Previously Ardour used a /local/ per track vari-speed mechanism.
Now that the disk-reader is a latency-compensated processor, the speed
of each disk-reader would need to be maintained locally, offset by each
disk-reader's output latency. Furthermore each disk-reader may
produce a different number of samples, depending on its global alignment.
This commit introduces port-data resampling directly at the engine-level:
Up/down-sample all input ports at the beginning, and down/up-sample output
port-data using the inverse ratio at the end of the session's process
cycle.
The session itself is unaware of the speed-change, and only needs to
handle transport speeds {-1, 0, +1}.
This also allows for aligned cue-monitoring and vari-speed recording,
and also pitch-shifts synthesized MIDI along.

Paul Davis was responsible for introducing almost all of this.

alignment ... working except that we report the wrong information to JACK and i've noticed a couple of odd circumstances where turning on a latent plugin caused punch recording to fail

Vimmers, try let c_space_errors = 1 in your .vimrc to highlight this kind of stuff in red. I don't know the emacs equivalent...

All #include statements that include a header that is a part of a library
bundled with ardour MUST use quotes, not angle brackets.
Do this:
#include "ardour/types.h"
NOT this:
#include <ardour/types.h>
Rationale:
This is best practice in general, to ensure we include the local version
and not the system version. That quotes mean "local" (in some sense)
and angle brackets mean "system" (in some sense) is a ubiquitous
convention and IIRC right in the C spec somewhere.
More pragmatically, this is required by (my) waf (stuff) for dependencies
to work correctly. That is:
!!! FAILURE TO DO THIS CAN RESULT IN BROKEN BUILDS !!!
Failure to comply is punishable by death by torture. :)
P.S. It's not that dramatic in all cases, but this (in combination with some
GCC flags specific to the include type) is the best way I have found to be
absolutely 100% positive the local ones are being used (and we definitely
want to be absolutely 100% positive on that one).

it is possible that major changes may follow in the near future. it is certainly not complete, but the fundamental changes to Port/Buffer operation merit a commit at this point

Working audio sends/port inserts
Send gain, panning
MIDI sends working (maybe port inserts too?)
Buffer/Port fixes (related to silence)
Metering bug fixes

- Converted vector<Sample*> to BufferList and numerous counts from int to ChanCount (and related changes)
- Added fancy type-generic iterators to BufferList, PortIterator (see IO::collect_input for a good example of the idea - the same code will work to read all input (of various types in a single IO, eg instruments) without modification no matter how many types we add)
- Fixed comparison operator bugs with ChanCount (screwed up metering among other things)
- Moved peak metering into it's own object, and moved most of the pan related code out of IO to panner (still a touch more to be done here for MIDI playback)
Not directly MIDI related fixes for problems in trunk:
- Fixed varispeed gain/pan automation to work properly (was reading the wrong range of automation data, probably causing nasty clicks?)
- Fixed crash on varispeed looping (possibly only a 64-bit problem). It still doesn't work, but at least it doesn't die
Quite a few things broken, and the new classes are pretty filthy still, but I think the direction is a lot better than all my previous plans...

- Added new Port classes, code to drive them
- Added PortList, which is a filthy mess ATM (nevermind that, it's the interface that's important at this stage)
- Added ChanCount, though it isn't very thoroughly used yet. That's the next step....
- Fixed a few bugs relating to loading sessions saved with trunk
- Fixed a few random other bugs
Slowly working towards type agnosticism while keeping all the former code/logic intact is the name of the game here
Warning: Removing ports is currently (intentionally) broken due solely to laziness.
