Introduce a new format for the automatically generated version field.

By extending it to a mandatory 8 digits and padding it with zeroes on the
right side it should be possible to avoid problems with version numbers
changing format.
This means  1.19.5->1.20 should be handled correctly now.

Add support for the new subsys.conf keyword (defalt/nodefault).

Flesh out the auto_rel function to help with release notes maintenance.
Added a relnotes.template.irix and make newpkg install a copy
into new sandboxes.
Also clean up newpkg a bit.

Fix a problem with the fix_man function and how to locate the man pages.
The problem was discoved when building gcc-3.4.1 into
$prefix=/usr/local/gcc-3.4.1 and still needing $topinstalldir
to be /usr/local. We now attempt to find any extra subdirs
needed by comparing $prefix and $topinstalldir.
