Avoid potential issues with space or other strangeness by
quoting filenames through the initscripts.

Clarify the different between the common nut-driver portions of
nut-server and the nut-server (upsd) proper.  nut-driver can't
be used without nut-server so there is no compelling reason
to split into a separate package, but the reorganization makes
such a move easier and makes it clear what each bit is for.

While we continue to use a single initscript, it's a properly
procdified one which handles the upsd daemon as a different
instance than the driver instances.  This resolves a race
condition in which upsd and drivers fail to start do to
a degree of interdepedence.

Also properly 'procd'ifies the nut-server initscript.

Use /var/run/nut as statepath and set appropriate owner
and permissions on /var/run/nut in order to avoid pidfile
for nut being world-readable.

With a LuCI app (of which I have one written) ucification makes
sense (and is in fact needed), so ucify the initscripts.

Also, rather than making selection of things to include an image
a matter of selecting compile-time config options, make optional
things into seperate packages that are built in default builds,
and leave selection of what to include or not up to the user
(e.g. using ImageBuilder, or adding packages via opkg).

An older version of nut is in oldpackages. This commit is based on that
package and bumps the version to the latest release along with unifying
the server and client packages. More build options are provided for any
custom configuration but the defaults provide a working client and
server install which only needs a UPS driver. Drivers still build as
individual packages to minimise bloat. SSL support has also been added.
