gdb: Add command completers for some info commands

Browse source 
Add command completion for info variables, functions, args, and
locals.  This completer only completes the command line options as
these commands all take a regexp which GDB can't really offer
completions for.

gdb/ChangeLog:

	* cli/cli-utils.c (info_print_command_completer): New function.
	* cli/cli-utils.h: Add 'completer.h' include, and forward
	declaration for 'struct cmd_list_element'.
	(info_print_command_completer): Declare.
	* stack.c (_initialize_stack): Add completer for 'info locals' and
	'info args'.
	* symtab.c (_initialize_symtab): Add completer for 'info
	variables' and 'info functions'.
	* NEWS: Mention completion for additional info commands.
