Optimize buffer zero-filling 2019-02-06 17:02:20 +01:00

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.

497a3fbaa1 Fix --no-nls (2/5), prefer #if in libs 
This is for consistency with system-wide gettext.h which is used
by some 3rd party libs. system-wide gettext uses `#if ENABLE_NLS`,
not #ifdef

bcdb3aec3a Check in a few MSVC projects to accommodate the change from libtimecode to libtemporal 
This is mostly to see if there'll be any problems when merging these changes into Mixbus. I'm guessing there'll be some conflicts in these projects (and a lot more to follow...)

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.

e91b80eb85 Centralize control-parameter math functions in libpbd. 
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.

333e20a3a6 VCA/SlavableAutomationCtrl re-design: 
* 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)

1f094027c5 Remove normalization of property names from libpbd xml code 
It may have been OK to add this code temporarily at this low level, but as it
was introduced in 2008, this change is made with the assumption that any
Sessions that were affected have been re-saved since then with corrected
property names and that "normalization" is no longer necessary.
