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.

e9be313c11 Fix latency compensation for audio data in portaudio backend
For drivers that correctly report latency values(ASIO) this should result a
much closer alignment of audio in a loopback test. Measurement and
adjustment may still be needed, especially for non-ASIO drivers.

Testing with the RME HDSP Multiface and Yamaha AG06 using ASIO drivers results
in maximum offset of a couple of samples.

ac301b998a Use a range of values for ASIO buffer sizes if provided by driver
This has been tested on four devices:

- A RME HDSP Multiface
- A Yamaha AG06
- A Focusrite 2i2
- A built-in soundcard running ASIO4ALL

The HDSP and the AG06 only return one buffer size when queried so the preferred
size is used as before.

The Focusrite returns a min corresponding to the position of the slider in the
control dialog and the max is 1024. The granularity is 1 so this means that the
number of values needs to be reduced for the current UI design with a combo
box so the granularity is increased until there are around 8-9 buffer sizes to
choose from evenly spaced between min and max(but we could easily change this
if the UI changes etc).

The ASIO4ALL driver returns a min of 64 and a max of 2048 and a granularity of
8. So where the minimum buffer size and granularity is a power of 2 use only
buffer sizes that are power of 2.

If the driver returns different values for min and max it is not currently
possible to indicate which is the driver preferred value. A checkbox or other
UI element could be added to the AudioSetup dialog to only use the preferred
value but that is more work and perhaps not necessary.

f1b336b01e Add support for callback API to portaudio backend but keep blocking API as default
Don't use the callback API for now until further and wider testing.

4ebc6ef0b4 Fix WinMME midi driver shutdown with sysex enabled
midiInReset triggers the sysex callback to tell the application that it has
finished with the buffer. Calling midiInAddBuffer results in an infinite loop
so just return during shutdown.

f178152114 Use portaudio error codes in the PortaudioIO class.
Having error codes defined in PortaudioIO means it is not dependent on the
ErrorCodes in AudioBackend but it doesn't really make sense to have another
set, so just use the PA ones until they become insufficient.
