XIAllowEvents was extended with touchid and grab_window in
2ea2f99f4f. This extended the size of
the request from 12 to 20 but also broke the ABI. Older server
match the request size exactly, so compiling libXi 1.5 against
inputproto 2.2 and then running it against a pre-XI 2.2 server causes a
BadLength for any XIAllowEvent request.
Add a new request for the new data.

Dependent devices don't send touch events until the interaction is a true
touch interaction (i.e. doesn't just serve to move the pointer). Once that
happens, all touchpoints send touch events exclusively. Pointer movement
restarts once we're down to one touch that controls the pointer again.
For clients listening to touch events in addition to pointer events, this
also means that a two-finger tap looks identical to holding one finger down
and tapping with a second-finger. Both actions will result in short
TouchBegin/TouchEnd sequences for both fingers.
The above is the default behaviour we expect from touchpads, the protocol is
more generically worded to leave more room for drivers to decide when a
touch only controls the pointer and when it doesn't.

Toolkits need to know which touch event emulated a pointer event and which
ones do not. To quote Carlos Garnacho:
GTK+ does client-side windows by default (GdkWindows without a backing X
window), for this to work the toplevel window in the client needs to
select for more events that it wouldn't normally select for in order to
cater for the event masks in such child "windows". This means that
ideally GTK+ should set the touch events mask in the toplevel, and then
find out whether the "window" would receive pointer or touch events for
the sequence emulating the pointer, and perform the emulation itself.

This is too much of a pain, anyone who includes XI headers needs to define
this. And that affects input and output drivers as well as legacy clients
that don't even need the new stuff.
Removing the need for defines would be enough but then the warnings clog up
the output and hide real warnings. Just ditch them and laugh at those that
use an experimental branch and expect it to work.
