initial working version after changes to MIDI channel filtering. may affect metering input too. testing not yet finished
this commit merges many deep changes in ardour's internal architecture,
combined with a total redesign of how MIDI channel filtering works.
data in a track used to flow from JACK port buffers to diskstream's ringbuffers
and was then copied from the ringbuffers into a BufferSet for use during
Route::process_output_buffers(). The butler thread would handle the movement of
data between the ringbuffers and disk.
with this commit, data now flows from JACK port buffers into the BufferSet used
for Route processing, and is copied from the BufferSet into the diskstream's
ringbuffers (the butler thread continues to handle interactions with disk as
usual).
this change allowed a dramatic consolidation of code and simplification of most
aspects of Track/Route::roll() and Track/Route::no_roll(). in particular, see
Route::fill_buffers_with_input() which now concisely describes how we move data
from JACK port buffers into the BufferSet for all Route types (including Tracks).
this work was initially motivated by changing MIDI channel filtering so that we
can process capture and playback independently. there is now a very clean
pathway for this - see MidiTrack::roll() (NOTE: This needs implementing in the
no-roll case too - a TODO item).
the channel selector for MIDI tracks has been moved out of the track header and
is now accessible via the context menu. more work is likely here, to make it
(more) obvious to the user when filtering is going on.
Completely eliminate static MIDI controller name code.
Reduce dependency on midnam_patch.h (which would have saved me several hours if I did it earlier).
Store controller name numbers as an integer.
Keep controller names in a map keyed by int instead of a list for fast lookup.
More cleanup of MIDI::Name code.

Do this via a simple MasterDeviceNames::note_name() function. The same really
needs to be done for program names, this stuff is absolutely brutal to use.
Store note names in a vector indexed by number instead of a list with string
"numbers" for reasonable lookup time.
Make some references const that should be.

Give up trying to hide mode selector when it's useless.
Fix display of program names for default mode.
Abstract out (non-crashy) MidiTimeAxisView::get_device_names().

Accordingly, make "generic" MIDI truly generic, just numbered controllers.
Break up MIDI name UI stuff into manageable functions of reasonable size.
Add convenient method to MIDINameDocument for getting the names for a device.
Tolerate comments in MIDINameDocument ControlNameList.
Can't remove the MIDI name code just yet, since it's still erroneously used by
Automatable::describe_parameter(). This is the cause of a bug where the name
on the automation lane does not match that in the menu.
The plan is to make a very simple pure abstract interface for getting MIDI
names, and make it possible to set one for Automatable (or perhaps pass it to
describe_parameter()). Thus we'll be on the way to supporting names from
sources other than midnam files, namely plugins.
