This adds support for CIRCUITPY_WIFI_SSID and CIRCUITPY_WIFI_PASSWORD
in `/.env`. When both are defined, CircuitPython will attempt to
connect to the network even when user code isn't running. If the
user code attempts to a network with the same SSID, it will return
immediately. Connecting to another SSID will disconnect from the
auto-connected network. If the user code initiates the connection,
then it will be shutdown after user code exits. (Should match <8
behavior.)
This PR also reworks the default displayio terminal. It now supports
a title bar TileGrid in addition to the (newly renamed) scroll area.
The default title bar is the top row of the display and is positioned
to the right of the Blinka logo when it is enabled. The scroll area
is now below the Blinka logo.
The Wi-Fi auto-connect code now uses the title bar to show its
state including the IP address when connected. It does this through
the "standard" OSC control sequence `ESC ] 0 ; <s> ESC \` where <s>
is the title bar string. This is commonly supported by terminals
so it should work over USB and UART as well.

Everything should be using the keypad module instead.
Note: there are several boards that still had gamepadshift enabled. I
did not contact their authors to make sure they already switched to
keypad in their code and documentation. We should probably wait with
merging this for their go ahead.
os.getenv() will use it (when available) to load variables from
/.env
This will also be useful when we need secrets or config for
CircuitPython outside of the VM (like WiFi credentials.)

The old formulation
* wouldn't work if there were ID3 tags at the end
* would choose whether to background-refill the inbuf
based on a check before skipping to the next sync word, which
could be incorrect.
I think it was aspect "B" that ended up triggering the erroneous EOF
problem fixed in the prior commit. This would depend on specific data
sizes and offsets occuring in the file such that a read would be
scheduled but then the buffer would be filled and left 100% full by
find_sync_word(). It's just lucky(?) that a particular person produced
such a file, and/or many files produced by Audacity have those
characteristics.
This saves 444 bytes on the pygamer build (both commits taken together)
testing performed:
* pygamer (samd51) with ShiftRegisterKeys
* macropad (rp2040) with Keys
* UM feather s2 (esp32-s2) with KeyMatrix
Result:
* all ports still worked nicely
* keys held down at start always registered (>2 trials all boards, >100 trials esp32-s2)
* keys held down are immediately registered after reset() (>100 trials esp32-s2)
* double .reset() is OK, accessing .events throws (only tested esp32-s2)
Some audio implementations, notably samd, really don't like it when
you return 0 samples of data. This was the case when reaching the
end of an MP3 file.
Now, we read forward in an MP3 file to the next sync word during
"get_buffer", so that we can accurately return GET_BUFFER_DONE when the
NEXT call WOULD HAVE resulted in 0 samples.
Tested with @gamblor21's "laugh.mp3" file on a Trellis M4 Express.
This unifies the delay into the post-run delay that also waits
for user input and fake sleep. This ensures we always delay.
Previous code would only delay if the code.py was running when
autoreload was triggered. Now it will always delay.
We also now suspend autoreload when a USB write starts and then
resume on completion. This should prevent reloading in between
sectors of a single write.
This allows you to list and explore connected USB devices. It
only stubs out the methods to communicate to endpoints. That will
come in a follow up once TinyUSB has it. (It's in progress.)

Initially enabled for samd51, this enables reading raw flux data as well
as DOS/MFM formatted media.
This is only the low-level code for reading & decoding flux pulses from a floppy drive.
high level details will live in a Python library.
adafruit-circuitpython-floppy will take care of details like stepping
from track to track, etc.
In testing, I saw that the decoded_samples value kept increasing when I
stopped and restarted playback, as I'd missed setting it back to zero
during the reset operation.
In my testing, there is no way to accurately know how far into a MP3 file
you're currently playing. You can use monotonic time, but that can have
drift versus the audio playback system, which may not be running at exactly
the expected sample rate.
To allow syncing animation with timestamps in a MP3 file, this presents a
new property, decoded_samples, that records the number of audio samples
sent out of the decoder. While this may not be a completely accurate time,
due to mixer delays, it's much better position that the monotonic clock
difference.
Implementation is keeping track of this value in the mp3file structure and
adding to it whenever data is sent out of the decoder. The property
implementation was a copy/paste from current properties in the audiomp3
files.
new utility function for all vectorio shape specializations for testing
whether a screen-space x,y point falls within a shape's x,y.
This respects the current orientation of the screen in the manner of
displayio and vectorio - so your x,y requests are in the same coordinate
domain as your x,y locations and your width/height etc. properties that
ou set on other shapes. I.e., if you're using this for touch points then
you will need to make sure the touch events are in the same x,y domain as
your display.

This helps provide low overhead introspection of shape coverage on screen.
It's envisioned that this will be used for things like touch-and-drag
widget controls, touch "areas" and may help with random ornament placement
on toy Christmas trees.
.. which is what the addition of cmd25 made happen. We still signal
an error when failing to reach the idle state at any other time,
which _is_ different than adafruit_sdcard but I think that it is
correct.
This fixed#5600 according to Dan's testing on a GCM4 on the internal
SD card slot. There are still some ambiguous results on the MM4 with
external SD card slot on 6" jumper wires.
this happens to make the occasional FS dither artifact disappear.
I guess `a * b >> 8` and `(a * b) / 256` are not identical. I'm not
sure if it was just the parens or not, but write the clearer code and
rely on the compiler to substitute an appropriate shift if possible.
This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.
There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
and unnecessary for the vast majority of builds.
Fixes#4314
