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 base_dir The base directory of the filesystem to perform the match against
\param flags flags for the search. Can be any combination of ACCEPT_INCOMPLETE and EXECUTABLES_ONLY
