Since barriers are axis-aligned, we can do the intersection test with
simple interpolation rather than line-segment intersection. This also
helps us out in the future when we want the barriers to extend to be
rays and lines rather than just segments.

Pointers (and the hands that drive them) aren't very precise, and the

In order to send events to specific windows associated with the barrier,
we need to move the code that handles barriers to somewhere where it's
easier to construct and send events. Rather than duplicating XSync with
its XSyncSelectAlarm, re-use the existing XI infrastructure.
For now, just move a bunch of code over, rename some things, and initialize
the new structures, but still consider it a separate codebase. Pointer barrier
requests are still handled by XFixes, so this is a weird intermediate state.
It's unknown whether we'll add explicit requests to pointer barriers inside
XI.

Given the following scenario:

3) client C selects for TouchBegin on window W with device E
Step 3 will fail with BadImplementation, because attempting to look up
XIAllDevices or XIAllMasterDevices with dixLookupDevices doesn't work.
This should succeed (or, if it was selecting for device D, fail with
BadAccess as it would be a duplicate selection).
