Fix some issues with mod_mime_magic. Basically, we need to include

apr_strings.h, the command table needed to be fixed to use the new
format, and we had vestiges of stat left around.

The top two issues are simple, we include apr_strings and fix the command
recs.

The last issue required using APR enums instead of the stat.h macros.  This
also allows us to remove some ugly #ifdefs.  :-)
