Summary:                    [patch] Failure to include semaphore.h breaks
compilation with >2.6.34 kernels (2.6.35-rc0)
Description: 
DAHDI relied on other headers to drag in semaphore.h, this is no longer the
case since:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3142788b7967ccfd2f1813ee9e11aeb1e1cf7de2

The result is:
In file included from
/var/tmp/portage/net-misc/dahdi-2.3.0/work/dahdi-linux-2.3.0/drivers/dahdi/voicebus/GpakApi.c:36:
/var/tmp/portage/net-misc/dahdi-2.3.0/work/dahdi-linux-2.3.0/drivers/dahdi/voicebus/GpakCust.h:114:
error: field ‘sem’ has incomplete type

Patching the header to include semaphore.h as it should always have done
will not hurt older kernels.
