467c801ce8 Abstract definition of rt-scheduler policy
pthread-w32 does not support pthread_setschedparam() with
SCHED_FIFO and bails out. While pthread_create() simply ignores the policy
and sets the priority regadless.

This only affects ctrl-surface event-loops & AutomationWatch on Windows.

6968c9f909 Drain ALSA raw-midi buffers after 64 bytes
Very long sequence of *concurrent* events may otherwise be truncated
because the backend requests a buffer-size of 64 bytes via
snd_rawmidi_params_set_buffer_size().

f9db9bf5fd Retain order of concurrent MIDI events
This fixes an issue with FaderPort8 (and maybe other surfaces or synths).

ac923be7af fix port-sort order for good.
TODO find out how to make std::set::find() work with custom sort order,
as std::find may only be O(N) and not O(log (N)).

ba78359129 prepare for update to waf 1.8
uselib is no longer implicit (inherited by .use). This is still incomplete,
some uselibs for non-linux variants may be missing.

bld.is_defined("HAVE_XXX") also no longer works and will have to be
changed (I think to bld.env["HAVE_XXX"]) in countless places.

dcf327f86a Return meaningful error codes when ALSA backend fails to start
Unfortunately it seems that in zita-alsa-pcmi doesn't set state() correctly in
some cases. Setting an invalid SR doesn't display the correct error message,
first guess would be that set_hwpar is failing and state() is not
representative of the actual error.

09dd3fc369 some backends can handle incorrectly ordered midi events.
(that can happen if multiple sources send to the same
ouput port, in particular async midi events)
