We need a MidiStateTracker to determine notes whose end is not reached
during the call to ::write_one_track(), so that we can resolve them
in the output (SMF) source. This required some changes to the ::export_stuff()
API for tracks.
In addition, we now take the source "lock" just once during ::write_one_track()
rather than every time we write. This isn't an integral part of the
note tracking, but fell out along the way.
Finally, note that although we use a vector to handle MIDI "sources" here,
it is expected that there is only 1 MIDI source at present. Leave vectors in
place since it is possible that ::write_one_track() could be modified
in the future to change that.

Not all is working right yet, however

This also consolidates code to test if a processor can be frozen
from various places.

In prior versions: if Auto Input was enabled, the default behavior was
to monitor the Input of all tracks when stopped; even if they aren't armed.
Tape Machine Mode changed the behavior of Auto Input so that it doesn't
always monitor the track inputs when transport is stopped.
After some discussion on IRC, we determined that Tape mode is likely
more practical for a DAW user, and therefore a better default.
Rather than default an ambiguously-named preference "on", we decided
to invert the behavior, rename it sensibly(?), and default it OFF.

Global variables that can written by anyone are to be avoided.
This also simplifies exposing SessionPlaylists as Lua bindings.

* Processor implement get_state(), classes derived from Processor
implement protected ::state() -- as documented in processor.h
* likewise for Route, Track: make ::state() a protected interface
* removal of "full_state", use explicit "template_save"
* use RAII/Unwind to skip saving automation-state

- Fix API call to add region(midi_region) -- set count to "1"
- Forward DataRecorded() signal
- remove botched merge/rebase"
a4a87f56 accidentally brought back code from old-destructive API
which was removed in af103cf3 and 08c13007
There is no per track NonLayered record mode anymore, it's session global.
- set can_record correctly to not accidentally clear last capture sources
for cont'd recording (toggle track's rec-arm)

We want Track to shrink, and logic consolidation is always good. Route already knew about
disk_reader and disk_writer, now it knows about _monitoring_control too

THIS WILL NOT RUN. THIS REQUIRES MANY CHANGES

The gain property float <=> string conversion is now performed using
PBD::to_string/string_to via XMLNode

Route::no_roll(), Route::roll(), Track::no_roll(), AudioTrack::roll()
and MidiTrack::roll() all had the exact same loop for flushing buffers
of their Delivery processors. That was a lot of replicated code that had
to be kept synchronised by hand. Put that code into a protected method
Route::flush_processor_buffers_locked() which is called instead.

Pass current (latency compensated) cycle times to plugin.
This fixes time-reporting to plugins and also fixes automation
and when bouncing (the session->transport* is not valid) etc.

remote control ID and "order keys" have been removed.

and used. The controls now own their own state, rather than proxy for state in their owners.
Massive changes all over the code to accomodate this. Many things are not finished. Consider this a backup safety commit

Executive decisions were necessary in a couple of places about the correct group disposition
behaviour, notably faderport and OSC surfaces

bug:
1) freeze a track
2) Session Cleanup > Cleanup unused sources
2a) confirm playlist deletion
3) quit, reload -> track is no longer frozen
because _freeze_record.playlist is missing.
session is in an odd state.

Paul Davis was responsible for introducing almost all of this.

parent Track::set_state() sets the diskstream

fixes Tape tracks on session load

1) Disambiguate 1.0 to GAIN_COEFF_UNITY, and 0.0 to GAIN_COEFF_ZERO
2) Add GAIN_COEFF_SMALL which replaces SMALL_SIGNAL (-140dB)
3) GAIN_COEFF_SMALL can used to avoid interpolating towards -inf on a db scale
4) GAIN_COEFF_SMALL is used to detect very small (denormal?) gains and memset to zero

operation is undefined. C works on all platforms

This probably isn't correct in several ways, but it works more than it did, so
I figure it's push worthy.
Still not working:
* Saving mute automation list
* Dragged control points are not snapped to model restrictions
(boolean, in this case, but general problem)
* Line goes funny if you record mute automation
(as opposed to drawing it which works)

Theoretically one could alter the plugins after a delivery even on a
frozen track. ..or even change settings, the ordering and add/remove
plugins after the frozen part of a track.
We won't go there. Frozen is frozen. this API is not needed after all.
This reverts commit a771dea20332bf31162ccb13a518e0348b441dd1.
