Remove Canvas::Layout, use Canvas::Container for the same purpose, move child-rendering into Item::render_children() so that it
could theoretically be used by any derived type.
Delivery of fake motion events to the editor needed the event coordinates to be
in canvas space, as they are with "real" events. Editor and other objects had
many redundant groups from timbyr's work on gnomecanvas to scroll by moving
groups. We don't need this anymore with cairo-canvas (though possibly a
stationay background group for the canvas might be useful again one day as in
the SAE logo. Its implementation would be fairly different though, since we
would have to explicitly move the group on every scroll, since nothing else
ever moves on scroll).
Also tweaks to text item placement, and switch TimeAxisViewItem from
name_pixbuf to name_text, since ArdourCanvas::Text is already "pixbuf optimized".

mammoth changes in basic signal flow, total redesign of MIDI channel filtering and more.

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.

... I think. Not sure precisely, conditions were fuzzy, I just tortured my
mouse button until I could reproduce it.

This fixes the note name displayed at a given time to be based on the correct program at that time, and not one in the future.

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().

We really need some kind of more sophisticated assert macro that can be
switched to non-fatal logging mode for release builds. A log message, which is
often all that would happen, is a lot better than a trainwrecked performance...
