Summary:                    Use ast_verb instead of ast_debug for channel driver
debugging
Description: 
When turning on channel driver specific debugging (skinny set debug on),
it is cleaner to use ast_verb instead of ast_debug.

With core verbose set to 1, there is not a lot of output to the log
or console, but when core debug is set to 1 the logs can get quite
crowded.

MVanbaak-
   I do not believe I can assign reports/tickets, so I leave it to
one of our administrators or bug marshalls to assign it to you.

Common?

Channels that use a local debug variable & ast_verb (15%)
IAX2                MGCP
Unistim

Channels that use a local debug variable & ast_debug: (15%)
H323                SIP
Skinny (used to be verbose)

Channels that use a local debug and raw CLI output (15%)
MISDN               OSS (uses ast_log)
USBRadio (ast_log)

Channels that use ast_debug alone (55%)
gtalk               Agent
ALSA                Console
Features            Jingle
NBS                 Phone
VPB                 ZAP
Local

To make it even more interesting, I would not want to just
strip out the skinny_debug flag, I would want to try to assign
each message to a valid level.  So I gave a quick look at the
other channels use of ast_debug.

67% of all channel debuging is at level 1
13% is at level 3
13% is at level 4
7%  is at level 2
.1% is at level 5


I know that it has been discussed in the past to try
defining what type of reporting is desired at each level,
but I have not located any documentation to suggest a
concensus was reached.

In any case I guess the only way forward would be to stip
skinny_debug and leave everything at debug level 1 for now
so that we can be moving towards the common interface.
Even so, chan_skinny is far from unique in this regard.
