Fix endless poll on macOS #8753
...
Harvid daemonizes and does not write anything
to stdout/err. as opposed to select(), poll() on
macOS does not return when the child process
terminates or is killed.
However poll() on an invalid FD does throw an
error and POLLNVAL is set.

Micro-optimization: std::atomic<> vs glib
...
glib atomic operations include a complete act as a full
compiler and (where appropriate) hardware memory barrier.
std::atomic<> allows dedicated acquire and release barrier
semantics which are not available with glib.

Do not use named semaphores on Windows since they are system wide
...
https://docs.microsoft.com/en-us/dotnet/standard/threading/semaphore-and-semaphoreslim#named-semaphores
Running multiple instances of Ardour or Ardour/Mixbus would fail in very
odd ways since they would signal each other. Unnamed sems are
correct for this use case.

Fix window process thread priorities
...
While POSIX defines a single contiguous range of numbers that
determine a thread's priority. Win32 defines priority classes
and priority levels relative to these classes.
pthread maps those to -15 .. +15 with the top six ones
corresponding to REALTIME_PRIORITY_CLASS and max being
THREAD_PRIORITY_TIME_CRITICAL
Note that the PA backend can USE_MMCSS_THREAD_PRIORITIES
and PBD::MMCSS::set_thread_characteristics() directly for
the I/O threads.

Fix incorrect port lists due to custom sort
...
Previously the following were treated as equal
"MIDI_foo" == "MIDI bar"
So std::map<> PortManager::_ports and PortEngineSharedImpl:_ports
could only have either. This resulted in missing ports
and missing calls to existing ports in cycle_start().
This mainly affected MIDI tracks with imported files, since there
is "MIDI Clock in", and imported files result in tracks
"MIDI_file-name".
This issue was introduced in 6.6-200-g60ff3ef764

use poll(2) rather than select(2) for reading output from an exec'ed process
...
select(2) can only handle file descriptors up to 1024, and there are fairly easy to reproduce
cases where the file descriptor used here is larger than that.

Do not move automation when inserting regions

RegionInsertDrag or Consolidate Range or any other operation
calling Playlist::add_region() previously triggered RangesMoved()
which resulted in DiskReader::move_processor_automation()
NB. insert + ripple still moves automation correctly.
