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 :(
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).
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.

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.
Functions formerly in ardour/util.h and some more functions.
The main motivation is libevoral which can use libpbd but not libardour.
The eventual goal is to consolidate various different interpolation,
scaling and deflection methods.
* remember master-ctrl value on assignment & save with session
* Control/AutomationCtrl only stores ctrl's own value (w/o master)
* virtual AutomationControl::get_value () -> use SlavableAC method
* MasterRecord uses weak-ptr (fixes recursive ~Controllable() deadlock)
This is theoretically dangerous, because a PBD::ID is supposed to be unique, and this new constructor
cannot guarantee that. However, the same danger already exists with the std::string-based constructor
All uses of this function have now been replaced by PBD::to_string() from
pbd/string_convert.h
Remove this function so that it isn't mistakenly used to perform numeric to
string conversion when the result is being used for serialization as that only
works if the global C++ locale is set with LC_NUMERIC=C, which is the case
currently but may not be in the future.
