Added -h instead of -?. And upon -h and --help, write usave to stdout
instead of stdin, and return 0 instead of 1.
-? still works like before as that's what getopt returns upon unknown
arguments.
fonts.cache-1 files (e.g. for grepping and validation of the mmap
codepath), as per James Cloos' request.
Remove done 'TODO' comment.
Updates for development release 2.3.90.
fc-cache once per cached architecture; add some documentation to the
FcCache structure.
Make fc-cache write out fonts.cache-2 files for directories with no fonts
(i.e. only subdirectories).
