[PATCH 00/11] Allow registering only wakeup or block handler

[Pauli]

From: Pauli Nieminen <ext-pauli.nieminen at nokia.com>

Here is improved version of removing random empty block and wakeup handlers.
First patch breaks the current handler code and extens API. That patch is most
likely to cause problems. Too bad refactoring is hard to split to smaller
patches.

Remaining patches I wanted to keep small and separated to make it easier to
bisect if I caused any regression in any of them. The udev patch will conflict
with previous patches because it does different change to same line.

I hope Mark likes this patch set more than previous try to eliminate extra
functions.

And I have to run combined x11perf -prop with this set and previous set:
ync time adjustment is 0.1203 msecs.

 300000 trep @   0.0896 msec ( 11200.0/sec): GetProperty

About 0.8usec difference only that could be even inside measurement error.
(This actually eliminates a NoopDDA and a random static handler in server that
I run)

Happy New Year!
