[RFC] Fix the MI result of -break-insert with multiple locations

[Mircea Gherzan <mircea.gherzan@intel.com>]

The current MI output when printing a breakpoint with multiple locations
is not conformant to the MI specification:

  bkpt={number="1", ...},{number="1.1", ...},{number="1.2", ...}

This patch fixes this issue by moving the locations to a list inside the
first tuple:

  bkpt={number="1", ... , locations=[{number="1.1", ...}, ...]}

2013-01-28  Mircea Gherzan  <mircea.gherzan@intel.com>

	* breakpoint.c (print_one_breakpoint): Use a list of breakpoint
	locations that adheres to the MI specification.
