hannken fcd5ec4841 When using a snapshot take the snapshot raw device on further open.
Fixes PR #34923  dump(8) only dumps a corefile with -X (snapshots)

perseant 1c57171fe3 Change LFCNWRAP{STOP,GO} to make them more suitable for snapshotting; in
particular, the caller can now choose whether to wait for the condition
to be met, and if the caller of LFCNWRAPSTOP dies or otherwise closes
the descriptor, the filesystem is started again.  Updated the ckckp
regression test to use the new semantics.

dump_lfs(8) now uses the fcntls to implement LFS-style snapshotting through
the -X flag, addressing PR#33457 albeit not using fss(4).  Fixed a couple
other problems with dump_lfs that manifested themselves during testing.

hannken 1f51c28099 Snapshot support for dump(8):
- New option `-x backup' takes the dump from a snapshot backed up by `backup'.
  The snapshot will be deleted on exit.

- New option `-X' as a synonym for `-x mountpoint' where `mountpoint' is the
  file system to be dumped.

hannken 8c21bc6224 Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
    may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
    Snapshots may not be opened for writing and the attributes are read-only.
    Use the mtime as the time this snapshot was taken.
    Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
  one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
  a vnode.
- Add snapshot support to ls, fsck_ffs and dump.

tls 539a3fbb0a The sysctl returning the amount of memory in the system returns "int",
which is silly.  Luckily, it really does return the correct result if
interpreted as an unsigned int.  This change lets dump work on 32-bit
systems that have more than 2GB of RAM.

This commit does not yet include the code to manipulate the extended
storage (for e.g. ACLs), this will be done later.

Don't install "setgid tty", and remove now unnecessary gid/egid swapping.
Remove utmp trawling code pulled in from usr.bin/who.
The Code is now simpler, and more portable (without the utmp cruft) too.
