[PATCH 1/9] Udev integration: Configure and Makefile changes for udev patches

[Peter Rajnoha <prajnoha@redhat.com>]

Hi,

I'm sending a whole patchset again for sure, because some of the
patches are updated...

I've added these configuration options:

--disable-wait-for-udev 
(disables the wait, no semaphores, the macro to check is
WAITFORUDEV_SUPPORT, default is enabled)

--with-udev-prefix=DIR
(sets the prefix for the location where the rules will be installed,
this is basically [udev_prefix]/lib/udev/rules.d, where
udev_prefix=${exec_prefix} by default -- this is useful if someone
uses his own compilation of udevd where this is defined exactly like
this, so the location could be 'synchronized' this way)

When the wait-for-udev is enabled, the check for sys/ipc.h and sys/sem.h
is used as well.

Peter
