[PATCH] Reworked patch for labels on user space messages

The below patch should be applied after the inode and ipc sid patches.
This patch is a reworking of Tim's patch that has been updated to match
the inode and ipc patches since its similar.

[updated:
>  Stephen Smalley also wanted to change a variable from isec to tsec in the
>  user sid patch.                                                              ]
