Havn't managed to completely remove it because of Session loading from XML - the
Diskstreams are separate from the Tracks (I assume as a throwback to when they
were distinct) so the Diskstreams need to be stored somewhere until the Tracks
are loaded. Ideally tracks should completely own their Diskstreams - not sure
how to accomplish this without breaking Session loading though...

unecessary changes. (Sorry, doing a "sprint" based thing, this is the end of the first one)
Achieved MIDI track and bus creation, associated Jack port and diskstream creation, and minimal GUI stuff for creating them. Should be set to start work on actually recording and playing midi to/from disk now.
Relevant (significant) changes:
- Creation of a Buffer class. Base class is type agnostic so things can point to a buffer but not care what kind it is (otherwise it'd be a template). Derived into AudioBuffer and MidiBuffer, with a type tag because checking type is necessary in parts of the code where dynamic_cast wouldn't be wise. Originally I considered this a hack, but passing around a type proved to be a very good solution to all the other problems (below). There is a 1:1 mapping between jack port data types and ardour Buffer types (with a conversion function), but that's easily removed if it ever becomes necessary. Having the type scoped in the Buffer class is maybe not the best spot for it, but whatever (this is proof of concept kinda stuff right now...)
- IO now has a "default" port type (passed to the constructor and stored as a member), used by ensure_io (and similar) to create n ports. IO::register_***_port has a type argument that defaults to the default type if not passed. Rationale: previous IO API is identical, no changes needed to existing code, but path is paved for multiple port types in one IO, which we will need for eg synth plugin inserts, among other things. This is not quite ideal (best would be to only have the two port register functions and have them take a type), but the alternative is a lot of work (namely destroying the 'ensure' functions and everything that uses them) for very little gain. (I am convinced after quite a few tries at the whiteboard that subclassing IO in any way is not a feasible option, look at it's inheritance diagram in Doxygen and you can see why)
- AudioEngine::register_audio_input_port is now register_input_port and takes a type argument. Ditto for output.
- (Most significant change) AudioDiskstream abstracted into Distream, and sibling MidiDiskstream created. Very much still a work in progress, but Diskstream is there to switch references over to (most already are), which is the important part. It is still unclear what the MIDI diskstream's relation to channels is, but I'm pretty sure they will be single channel only (so SMF Type 0) since noone can come up with a reason otherwise.
- MidiTrack creation. Same thing as AudioTrack but with a different default type basically. No big deal here.
- Random cleanups and variable renamings etc. because I have OCD and can't help myself. :)
Known broken: Loading of sessions containing MIDI tracks.

b) added initial "big meter" mode for tranzport
c) fixed some lock issues in ARDOUR::IO objects
d) generic_midi control surface module now compiles and loads
git-svn-id: svn://localhost/trunk/ardour2@450 d708f5d6-7413-0410-9779-e7cbd77b26cf
b) basic support for Frontier Design Tranzport
c) probably broke some aspect of existing generic MIDI feedback
git-svn-id: svn://localhost/trunk/ardour2@441 d708f5d6-7413-0410-9779-e7cbd77b26cf
b) prevent transport motion if stop-at-session-end is true
c) ensure that (more) menu items that provide control over Configuration object options are in the correct state at startup
d) Configuration options removed from "have a session" sensitivity toggling
e) removed functionally empty default_keys.cc
git-svn-id: svn://localhost/trunk/ardour2@433 d708f5d6-7413-0410-9779-e7cbd77b26cf
b) buttons for "restore pending state" dialog had reversed semantics
c) logic for checking a pending source file header was wrong
d) fixed file unlink from within real-time context
git-svn-id: svn://localhost/trunk/ardour2@424 d708f5d6-7413-0410-9779-e7cbd77b26cf
b) separate data format and header format for native audio files
c) expose data/header selections in GUI
d) fix error in file naming for multichannel tape tracks
e) remove blocks on GTK rc files during startup

ARDOUR_GLADE_PATH
ARDOUR_RC
ARDOUR_UI
ARDOUR_UI_RC
ARDOUR_BINDINGS
ARDOUR_COLORS
They have been replaced with just one environment
variable called ARDOUR_PATH which can contain a number
of colon separated paths that are used to find various
configuration and data files. Files located in
ARDOUR_PATH have priority over files in ~/.ardour/ and
in the system path.
Moved two member functions of the Configuration class
into globals.cc as they should of been static and I'm
trying to keep the non-portable code together when it
makes sense.

* Remove debug output preventing compilation on x86_64.
* Build shared libraries for all libs/* when DEVBUILD=1 to fix linking for x86_64/non-x86.
* Simplify/consolidate the dev scripts a bit.
* Export ARDOUR_COLORS variable in dev scripts.
* Remove G_DISABLE_DEPRECATED from glibmm CXXFLAGS to allow compilation with newer versions of glib.
* Build soundtouch with SYSLIBS=1, hopefully we can link to system soundtouch soon.
