    Expand the wildcard by matching against the filesystem. 

	New strings are allocated using malloc and should be freed by the caller.

	wildcard_expand works by dividing the wildcard into segments at
	each directory boundary. Each segment is processed separatly. All
	except the last segment are handled by matching the wildcard
	segment against all subdirectories of matching directories, and
	recursively calling wildcard_expand for matches. On the last
	segment, matching is made to any file, and all matches are
	inserted to the list.

	If wildcard_expand encounters any errors (such as insufficient
	priviliges) during matching, no error messages will be printed and
	wildcard_expand will continue the matching process.

	\param wc The wildcard string
	\param base_dir The base directory of the filesystem to perform the match against
	\param status flags for the search. Can be any combination of ACCEPT_INCOMPLETE and EXECUTABLES_ONLY
	\param out The list in which to put the output

	\return 1 if matches where found, 0 otherwise.
