ffs_snapshot_read(): Allow the kernel to read beyond file system size.
Persistent snapshots work again.
Should fix PR kern/37425: fss_snapshot_mount panic during fsck.
When rc scripts are started from interactive shell, be nice and when user
tries to start an unconfigured service, point him to rc.conf(5) and tell
him about the one* keyword. Also be more user friendly when an unknown
argument is entered.
Example:
# /etc/rc.d/cron start
$cron is not enabled - see rc.conf(5).
Use the following if you wish to perform the operation:
/etc/rc.d/cron onestart
# /etc/rc.d/cron nonsense
/etc/rc.d/cron: unknown directive 'nonsense'.
Usage: /etc/rc.d/cron [fast|force|one](start stop restart rcvar status poll)

Reminded about it and reviewed by <lukem>
snapshot use. Adjust ffs_blkfree_common to get the fs instance passed
in, the original commit didn't account blocks in the snapshots
correctly. Assert that ffs_blkfree is used with the primary fs instance
and that ffs_checkfreefile is only used for snapshots. Move the bdwrite
from ffs_blkfree_common into the caller for symmetry. This creates a
redundant write of unmodified data for ffs_blkfree_snap if a double free
of a block happens.

- Output a .bss section and make all the symbols relative to it, instead
of making them absolute.
- Output a single load section, no need for two.
'gdb /dev/ksyms' still doesn't work because ksyms doesn't do mmap yet.
specific set of user-derived variables, to be used in SOURCEMODE.
- In SOURCEMODE, generate the rc.d scripts xdm and xfs.
- Auto-detect if X11 sets are used (either through the value of MKX11 in
SOURCEMODE, or by finding an xetc-xpecific file in sets mode).
- Ignore X11-specific rc.d scripts if X11 is not used.
