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.

JFS: ext2 inode attributes for jfs

ext2 inode attributes with relevance for jfs:

'a' EXT2_APPEND_FL -> append only
'i' EXT2_IMMUTABLE_FL -> immutable file
's' EXT2_SECRM_FL -> zero file
'u' EXT2_UNRM_FL -> allow for unrm
'A' EXT2_NOATIME_FL -> no access time
'D' EXT2_DIRSYNC_FL -> dirsync
'S' EXT2_SYNC_FL -> sync

overview of jfs flags (partially for OS/2)

value (OS/2) Linux ext2 attrs
------------------------------------------------
0x00010000 IFJOURNAL -
0x00020000 ISPARSE used
0x00040000 INLINEEA used
0x00080000 - - JFS_NOATIME_FL

0x00100000 - - JFS_DIRSYNC_FL
0x00200000 - - JFS_SYNC_FL
0x00400000 - - JFS_SECRM_FL
0x00800000 ISWAPFILE - JFS_UNRM_FL

0x01000000 - - JFS_APPEND_FL
0x02000000 IREADONLY - JFS_IMMUTABLE_FL
0x04000000 IHIDDEN - -
0x08000000 ISYSTEM - -

0x10000000 - -
0x20000000 IDIRECTORY used
0x40000000 IARCHIVE -
0x80000000 INEWNAME -

the implementation is straight forward, except
for the fact that the attributes have to be mapped
to match with the ext2 ones to avoid a separate
tool for manipulating them (this could be avoided
when using a separate flag field in the on-disk
representation, but the overhead is minimal)

a special jfs_ioctl is added to allow for the new
JFS_IOC_GETFLAGS and JFS_IOC_SETFLAGS calls.

a helper function jfs_set_inode_flags() to transfer
the flags from the on-disk version to the inode

minor changes to allow flag inheritance on inode
creation, as well as a cleanup of the on-disk
flags (including the new ones)

beforementioned helper to map between ext2 and jfs
versions of the new flags ...

the JFS_SECRM_FL and JFS_UNRM_FL are not done yet
and I'm not 100% sure they are worth the effort,
the rest seems to work out of the box ...

JFS: Add back directory i_size calculations for legacy partitions

Linux-formatted jfs partitions have a different idea about what i_size
represents than partitions formatted on OS/2. The i_size calculation is
now based on the size of the directory index. For legacy partitions, which
have no directory index, the i_size is never being updated.

This patch adds back the original i_size calculations for legacy partitions.
