The primary usecase of grail involves using it together with the
xserver, which is not threaded. Revert the touch-dev code back to
the state prior to adding the threaded processing. Deferred event
handling can be implemented by other means when needed.

Add grail_get_units() to the api, so so that applications can

The bitmask passed to get_clients takes the number of bytes
in the bitmask as argument, not the number of types, as easily
assumed given the argument name. This patch changes the name
to type_bytes to avoid confusion.

In order to enable deferred events from grail, but the event
processing in a separate thread, and have the calling thread return
as quickly as possible.

The aim of this first commit is to get down to hard testing of concepts,
and the library currently has two test programs, touch and grail,
which can be run on commandline. Touch tests the touch interface,
and grail tests the gesture interface.
Expect thinking errors and some glitches. Other than that, the code
runs fine.
