correct length
Without this change, such regions end up with insanely large (though legal) lengths

Not all is working right yet, however

The stereo-width panner is not generally useful. In order to
change the azimuth, width has to be reduced, which usually leads
to comb-filter artifacts.
Equal power stereo, also matches the default mono to stereo panner
better than the stereo-width panner.
Last but not least, control surfaces only have an azimuth control
knob, without an easy way to reduce width, this leaves
the panner insensitive.

Direct call to Session::cleanup_sources() from ARDOUR_UI::cleanup()
didn't zero initialize size. This centralizes initialization,
so cleanup_trash_sources() does not need to explicitly clear it.

Previously when loading Ardour v2, v3-5 sessions, tracks were
created with a dummy name "toBeResetFroXML".
In v6, Track::init() creates a playlist when the track name is
not empty. Later Track::set_state() calls set_name(). When a
playlist exists, the playlist's name is set to match the track's name.
When loading v6 sessions none of this happens. A previously loaded
playlist will be assigned by ID.
Older versions identified Playlists by name and by the time the
playlist is assigned, there may be ambiguities. With the default
(track-name = playlist-name) two playlists with the same name exist:
(1) the playlist loaded from the session file
(2) the playlist created by Track::init()
Playlists are stored in an ordered std::set<shared_ptr<Playlist>>,
and name-lookup iterates over the set.
When loading an old session after starting Ardour, it is very
likely to always lookup the playlist (1), because new, later
allocations from (2) are on top of the heap and ordered last.
The session seemingly loads correctly, except for lingering,
unused empty playlists "toBeResetFroXML" renamed to "Track name"
that were never deleted.
However when loading an old session from a running instance,
ordering is mostly random, and many tracks end up with using
the empty playlist (2) instead of the correct playlist (1).

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

DiskReader::{inc,dec}_no_disk_output()
|
|
DiskReader::_no_disk_output is set
Under those conditions, the DR will not execute a code path that will cause the declick to take place
and therefore the declick will never finish

in 5.x, we would only run the MTC parsing code if slaved to MTC. That's no longer true in 6.0, and without
this change, MTC will cause a locate at startup

This fixes issues with send-panner bypass whenever the
target bus input-count is different from the send's channel count.
--
Previously, when the aux-send panner was bypassed, data was
copied using BufferSet::read_from().
This sets the channel count of the output buffer set (here: mixbufs)
to match the input (here: bufs).
e.g. mono to stereo, "1 in -> 2 out" out was changed to "1 in -> 1 out".
Un-bypassing the panner later does not reconfigure the I/O.
Mixbufs remained mono, and PannerShell::run() "1 in -> 1 out"
does nothing. The panner was effectively not functional.

is created

loop end
Locating the start of the loop range at transport start does not count as "have looped". This was preventing
pre-roll when starting to loop, which in turn caused data/event loss because the start/end sample ranges
would be incorrect inside process

This reverts commit 8702ff2189665b473918ed60f34b6be4010a06f7,
and b10d9cf09bf6150f0ba0eae5dc34fd8db8b2fa91.
There was a misconception on the iterator (port vs message
in sequence), besides Ardour's mixer-strip is preferably used
with a single MIDI port. Most plugin-standards also only support
one port.
If need be LuaDSP run_map() can be used to handle multiple
MIDI I/O ports already.

We accomplish this by explicitly setting the global_obs to NULL after
free'ing it. The crash that led to this fix can be replicated as such
$ sendosc localhost 3819 /set_surface i 8 i 159 i 8
$ sendosc localhost 3819 /set_surface i 0 i 0 i 0
$ sendosc localhost 3819 /set_surface i 0 i 0 i 0
In this example the observer is created, then free'd, and then free'd
*again* because the new observer was never made (sur->feedback[x]
checks fail)

gcc, and recent clang-10 can construct new objects
using references as arguments.
However clang-8 (and MSVC?) do not:
"error: no matching function for call to 'operator new'"
The compiler apparently does not expand the template
class A <-> `A*` vs. `A const&`
for different cases.

This is mainly for windows compatibility "%F" is not supported.
An alternative would be to s/%F/%Y-%m-%d/ to produce the ISO date.

Mixbus v6 uses AutomationType BusSendLevel like other Sends,
however with different min/max range compared to default Ardour
Aux sends. Control surfaces should use interface/internal API.

Bug was introduced in 128a45954cf, declick-amp gain was
overridden, but declick not cleared. For some reason this did
not affect audio-only exports nor all session exports.

start_post_processing() may be called from the freewheeling

This is a dumb stack allocator using LIFO allocation/free, with
a fallback to new/delete. This works well for small STL containers
in particular std::vector, but it's also suitable for std::map<>,
in particular copy constructing small POD maps (plugin pin mappings).
Eventually this could be combined with TLSF for a flexible
memory arena management. This is however not currently needed
for any the planned use-cases.
This code is ANSI C++98 compatible, and yet also works with
modern C++11, C++14
