirpw too, but that would require a
separate patch that adds proper option parsing.

The remainder of the patch involves chasing down all references to
CHIRP_DEBUG, nearly all of which were wrapping plain print statements.
I also eliminated a few plain DEBUG variables and a couple of other
one-off variants.
