fixes possible x-talk 1 in, >= 2 out tracks:
Previously, only the first route-buffer of the input buffers
were marked as non-silent in Route::process_output_buffers().
Other buffers in the set (e.g. post-panner) would
contain audio but not marked as non-silent.
* forward midi-data around plugins that have no MIDI-out
* allow to insert plugins with no MIDI-input at a point with one MIDI-channel
This works because excess ports (both plugin and route) remain
unconnected and use scratch-buffers.
Tested with LV2, LXVST and LADSPA.
(AU plugins with variable in/out retain the old behavior, no bypass)

It's slightly possible that this causes trivial build failures on different
configurations, but otherwise shouldn't cause any problems (i.e. no actual
changes other than include/naming/namespace stuff). I deliberately avoided
removing libardour-config.h since this can mysteriously break things, though a
few of those do seem to be unnecessary.
This commit only targets includes of ardour/*.h. There is also a very large
number of unnecessary includes of stuff in gtk2_ardour; tackling that should
also give a big improvement in build time when things are modified.

the passed-in buffers valid. In the case where the main outs delivery is the last
processor in a route, this is not necessary (and wasteful). If another processor
(e.g. a meter) follows the main outs, the passed-in (scratch) buffers must be valid
or the meter will get garbage data.
Fixes meters displaying phantom signals in some cases.

LOADING 2.X SESSIONS WITH THIS COMMIT IN PLACE WILL (PROBABLY) CORRUPT THE .ardour FILE,
MAKING THE SESSION UNLOADABLE ON 2.X AND LOSING INFORMATION.
So don't do that unless you make a backup of the session file first.

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...

And lo, upon the revision of our hoarde 5061, was the last Big Feature
committed to Three Poino, who, now more than ever, lurks imposingly on
the sidelines, heir to the throne, and eventual ruler of the realm.
His eventual succession all but guaranteed, only time and the number
of heads that must roll remain mysteries.

The vast majority of Route signal processing is now simply in the list of
processors. There are definitely regressions here, but there's also
a lot of things fixed. It's far too much work to let diverge anymore
regardless, so here it is.
The basic model is: A route has a fixed set of input channels (matching
its JACK input ports and diskstream). The first processor takes this
as input. The next processor is configured using the first processor's
output as input, and is allowed to choose whatever output it wants
given that input... and so on, and so on. Finally, the last processor's
requested output is used to set up the panner and create whatever Jack
ports are needed to output the data.
All 'special' internal processors (meter, fader, amp, insert, send) are
currently transparent: they read any input, and return the same set
of channels back (unmodified, except for amp).
User visible changes:
* LV2 Instrument support (tracks with both MIDI and audio channels)
* MIDI in/out plugin support
* Generic plugin replication (for MIDI plugins, MIDI/audio plugins)
* Movable meter point
Known Bugs:
* Things seem to get weird on loaded sessions
* Output delivery is sketchy
* 2.0 session loading was probably already broken...
but it's definitely broken now :)
Please test this and file bugs if you have any time...

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).
