Add '-u' switch that would uncompress cores that were compressed by
kernel during dump time.

A real life scenario is that cores are compressed to reduce
size of dumpon partition, but we either don't care about space
in the /var/crash or we have a filesystem level compression of
/var/crash. And we want cores to be uncompressed in /var/crash
because we'd like to instantily read them with kgdb. In this
case we want kernel to write cores compressed, but savecore(1)
write them uncompressed.

Upgrade libxo to 0.4.5.

Local changes incorporated by 0.4.5: r284340
Local changes retained: r276260, r282117

Obtained from: https://github.com/Juniper/libxo

Convert savecore to libxo. The 'verbose' paths still use printf since they're
meant for interactivity on the command line and contain a lot of redundant
information.

Convert sbin/ to LIBADD
Reduce overlinking

Switch the default WARNS level for sbin/ to 6.

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

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

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.
