Jeff Epler 91a1706160 MP3: look harder for frame info
Apparently sometimes, a proper "frame info" block is not found after
a "sync word".  Keep looking for one as needed, instead of giving up
after one try.

This was one reason that the "bartlebeats" mp3s would not play.

Jeff Epler a854a76819 audiocore: The arguments to reset_buffer went missing
In conversion I missed these arguments were being passed, but noticed
it when an implausible value for audio_channel was sent to mp3's
reset_buffer method.

It's not clear whether there was any negative impact to this, but it
should be fixed!

Jeff Epler 1cdac3f16a MP3File: Fix stereo playback on samd AudioOut
There were several problems with the way this worked -- the read_count
approach was too complicated and I made a mistake "simplifying" it from
WaveFile.  And when the right channel was returned, it was off by 1 byte,
making it into static.

Instead, directly track which is the "other" channel that has data
available, and by using the right data type make the "+ channel"
arithmetic give the right result.

This requires a double cast (int16_t*)(void*) due to an alignment warning;
the alignment is now ensured manually, but the compiler doesn't make the
necessary inference that the low address bit must be clear.

Jeff Epler 8c841af946 MP3File: Avoid crash in get_buffer when deinitted
When a playing mp3 is deinitted, it's possible to reach get_buffer,
but all the internal pointers are NULL.  This would lead to a hard fault.
Avoid it by returning GET_BUFFER_ERROR instead.

Fix ePaper so it works after a GC.
We weren't correctly collecting the start and stop sequences. As
a result, the GC would free the space and allocate other info
there.

Jeff Epler 7f744a2369 Supervisor: move most of systick to the supervisor
This code is shared by most parts, except where not all the #ifdefs
inside the tick function were present in all ports.  This mostly would
have broken gamepad tick support on non-samd ports.

The "ms32" and "ms64" variants of the tick functions are introduced
because there is no 64-bit atomic read.  Disabling interrupts avoids
a low probability bug where milliseconds could be off by ~49.5 days
once every ~49.5 days (2^32 ms).

Avoiding disabling interrupts when only the low 32 bits are needed is a minor
optimization.

Testing performed: on metro m4 express, USB still works and
time.monotonic_ns() still counts up

Refine _bleio
This PR refines the _bleio API. It was originally motivated by
the addition of a new CircuitPython service that enables reading
and modifying files on the device. Moving the BLE lifecycle outside
of the VM motivated a number of changes to remove heap allocations
in some APIs.

It also motivated unifying connection initiation to the Adapter class
rather than the Central and Peripheral classes which have been removed.
Adapter now handles the GAP portion of BLE including advertising, which
has moved but is largely unchanged, and scanning, which has been enhanced
to return an iterator of filtered results.

Once a connection is created (either by us (aka Central) or a remote
device (aka Peripheral)) it is represented by a new Connection class.
This class knows the current connection state and can discover and
instantiate remote Services along with their Characteristics and
Descriptors.

Add partial display update support.
Different operations to the display tree have different costs. Be
aware of these costs when optimizing your code.
* Changing tiles indices in a TileGrid will update an area
covering them all.
* Changing a palette will refresh every object that references it.
* Moving a TileGrid will update both where it was and where it moved to.
* Adding something to a Group will refresh each individual area it
covers.
* Removing things from a Group will refresh one area that covers all
previous locations. (Not separate areas like add.)
* Setting a new top level Group will refresh the entire display.

Only TileGrid moves are optimized for overlap. All other overlaps
cause sending of duplicate pixels.

This also adds flip_x, flip_y and transpose_xy to TileGrid. They
change the direction of the pixels but not the location.

Fixes #1169. Fixes #1705. Fixes #1923.

Rework the pixel computation to use areas
This changes the displayio pixel computation from per-pixel to
per-area. This is precursor work to updating portions of the screen
(#1169). It should provide mild speedups because bounds checks are
done once per area rather than once per pixel. Filling by area also
allows TileGrid to maintain a row-associative fill pattern even when
the display's refresh is orthogonal to it.
