If the CDC receive buffer was full and some code read less than 64 bytes
(wMaxTransferSize), the CDC code would submit an OUT transfer with N<64
bytes length to fill the buffer back up.
However if the host had more than N bytes to send then it would still send
the full 64 bytes (correctly) in the transfer. The remaining (64-N) bytes
would be lost.
Adds the restriction that CDCInterface rxbuf has to be at least 64 bytes.
Fixes issue #885.

When running tests from subfolders, import by "full dotted path" rather
than just module name, removing the need to add the test parent folder to
`sys.path`.
This matches CPython more closely, which places `abspath(top)` at the start
of `sys.path` but doesn't include the test file parent dir at all.
It fixes issues where projects may include a `test_xxx.py` file in their
distribution which would (prior to this change) be unintentionally found by
unittest-discover.

All of the runable package tests are run together in the new `tools/ci.sh`
function called `ci_package_tests_run`. This is added to a new GitHub
workflow to test the packages as part of CI.
Some packages use `unittest` while others use an ad-hoc test script.
Eventually it would be good to unify all the package tests to use
`unittest`.

Since deque was removed from this repository the built-in one needs to be
used, and that doesn't have unbounded growth. So use a list instead, which
is adequate becasue contextlib only needs append and pop, not double ended
behaviour (the previous pure-Python implementation of deque that was used
here anyway used a list as its storage container).
Also tweak the excessive-nesting test so it uses less memory and can run on
the unix port.

Storing references to tasks is required by CPython, and enforced by Ruff
RUF006. In this case it's also reasonable to cancel these tasks once the

This changes almost all uses of "u-module" to just "module" for the
following built-in modules:
- binascii
- collections
- errno
- io
- json
- socket
- struct
- sys
- time
There are some remaining uses of "u-module" naming, for the cases where the
built-in module is extended in Python, eg `python-stdlib/os` uses `uos`.
Also, there are remaining uses of `utime` when non-standard (compared to
CPython) functions are used, like `utime.ticks_ms()`.

This removes all the hard-coded request headers from the requests module so
they can be overridden by user provided headers dict. Furthermore allow
streaming request data without chunk encoding in those cases where content
length is known but it's not desirable to load the whole content into
memory. Also some servers (e.g. nginx) reject HTTP/1.0 requests with the
Transfer-Encoding header set.
The change should be backwards compatible as long as the user hasn't
provided any of the previously hard-coded headers.

This tests both encoding and decoding multiple 16-bit and 32-bit services
within the one advertising field.
Signed-off-by: Damien George <damien@micropython.org>
Fixes are needed to support the cases of:
- There may be more than one UUID per advertising field.
- The UUID advertising field may be empty (no UUIDs).
- Constructing 32-bit `bluetooth.UUID()` entities, which must be done by
passing in a 4-byte bytes object, not an integer.
Signed-off-by: Damien George <damien@micropython.org>
When multiple UUIDs of the same size are advertised, they should all be
listed in a single LTV. Supplement to the Bluetooth Core Specification,
Part A, §1.1.1: "A packet or data block shall not contain more than one
instance for each Service UUID data size."
When aioble construct the advertisement data, it is creating a new data
block for each UUID that contains only that single UUID. Rather than,
e.g., a single 16-bit UUID block with a list of multiple UUIDs.
Not only is this against the specification, it wastes two bytes of limited
advertisement space per UUID beyond the first for the repeated data block
length and type fields.
Fix this by grouping each UUID size together.

The value for the `timeout_ms` optional argument to
`DeviceConnection.disconnected()` async method is changed from 60000 to
None. This way users awaiting a device disconnection using `await
connection.disconnected()` won't be surprised by a 1 minute timeout.
Only read from the temp characteristic if the connection is still active.
Improves the example by avoiding a TypeError exception if/when the sensor
disconnects.
This sets the disconnected timeout to None, so that the peripheral waits
forever for the client to disconnect. Previously the peripheral would
abort the connection after 60 seconds (because that's the default timeout).

Changes are cosmetic - and maybe very minor code size - but not functional.
_reg_read() was calling struct.packinto() with an incorrect number of

If send completes before the first call to poll_send(), the driver could
get stuck in _sync_wait(). This had much less impact before rp2 port went
tickless, as _sync_wait(will_irq=True) calls machine.idle() which may not
wake very frequently on a tickless port.

According to the docs, only freq_khz was needed for working output.
However:
- Without output_power setting, no output from SX1262 antenna (theory:
output routed to the SX1261 antenna).
- SF,BW,etc. settings were different from the SX127x power on defaults, so
modems with an identical configuration were unable to communicate.
