caching in configure

-----BEGIN PGP SIGNED MESSAGE-----
This patch fixes caching in configure.
Currently the "broken signed to unsigned casting" check isn't actually
cached, though there is an attempt at it -- the problem is that the
cache parameter name must include _cv_, as config.cache is generated
using `set`, with a grep for _cv_. (This system has the advantage that
parameters in the cache that we don't know about will be preserved.)
I changed the name to one including _cv_.
The pathnames of signal.h, utmp and wtmp are currently not cached
at all. I added caching. This is particularly helpful on systems
where the configure check gets these paths wrong, as they only need to
be changed manually once -- thereafter the cached value will be used,
without regenerating the incorrect paths.
I also changed many of the cache parameter names to match autoconf
standards.
