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.
