Implement support for noticing new or modified mimetypes at runtime.

The binary provider checks the mtime of the mime.cache files, and
re-lists mime.cache files (not more often than once every 5 seconds).
Upon a change, it simply has to close, open and map() the file again.

The XML provider checks the list of xml files found (not more often
than once every 5 seconds) and if the list changes, reloads everything.

With unit tests for adding and removing a mimetype xml file, both
in an existing dir (global) and into a new dir (local).
