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.

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.

Remove unused #include<> (2/2) 
PBD::stacktrace() is not used nor needed by default.
It should be used sparingly.

JACK backend allows to calibrate latency 
However, if jackd is running, we should test if jackd is using
a full-duplex device to establish if latency calibration is
possible -- fix 92f54b3e98.

Remove ambiguous API implementation 
* PortEngine::available() implementation
* AudioEngine::connected() wrapper

Eventually we may re-introduce PortEngine::available along
with a libardour internal port-engine.

2a89234027 move control app launching back into audio backend to allow ASIO/CoreAudio model to work; push initial state of AMS dialog to backend 
Issues remain with the basic model of the AMS dialog - when is
newly chosen state pushed into the backend (which can then
modify the control app button sensitivity. This is a special
problem for this button because APIs like ASIO and CoreAudio
probably don't allow us to launch a control app for an arbitrary
device, but only one actually in use. In this sense it is
different from properties like available buffer size etc, where
we can typically query without actually using the device.
