6b5891a78f The threading anecdotes - Episode 7 
When do_request() destroys the receiver object, the receiver will
free the invalidation record. So the IR needs to be removed from the list
before executing the request.

7a1ff7ce8f rework locking (fa07233a, 112fba182) 
For now: use a single lock, which should fix all related crashes.
optimize (with less contended partial locks) if this works.

fa07233a17 mutex 'er up 
Some overzealous locking to track down RequestObject related crashes.

bc0fa4d689 wrongly locked the current event loop's
request_invalidation_lock instead of the invalidation's list lock.

Also Abstract UI is able to delete requests concurrently with with
EventLoop invalidation.
e.g. PortManager::PortRegisteredOrUnregistered  and GlobalPortMatrixWindow
so the lock needs to be exposed.

If this solves various issues, mutexes should to be consolidated
(request_buffer_map_lock + request_invalidation_lock) and be chosen
such that there is as little contention as possible.

c518bc3fb7 when dragging or copying multiple regions, respect position lock style. 
- music-locked regions are moved by drag beat distance
	  (will conform to tempo changes over the drag distance)
	  audio-locked regions are moved by frame distance.

545f5bee87 changes to adapt to modified version of GTK/Quartz which uses only MOD2 for Command, everywhere. 
The default version of GTK2/Quartz uses MOD2+META for keys and MOD2 for scroll, which is
basically insane

0eff7d4a0c Add option to Zoom to Selection on double click 
Currently implemented for Region and Range selections.

The new option is false/off by default to maintain existing behaviour. I'm not
sure it should require another option, perhaps Zoom to Selection should be the
default and accessing the region properties dialog can be via Modifier+double
click, but further changes can be made on user feedback etc.

Related: #7112

a4d8cc2e04 only recalculate MidiRegion start_beats if there is an offset in the 'part-of' ctor. 
- when drag-copying MIDI regions, a partial region ctor is used
	  which can lead to _start_beats being off by a sample.
	  this in turn leads to 7168 happening, but only if magnetic snap
	  is used and the regions are copied as a group.
	  this should fix 7168, but the magnetic snap part is not yet addressed.

d3803c54de Fix a potential deadlock/crash (here tape-track peak-file) 
read_peaks_with_fpp() already holds _lock, build_peaks_from_scratch()
takes the _lock again.

Depending on glib[mm] and the threading lib it may either result in a
deadlock, or with EDEADLK in undefined behavior when a
non-recursive lock is released twice.
