6c88f339ca some further invalidation details: 
Prevent double unref during when the EventLoop terminates:
deleting the ringbuffer deletes all requests, some of which may
contain stale invalidation

remove the buffer_map_lock, now that signals ref-count the IR.

a95be76741 rework request invalidation 
This kills 2 birds with 1 stone: Removes the necessity of locks
and makes call_slot() realtime safe (req->invalidation->requests list
push_back). On object destruction, the invalidation-record (IR) itself is
invalidated.

Invalidated IRs are pushed onto a trash-pool and deleted in the event-loop
of the invalidated object (GUI thread) once all requests that reference it
have been processed.

One last detail remains: PBD::signal connect should reference the IR
and disconnect unreference it. This will guarantee that signal emission
will not reference the IR while the pool trash is dropped.

62b06fa427 Add a trash pool for invalidation requests. 
While EventLoop::invalidate_request() does invalidate request in the
request-list. It does *not* invalidate requests in the
per-thread-request-ringbuffer(s).
The invalidation record cannot be deleted in EventLoop::invalidate_request
see 6b5891a78f.

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)

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
