[PATCH 3/4] Transform \r\n in MI variables

[Yao Qi <yao@codesourcery.com>]

The previous patch can't transform \r\n in variables, so this patch
update these variables which have \r\n in MI.

gdb/testsuite:

2013-09-17  Yao Qi  <yao@codesourcery.com>

	* lib/mi-support.exp (mi_gdb_prompt): Replace "\r\n" with
	"\r+\n".
	(thread_selected_re): Likewise.
	(gdbindex_warning_re): Likewise.
	(library_loaded_re): Likewise.
	(breakpoint_re): Likewise.
