Update md5 routines
XySSL 0.9 was released; sync our code with the upstream source. Note that there weren't any real changes besides renaming of macros, so nothing much to see here. The biggest change may be the licence- it is now GPL/BSD software rather than LGPL/BSD. The license header is changed to reflect this. Signed-off-by: Dan McGee <dan@archlinux.org>
