logger:  Bring back ability to  turn debug on by source file

Somewhere along the way we lost the ability to debug individual
source files.  For modules, this wasn't a big deal but all the
source files in ./main are in the one "core" module so debugging
individual core capabilities was almost impossible.

* Added a new function "ast_debug_get_by_file" to logger.h/cli.c
which gets the debug level for a specific sourfe file.  You can now
do a "core set debug 3 bridge_channel.c" for instance, and only turn
debugging on for that since source file.  This isn't limited to
source files in ./main.  Any source file works so you could also do
"core set debug 3 pjsip_message_filter.c".
