4ebcef53f8 Relax max MIDI msg size to 256 (for long sysex)
(win-mme already used 256, CoreMIDI can handle up to 256 as can ALSA)

ab3889fff8 Propagate Latency to backend/system ports
Set accumulated capture-latency for physical-outputs
and accumulated playback-latency for physical-inputs
after Ardour is done setting all non-physical port latencies.

This will be needed for latency-compensation of the complete graph.

30b087ab3d globally change all use of "frame" to refer to audio into "sample".
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode
and video in order to keep the legible

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().

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.
