Switch the default WARNS level for sbin/ to 6.

Submitted by: Ulrich Spörlein

Initialize "he" in DoFile, so savecore(8) is WARNS=6 clean.
Bump WARNS accordingly.

style.Makefile(5):
Use WARNS?= instead of WARNS=.

Style.

- 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

Duh, savecore is called savecore.

Savecore:

Commandline compatible with the previous savecore unless you specify
any options, none of them are implemented (yet).

Scans all devices marked "dump" or "swap" for dump header signatures
and saves dumps off under a name which is a MD5 hash of the header
information. This should give unique filenames. A *.info file contains
ascii version of the header information.

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

* 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

Convert to our man installation style. Also fixed long-standing bug
in `fastboot'/`fasthalt' in which the interpreter would hang around
after `reboot' or `halt' is run, causing an irritating ``Killed'' message.
