Unbreak protocol ABI for XIAllowEvents - inputproto 2.1.99.6inputproto-2.1.99.6
XIAllowEvents was extended with touchid and grab_window in
2ea2f99f4fe1dcd3b8e539ca41c482fc40a0533d. 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.
