JFS: add uid, gid, and umask mount options
OS/2 doesn't initialize the uid, gid, or unix-style permission bits. The
uid, gid, & umask mount options perform pretty much like those for the fat
file system, overriding what is stored on disk. This is useful for users
sharing the file system with OS/2.
I implemented a little feature so that if you mask the execute bit, it
will be re-enabled on directories when the appropriate read bit is unmasked.
I didn't want to implement an fmask & dmask option.
