103ef2ba08 introduced an API to write raw data (const void*)
to a child process, along with the previous API to
write (std::string const&)
VideoMonitor uses write_to_stdin("fixed text"), and g++
interprets this to use the (const void*) API instead
of the std::string, which breaks communication.
It's a well established convention that pan y-axis automation,
or vertical uses (top) +1 for left.
This special cases rotary knobs (and horizontal sliders) to retain
a clockwise movement (or movement to the right) for panning to the
right.
There are still over a hundred left, but this addresses many already.
In particular @param references to undocumented parameters.
Most notably in audio_backend.h
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&)’
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.

and video in order to keep the legible
