d382b756c2 Follow up d8ae3fd 
Depending on implementation, d8ae3fd may only construct the spinlock
once to `sl_init`. Later it is only copy-constructed and that leads to
compile and/or runtmime errors.

e.g. gcc-8.3 fails to compile
error: use of deleted function ‘boost::detail::spinlock::spinlock(const boost::detail::spinlock&)’

d8ae3fd3a6 MSVC requires an already initialized object to initialize our boost::detail::spinlock (rather than the simpler #define) 
Hopefully this'll work for the other builds too.

087fd57d37 Re-add Controllable registry 
To facilitate a central registry with weak/shared pointer lookup,
  enable_shared_from_this<ARDOUR::AutomationControl>
was migrated to
  enable_shared_from_this<PBD::Controllable>

The main (and only) user is generic-midi surface's state interface :(

3c96ba1de6 Allow reading future data without read-commit 
This is in preparation for de-click, fade-out. A disk-reader
can keep going, reading buffered data (if any) without changing the
read-index.

6975b5ca54 Prepare buffer for seeking 
Keep track of safe reservation:
Data has been read (or was skipped) previously can be read again
up to the allocated "reservation" (which is never overwritten).

007c4ffdc0 Towards a new disk-reader ringbuffer 
This is mainly a NO-OP, introducing a new PlaybackBuffer type
and preparing for its use.

At this point in time, the buffer is just a power-of-two sized
ringbuffer and the disk-reader's read-logic is still unchanged.

Eventually the read and write sample position that are currently
private to the disk-reader can be migrated to be owned by the buffer.
Also Diskreader::read() positions can be matched to read-position ..
+/- buffer reservation and de-click can read w/o committing the read.

467c801ce8 Abstract definition of rt-scheduler policy 
pthread-w32 does not support pthread_setschedparam() with
SCHED_FIFO and bails out. While pthread_create() simply ignores the policy
and sets the priority regadless.

This only affects ctrl-surface event-loops & AutomationWatch on Windows.
