[PATCH] Add the "-info-os" command to MI

This patch adds the "-info-os" command to MI as the counterpart to the GDB "info os" command. It behaves in the same way as "info os", only the output is formatted according to MI conventions. I've also added an entry in the documentation.



	* mi/mi-cmds.c (mi_cmds): Add -info-os MI command.

	* gdb.texinfo (Operating System Auxilliary Information): Change
	the name of the information types anchor to be more readable.
	(Miscellaneous gdb/mi Commands): Document the -info-os MI command.
