Implement -m option to savecore(8) that allows to limit number of kernel
dumps stored. Once the limit is reached it restarts from 0.

- When checking if a dump exists on the given device there is no need to
provide dump directory. Eliminate this redundant argument. This changes
the usage, but the only risk here is that a warning will be printed
about directory given as device.

- Update usage of -C option.

- When clearing dump header from the given device there is also no need to
provide dump directory, although additional arguments for -c were not
documented.

- Document that -v can be used with -c and that list of devices can be given.

Fix a silly little typo I just spotted.

Allow a forced dump even if the dump header information is inconsistent.
Output more verbosity with additional -v's.

Add a flag that reports the existence of a dump, and does nothing else.

The immediate purpose for this option is to use it in rc.d so that we
can make savecore behavior conditional.

mdoc(7) police: nits.

- revert back to vmcore.#
- reimplement -z
- use syslog()
- improve consistancy of messages
- allow -f to recover cleared dumps
- return bufsize to 1024 * 1024
- return the ability to write sparse files
- update man page
- fix minfree to require 2k for info file instead of the kernel size
- include Berkeley copyright too due to amount of old code copied

Add a Xref to dumpon.

mdoc(7) police: restore the correct sorting of SEE ALSO.

* Switch from doing compress(1)ed crashdumps with the -z flag to using
gzip(1). gdb doesn't understand these, but then again it didn't
understand compressed crashdumps either.
* Change a stray lseek() into a Lseek()
* Remove the extraneous prototype for log() which has apparently never
existed in FreeBSD's sources

$Id$ -> $FreeBSD$

Correct use of .Nm, add rcsid, remove unused #include.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Make the savecore command work like the man page says:
- make minfree work by getting the dump size before checking to see
if the dump will fit on the filesystem
- also fail to dump if no minfree is specified but there are not enough
free blocks.

Fix a typo in the man page.

Get rid of _PATH_UNIX completely; use getbootfile(3) instead.

DANGER WILL ROBINSON!
_PATH_UNIX is currently defined as the literal string "don't use this".
I am of two minds about this myself, but wanted to get something into the
tree as quickly as possible.

Converted 'vmunix' to 'kernel'.
