92bcddb437 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.

5ffc3aa28b Use PBD namespace for free CPU functions 
Ideally never put methods in the global namespace
to prevent potential conflicts.

b1d5f065db 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)

b795d36cd3 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:-

d285ff365e Add a visibility specifier that's now needed

ebda6bf0c5 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.

This reverts commit 32ff87f7f6.

This causes issues on macOS/clang
```
../libs/pbd/pbd/stack_allocator.h:152:53: note: destructor of 'StackAllocator<std::__tree_node<std::__value_type<ARDOUR::DataType, std::map<unsigned int, unsigned int, std::less<unsigned int>, PBD::StackAllocator<std::pair<const unsigned int, unsigned int>, 16>>>, void *>, 2>' is implicitly deleted because field '_buf' has a deleted destructor

that *doesn't* apply for at all.

74c4ca3e52 Reduce reliance on boost - the hard part 
the rest from `tools/convert_boost.sh`.

* replace boost::function, boost::bind with std::function and std::bind.

some static_casts<>, and boost::function::clear -> = {}.
