I've been playing with this some more and it turns out your patch works. The
problem was I didn't clean git repositories before compiling. Because of that
every time I started weston it started from the very first folder I compiled
to, and that one didn't have patch applied. I always started event-debug from
the right folder and that's why it reported two button presses but client only
registered one.

Also, DEFAULT_TAP_TIMEOUT_PERIOD should be reduced to 150 ms (or maybe 140?).
When I was using gedit some double taps didn't get registered. That happened
when I tapped slower so I guess those taps exceeded the time required by the
application. That happened with DEFAULT_TAP_TIMEOUT_PERIOD set to 180. When I
reduced it to 150 it always worked. And with smaller timeout period there's
also smaller delay between lifting finger for the second time and that getting
registered as a second tap. With timeout period set to 150 I could still
reliably do tap and drag. I haven't tried anything smaller than 150, but i
think it would work with 140. I'll try that tomorrow.
