[PATCH v4 0/9] Locations API

[Keith Seitz <keiths@redhat.com>]

This is the next revision of the locations/explicit locations mega-API
change on which I've been working. Most of the changes in this
revision are fairly trivial.

As a reminder, this series proposes to change the API for create_breakpoint
and related functions to:

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

  location = string_to_event_location (&arg, current_language);
  cleanup = make_cleanup_delete_event_location (location);
  if (*arg)
    error ("junk at end of command");
  /* do whatever with location, e.g., create_breakpoint (location, ...);  */
  do_cleanups (cleanup);
}

As with the previous revision, explicit-ui-cli tests will cause several
internal-errors because of gdb/17960 (internal-error when completing
"source.c:func").

This is easily fixed after that patch has been committed. This series
sent as-is does /not/ depend on those patches being applied.
