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).

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.

b35518e212 switch from boost::{shared,weak}_ptr to std::{shared,weak}_ptr 
This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.

JACKAudioBackend::join_process_threads: Don’t pass NULL for jack_client_stop_thread 
This is needed for PipeWire’s JACK frontend, which implements this
function and expects the first argument to be non-null.

416ef93635 use a trick to compile JACK/win with new and old headers 
jack/systemdeps.h is jack2-only and contains many
windows-specific typedefs (native windows threads, ptw32 threads, MSVC
special cases etc etc.) which are not present in jack1/shared headers.

66eef257d8 fix jack thread joining 
at the time the graph gets around to takes down 
client threads, the jack-backend’s jack_client has been reset.
But never mind: libjack does not care about it, anyway.
