1ab3783e1a mdoc: move CAVEATS, BUGS and SECURITY CONSIDERATIONS sections to the 
bottom of the manpages and order them consistently.

GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

d747431e06 - Move from mount(2) to nmount(2). This should allow to convert MNT_SNAPSHOT 
flag from a mount flag to FS-specific flag.
- Simplify usage. Instead of 'mksnap_ffs /mnt/foo /mnt/foo/snap' allow to
  give only one argument: 'mksnap_ffs /mnt/foo/snap'. Old usage is also
  accepted for now.
- Add an example of how to mount a snapshot.

96f1216abd Make sure we don't pass garbage to the kernel. 
The filesystem is named "ufs" not "ffs".

62316cd3c7 Check that the user running mksnap_ffs has permission to create and 
remove a snapshot file from the directory in which they have requested
to have it made. If they do not have write permission in the directory
or the directory is sticky and not owned by the user, then they
will not be able to remove the snapshot when they are done with it.

af2849b505 Add the mksnap_ffs command to the sbin directory. This setuid root 
program allows users in the operator group to take filesystem
snapshots. Its first use will be in support of `dump -L'.
