Harmonize this monitor_load with generic_load.

Harmonize this old-looking code with generic_load, which fixes several
issues.

2013-02-19  Pedro Alves  <palves@redhat.com>

	PR gdb/15161

	Harmonize with generic_load.

	* monitor.c: Include "readline/readline.h".
	(monitor_load): Rename parameter 'file' to 'args'.  Use build_argv
	instead of sscanf.  Use CORE_ADDR/strtoulst instead of unsigned
	long/strtol for the 'load_offset' local.  Error out if no argument
	is given or if too many arguments are given.  Tilde expand the
	passed in file name.
