Support shell wildcards for 'set auto-load safe-path'.
	* auto-load.c: Include fnmatch.h.
	(filename_is_in_dir): Rename to ...
	(filename_is_in_pattern_1, filename_is_in_pattern): ... here and split
	it.  Update function comment.  Rename dir_len to pattern_len.  New
	variables filename_len, pattern and filename.  Add more DEBUG_AUTO_LOAD
	messages.  Use gdb_filename_fnmatch.
	(filename_is_in_auto_load_safe_path_vec): Rename variable dir to
	pattern.
	(_initialize_auto_load): Extend the "set auto-load safe-path" help text.
	* defs.h (gdb_filename_fnmatch): New declaration.
	* utils.c: Include fnmatch.h.
	(gdb_filename_fnmatch): New function.

gdb/doc/
	* gdb.texinfo (Auto-loading safe path): Note the shell wildcard
	possibility.
