d220f477ed wscript: drop unused "mandatory variables" 'top' and 'out' in libs
Variables by these names are only used from the local wscript and when
running "waf configure", which already for other reasons only can run at
the top-level.

These variables are thus not mandatory and not used.

7737c17d52 wscript: drop unused imports, scripted
Done with ad hoc scripting hacks processing unused imports found by pyflakes:

for f in $( find * -name wscript ); do echo; pyflakes $f; done | grep 'waflib.Logs.* but unused' | cut -d: -f1 | while read f; do sed -i 's/^import waflib.Logs as Logs,/import/g' $f; done
for f in $( find * -name wscript ); do echo; pyflakes $f; done | grep 'waflib.Options.* but unused' | cut -d: -f1 | while read f; do sed -i 's/import waflib.Options as Options, /import /g' $f; done
for f in $( find * -name wscript ); do echo; pyflakes $f; done | grep 'waflib.Options.* but unused' | cut -d: -f1 | while read f; do sed -i 's/^from waflib import Options,/from waflib import/g' $f; done
for f in $( find * -name wscript ); do echo; pyflakes $f; done | grep ' imported but unused$' | sed "s/^\([^:]*\):[0-9]*:[0-9]* '\(.*\)'.*/\1 \2/g" | while read f lib; do sed -i "/^import $lib$/d" $f; done
for f in $( find * -name wscript ); do echo; pyflakes $f; done | grep 'waflib.Options.* but unused' | cut -d: -f1 | while read f; do sed -i '/from waflib import Options$/d' $f; done
for f in $( find * -name wscript ); do echo; pyflakes $f; done | grep 'waflib.TaskGen.* but unused' | cut -d: -f1 | while read f; do sed -i '/from waflib import TaskGen$/d' $f; done
for f in $( find * -name wscript ); do echo; pyflakes $f; done | grep 'waflib.Task.Task.* but unused' | cut -d: -f1 | while read f; do sed -i '/^from waflib.Task import Task$/d' $f; done
for f in $( find * -name wscript ); do echo; pyflakes $f; done | grep 'waflib.Tools.winres.* but unused' | cut -d: -f1 | while read f; do sed -i '/^from waflib.Tools import winres$/d' $f; done
for f in $( find * -name wscript ); do echo; pyflakes $f; done | grep 'waflib.Utils.* but unused' | cut -d: -f1 | while read f; do sed -i '/^import waflib.Utils as Utils$/d' $f; done

3c857a78c6 JACK backend: serialize all jack server calls with a mutex
As was noted in 88ee3af3ea it is unsafe/undefined behavior if two threads
sleep on the JACK request file descriptor, since there is no way to control
which one will wake and process the request. Since each thread may have
sent a different request, this can lead to a thread misinterpreting the
response because it is reading the wrong response.

This may (or may not) solve some subtle problems with JACK, but was
revealed by having a control surface (LaunchPad Pro) that registers
three ports from the butler thread at about the same as the GUI
thread is registering the auditioner. One thread read the wrong
response, and because of some slightly weird code/design, it attempts
to rename the port from within the response handler, which in JACK1
leads to deadlock (and later, zombification).

88ee3af3ea JACK backend: add a mutex to serialize per-thread port register requests to server
Without this, two threads can both sleep on the same communication channel, and the wake order
is non-determinate, so the wrong thread may process the response to the other thread's request.

Windows: unconditionally request high timer resolution
Previously timeBeginPeriod() was only called when MIDI
system was set to WinMME. It was also possible that
it was never unset in case starting the engine failed.

This significantly speeds up freewheel export which uses
Glib::usleep(100) when MIDI is disabled.

Fix setting pretty-names when engine is restarted
port-meta-data depends on the audioengine backend/device
settings. Those are only available after the engine is started,
not from within the backend's _start() method.

This is is only relevant for callback based backends.

Backends with a blocking process thread explicitly emit
port-manager callbacks there before entering the main loop.

0eed821eb9 JACK: do not set the thread-init callback
Because we use the non-callback API, we can call our thread init callback
ourselves from ::process_thread(). In addition, the init_callback in JACK is
used by every thread JACK creates, including the messagebuffer thread, and this
confuses things from an Ardour POV where the callback was intended just for
realtime threads.

ALSA: use dedicated device reservation for probing
It can happen that the main AlsaAudioBackend::_device_reservation
is still busy while I/O devices are set. In this case a
dedicated AlsaDeviceReservation needs to be used which can fail
silently.

A common example is disconnecting a USB device while it is in
use. The Halted signal can show the session dialog, which calls
set_input_device_name before the device reservation of the
unplugged device terminated.

ALSA: fix autostart when using different I/O devices
ALSA backend modified the internal state when different devices
were used, re-assigning one (usually input-device) to "None"
when it's resampled. This lead to EngineHints not matching the
EngineState, and autostart was disabled, and a dialog
"Engine I/O device has changed since you last opened this session."

PulseAudio: use correct casing
This will also change the internal backend name, so it will miss the
previous 'config' setting '<State backend="Pulseaudio" ...'` and the
session file's '<EngineHints backend="Pulseaudio" ...'. But that is no
big deal after upgrading. Especially after the backend has been broken
for some users for a while.
