No touch events while utouch-grail clients wait for next timeout

[Daniel d'Andrada]

Steps to reproduce the issue:
1 - Have a utouch-geis client running with a Drag subscription for N touches.
2 - Swipe N fingers over your mulitouch device.

Expected outcome:
There's a steady flow of touch events coming through

Actual outcome:
A handful of events come, then there's a pause of some hundreds of milliseconds, and then events continue flowing, including a burst with all events that should have come during that pause.

What happens is that when XSyncAwait() is called for grail_next_timeout() (which will return the drag gesture timeout), it will make XSync wait until that timeout is reached. Using an XSyncAlarm instead of XSyncAwait() would solve that issue.
