Emit Signal when MCSS Threads are exhausted
...
By default Windows has limit of 32 MMCSS threads.
Ardour uses MMCSS scheduling for for hardware I/O (audio and MIDI)
as well as for realtime process threads, and a user on a
recent machine may run into this limit.

Add API to query max MMCSS threads on Windows
...
By default Windows limits the number of MMCSS threads to 32.
This can cause problems on modern systems with >= 32 cores,
when Ardour uses many process and I/O threads.
So far this is just a first step (query API)

Avoid using 'boost::aligned_storage' which is known to be problematic in MSVC builds
...
MS initially believed the runtime issues might be fixable in VS2015 but in fact, Boost's alignment strategy and Microsoft's alignment strategy just turned out to be incompatible:-

rework PBD::Signal emission code to avoid memory allocation
...
We now use a stack allocator when making a copy of current connection state at
the start of the signal emission process, and when collecting results from
signal handlers in the case of a non-void return type.
These changes also include a functionally neutral reworking of how the connection
state copy is made and then used to check that a connection/handler is still
valid mid-emission.
Heap allocation will still happen if a signal has more than (currently) 512
connections. A little experimentation reveals that the maximum number of
connections is typically nroutes+1, so 512 seems like a reasonable choice
for this.
