Unmaintained input drivers deactivated

[Peter Hutterer]

FWIW, I changed configure.ac to always bail out with an error on the following
input drivers:

xf86-input-magellan
xf86-input-calcomp
xf86-input-digitaledge
xf86-input-dmc
xf86-input-elo2300
xf86-input-dynapro
xf86-input-jamstudio
xf86-input-magictouch
xf86-input-palmax
xf86-input-spaceorb
xf86-input-tek4957
xf86-input-ur98

These drivers are unmaintained and have not seen any updates other than build
fixes since their original imports into the X.Org repositories.
This may mean they are perfect. It may also mean nobody actually uses them and
we waste time maintaining them.

The following error message will be displayed.

        **************************************************************
        This driver is unmaintained and will not receive further
        patches. If you have a need for this driver, please file a bug
        on http://bugs.freedesktop.org.
        **************************************************************

If you have a build script that builds this drivers but you dont actually use
them, update your build script.

If you are/have a user of this driver, please let yourself be known. On the
list or on bugzilla. Be prepared to assume some level of maintainership.

Cheers,
