If there are any network issues, mqtt will block on the socket
non-deterministically. This commit introduces a `timeout` option which
can be used to set a finite timeout on the socket. Upon any issue, mqtth
lib will throw exception.
This allows the following arguments to be passed to `device.connect()`:
* scan_duration_ms
* min_conn_interval_us
* max_conn_interval_us
These are passed as-is to `gap_connect()`. The default value for all of
these is `None`, which causes gap_connect to use its own defaults.

To use this feature you need to create a usb device signaling remote wakeup
and then enable remote wakeup on the host (on linux write enabled to
/sys/bus/usb/devices/<device>/power/wakeup). Then you can wake up the host
when is on standby using USBDevice.remote_wakeup.

This is to replace a commit which added locking here but caused some other
problems. The idea behind the Buffer class is that a single producer can
call pend_write() more than once and it's idempotent, however this is very
complex to extend across multiple threads.

The USB pending transfer flag was cleared before calling the completion
callback, to allow the callback code to call submit_xfer() again.
Unfortunately this isn't safe in a multi-threaded environment, as another
thread may see the endpoint is available before the callback is done
executing and submit a new transfer.
Rather than adding extra locking, specifically treat the transfer as still
pending if checked from another thread while the callback is executing.

Currently, the LoRa SX126x driver dynamically creates at least one,
sometimes two, memoryview objects with each call to `_cmd`. This commit
simply provides the class with a long-lived memoryview object for `_cmd` to
easily slice as necessary.
Unlike the SX127x chips, Semtech unfortunately designed the SX126x modems
to be more command-centric (as opposed to directly setting registers).
Given the amount `_cmd` is called during normal device operation, even a
minor improvement here should have a decent impact.
Basic TX and RX tests pass on hardware.

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.

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 tests both encoding and decoding multiple 16-bit and 32-bit services
within the one advertising field.

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.

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
arguments but it seems like MicroPython didn't mind, as result is correct
for both versions.

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.
