This patch converts the code base to use the new struct event_location
API being introduced. This patch preserves the current functionality and
adds no new features.

The "big picture" API usage introduced by this patch may be illustrated
with a simple exmaple. Where previously developers would write:

void
my_command (char *arg, int from_tty)
{
   create_breakpoint (..., arg, ...);
   ...
}

one now uses:

void
my_command (char *arg, int from_tty)
{
   struct event_locaiton *location;
   struct cleanup *back_to;

   location = string_to_event_locaiton (&arg, ...);
   back_to = make_cleanup_delete_event_location (location);
   create_breakpoint (..., location, ...);
   do_cleanups (back_to);
}

Linespec-decoding functions (now called location-decoding) such as
decode_line_full no longer skip argument pointers over processed input.
That functionality has been moved into string_to_event_location as
demonstrated above.
