b168784fa0 aesio: add basic AES encryption and decryption 
This adds initial support for an AES module named aesio.  This
implementation supports only a subset of AES modes, namely
ECB, CBC, and CTR modes.

Example usage:

```
>>> import aesio
>>>
>>> key = b'Sixteen byte key'
>>> cipher = aesio.AES(key, aesio.MODE_ECB)
>>> output = bytearray(16)
>>> cipher.encrypt_into(b'Circuit Python!!', output)
>>> output
bytearray(b'E\x14\x85\x18\x9a\x9c\r\x95>\xa7kV\xa2`\x8b\n')
>>>
```

This key is 16-bytes, so it uses AES128.  If your key is 24- or 32-
bytes long, it will switch to AES192 or AES256 respectively.

This has been tested with many of the official NIST test vectors,
such as those used in `pycryptodome` at
39626a5b01/lib/Crypto/SelfTest/Cipher/test_vectors/AES

CTR has not been tested as NIST does not provide test vectors for it.

507e17fbf1 displayio: Fix "bus type" problem introduced at 8cba145c90 
When allocate_display_bus_or_raise was factored out, the assignment
of the bus's Python type was lost.  Restore it.

This would have affected displays of any type other than RGBMatrix, when
they were created dynamically.  Boards with displays configured in flash
were unaffected.

busio/UART: Correct and clarify readline() return. 
Surely readline() "rtype" is string not int as stated (and not bytes as some might expect).

Also it is not totally unambiguous what happens on a timeout so it would help to clarify in docs that on a timeout 
it does NOT return with what it has read so far, rather it leaves all that in the buffer ready for a future read and returns nothing.

Likewise clarify that if timeout=0 but there is no newline it DOES return what it has read so far (NOT None). 

At least this is what I think it does and/or is supposed to do!

Python docs are generally not too explicit about what is the proper treatment, so perhaps all the more reason to
clarify the interpretation adopted?

0ce9c008c5 Protomatter: Make all arguments kw-only, add rgb count and optional height checking 
They're not readily distinguishable by type.

I also added the requested height optional parameter; this is checked
against the computed one.  It's not feasible to use this parameter to
artificailly reduce the number of used rows, because changes in the
underlying C protomatter library would be required.

Finally, I added a better error message when the number of RGB pins was
not what was expected.

02154caf24 MP3File: Add a settable ".file" property 
This enables jeplayer to allocate just one MP3File at startup, rather
than have to make repeated large allocations while the application is
running.

The buffers have to be allocated their theoretical maximum, but that
doesn't matter much as all the real-life MP3 files I checked needed
that much allocation anyway.

feb8eb935b audiosample: convert to use a protocol

238e121236 protocols: Allow them to be (optionally) type-safe 
Protocols are nice, but there is no way for C code to verify whether
a type's "protocol" structure actually implements some particular
protocol.  As a result, you can pass an object that implements the
"vfs" protocol to one that expects the "stream" protocol, and the
opposite of awesomeness ensues.

This patch adds an OPTIONAL (but enabled by default) protocol identifier
as the first member of any protocol structure.  This identifier is
simply a unique QSTR chosen by the protocol designer and used by each
protocol implementer.  When checking for protocol support, instead of
just checking whether the object's type has a non-NULL protocol field,
use `mp_proto_get` which implements the protocol check when possible.

The existing protocols are now named:
    protocol_framebuf
    protocol_i2c
    protocol_pin
    protocol_stream
    protocol_spi
    protocol_vfs
(most of these are unused in CP and are just inherited from MP; vfs and
stream are definitely used though)

I did not find any crashing examples, but here's one to give a flavor of what
is improved, using `micropython_coverage`.  Before the change,
the vfs "ioctl" protocol is invoked, and the result is not intelligible
as json (but it could have resulted in a hard fault, potentially):

    >>> import uos, ujson
    >>> u = uos.VfsPosix('/tmp')
    >>> ujson.load(u)
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ValueError: syntax error in JSON

After the change, the vfs object is correctly detected as not supporting
the stream protocol:
    >>> ujson.load(p)
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    OSError: stream operation not supported

e188ae8b23 time: struct_time: allow construction like a namedtuple, too 
Whenever there is more than one argument, delegate the operation to
namedtuple_make_new.  This allows other circuitpython-compatible
idioms, like with keywords
    time.struct_time(tm_year=2000, tm_mon=1, tm_mday=1, tm_hour=0,
        tm_min=0, tm_sec=14, tm_wday=5, tm_yday=5, tm_isdst=-1)
with 9 positional arguments, etc.

The only vaguely plausible CPython behavior still not permitted in
CircuitPython that I found is constructing a timetuple from a length-9
list, a la
    time.struct_time(list(time.localtime())

Even better, by getting rid of an error message, the build shrinks a
tiny bit.

5115fdaa6f shared-bindings: I2SOut: Ensure object is deinitialised 
(or deinitialized, for those of us on this side of the pond)

Otherwise, a sequence like
```
audio = audiobusio.I2SOut(bit_clock=board.D6, word_select=board.D9, data=board.D10)
sine_wave_sample = audiocore.RawSample(sine_wave)
audio.play(sine_wave_sample, loop=True)
del audio
```
could free the memory associated with audio without stopping the
related background task.  Later, when fresh objects are allocated within
a now-freed memory region, they can get overwritten in the background
task, leading to a hard crash.

This presumably can affect multiple I2S implementations, but it was
reported against the nRF one.

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.
