Tested by: russell, bbryant

This set of changes introduces the ability to set the core debug or verbose
levels on a per-file basis.  Interestingly enough, in 1.4, you have the ability
to set core debug for a single file, but that functionality was accidentally
lost in the conversion of the CLI commands to the new format.

This patch improves upon what was in 1.4 by letting you set it for more than 1
file, and by also supporting verbose.

*** Janitor Project ***

This patch also introduces a new macro, ast_verb(), which is similar
to ast_debug().  Setting the per file verbose value only works for messages that
use this macro.  Converting existing uses of ast_verbose() can be done like:

if (option_debug > 2)
   ast_verbose(VERBOSE_PREFIX_3 "Something useful\n");

...

ast_verb(3, "Something useful\n");
