* Test a sequence of keysyms, resulting from a sequence of key presses,

*
* - Each test runs with a clean state.
* - Each line in the test is made up of:
* + A keycode, given as a KEY_* from linux/input.h.
* + A direction - DOWN for press, UP for release, BOTH for
* immediate press + release, REPEAT to just get the syms.
* + A sequence of keysyms that should result from this keypress.
*
* The vararg format is:
* <KEY_*> <DOWN | UP | BOTH> <XKB_KEY_* (zero or more)> <NEXT | FINISH>
