Consolidate duplicated string matching code.

* search.c (fast_string_match_internal): New function,
consolidated from...
(fast_string_match, fast_string_match_ignore_case): ...functions
which are...
* lisp.h (fast_string_match, fast_string_match_ignore_case):
inlined from here now.
(fast_string_match_internal): Add prototype.
* dired.c (file_name_completion): Use fast_string_match_internal.
