Fix window process thread priorities

corresponding to REALTIME_PRIORITY_CLASS and max being
THREAD_PRIORITY_TIME_CRITICAL
Note that the PA backend can USE_MMCSS_THREAD_PRIORITIES

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

gcc-11 compat, volatile atomic variables (1/2)
...
"While 'atomic' has a volatile qualifier, this is a historical
artifact and the pointer passed to it should not be volatile."
Furthermore "It is very important that all accesses to a
particular integer or pointer be performed using only this API"
(from https://developer.gnome.org/glib/2.68/glib-Atomic-Operations.html )
Hence initialization of atomic variables is changed to also use
this API, instead of directly initializing the value.
This also fixes a few cases where atomic variables were
accessed directly.

RCU: Fix race condition between writer/reader

This uses an atomic counter and spins only on the writer side, which
preserves realtime behavior on the reader side. The spinning yields (by
using the same Boost function from Boost spinlocks) to be
scheduler-friendly.
Fixing this bug also lets us be able to confidently drop garbage early
in the writer if appropriate, so do that and avoid keeping dead wood if
possible.

Moving Controllable::set_interface() into a 'cc' file makes it easier to fix our MSVC build issue (with min + max)

move virtual method requiring std::min from header into .cc

The method is virtual so it could never have been inlined anyway

Partially revert commit #23feb0491e

For MSVC, the 'using std::' statements are needed when building anything which #includes 'pbd/controllable.h' (never quite figured out why...)

Only try using __pthread_get_minstack on glibc
...
This is a glibc-only extension, so don't bother on other platforms.
Also, according to POSIX, PTHREAD_STACK_MIN is defined in limits.h, so
include climits just to be safe.

Offset stack-size by current TLS #8200
...
Some libraries use thread locals and hence increase the min
requirement.
This is seen on void-linux for example:
> linking a minimal program against cairo gives a
> __static_tls_size of 43008 bytes.
> Doing the same on Ubuntu focal and Debian bullseye,
> __static_tls_size is only 4608.

PlaybackBuffer: extend API to include write_ptr()

Add API to PlaybackBuffer to compute amount of data that can overwritten
...
The distance is between a given offset in the buffer (probably a
read position at some point in time) and the write ptr. Any data after
the write ptr is "old" and not readable, and thus not worth overwriting
since we would not read it anyway.

Prevent huge stack allocations for MIDNAM files

xmlParseMemory() uses a c-pointer char*.
Previously MIDNAM data on the heap were wrapped inside
a std::string only to be later accessed via c_str().

Extend FileArchive to import archive entries individually
...
This is needed primarily for a workaround for #7971 . When importing a template
that has been exported on Ardour5 on MacOS we need to fix the paths of the
archive entries.
Later we can use this functionality also to handle imported templates if
templates with the same name already exist.
This commit only adds methods and members to FileArchive, it does not modify
anything to make regressions unlikely. This, however, leads to some duplicated
code. Eventually we should consolidate this a bit.

Some initial changes (currently for libpbd only) to help a new contributer who's trying to build with MSVC2017

These changes compile okay for me (using VS2019) although they wouldn't link to my older-built libraries. Hopefully he'll be okay if he builds everything with the same compiler.

Fix MacOS 10.11 (clang-8.0.0) builds
...
gcc, and recent clang-10 can construct new objects
using references as arguments.
However clang-8 (and MSVC?) do not:
"error: no matching function for call to 'operator new'"
The compiler apparently does not expand the template
class A <-> `A*` vs. `A const&`
for different cases.
