cc0249c936 nrf/modules/machine/uart: Implement uart.flush() and uart.txdone().
Since uart.write() of the nrf port waits until all bytes but the last
one have been sent, uart.flush() and uart.txdone() are implemented
as empty functions to provide API consistency.

uart.flush()

flush() will always return immediately, even if the last byte
may still be sent.

ret = uart.txdone()

uart.txdone() will always return True, even if the last byte
may still be sent.

8804993d0f esp8266/machine_uart: Implement uart.flush() and uart.txdone().
uart.flush()

flush() will wait until all characters but the last one have been sent.
It returns while the last character is sent. If needed, the calling
code has to add one character wait time. To avoid a permanent lock,
a timeout applies depending on the size of the FIFO and the baud rate.

ret = uart.txdone()

ret is True if no transfer is in progress. It returns already True when
the last byte of a transfer is sent.
ret is False otherwise.

53ebbf10e5 docs/library/machine.I2C: Add a note about I2C pull-up resistors.
Quite regularly users complain about unexpected behavior of I2C, calling it
a bug, when in fact the trouble is caused by missing pull-up resistors.  So
this commit adds a note to the documentation, in the slim hope that people
will find and read it.

9a826e0f24 lib/lwip: Update lwIP to v2.1.3, tag STABLE-2_1_3_RELEASE.
There don't seem to be many changes going from v2.1.2 to v2.1.3 of lwIP.
Mostly they are:
- IPv6 fixes and improvements
- changes to apps and other code that MicroPython doesn't use
- comments and tests
- minor bug fixes

In particular there doesn't look to be any change to the API of any
function used by MicroPython.

Network multi tests pass on PYBD_SF2 and PYBD_SF6.  PYBD_SF2, PYBD_SF6 and
PICO_W have unchanged iperf3 performance.  Similar results for networking
on the mimxrt port.

88864587f5 py/objstr: Always ensure mp_obj_str_from_vstr is unicode-safe.
Now that we have `mp_obj_new_str_type_from_vstr` (private helper used by
objstr.c) split from the public API (`mp_obj_new_str_from_vstr`), we can
enforce a unicode check at the public API without incurring a performance
cost on the various objstr.c methods (which are already working on known
unicode-safe strings).

8a0ee5a5c0 py/objstr: Split mp_obj_str_from_vstr into bytes/str versions.
Previously the desired output type was specified.  Now make the type part
of the function name.  Because this function is used in a few places this
saves code size due to smaller call-site.

This makes `mp_obj_new_str_type_from_vstr` a private function of objstr.c
(which is almost the only place where the output type isn't a compile-time
constant).

This saves ~140 bytes on PYBV11.

986ad6bf1d stm32/boardctrl: Use HAL_Delay instead of mp_hal_delay_ms.
Not safe to use mp_hal_delay_ms before boot if threading is enabled,
because threading will not have been initialised, and
MICROPY_EVENT_POLL_HOOK assumes threading is initialised.

HAL_Delay doesn't call MICROPY_EVENT_POLL_HOOK, but is still
power-efficient like mp_hal_delay_ms (unlike mp_hal_delay_us).

Fixes #7816.

It used to be 10 bit times, which is too short.  The break state must be
longer than a regular character time, at least 13 bit times.  This is now
implemented by reducing the baudrate while sending the "0".  The break time
will now vary with data length and parity setting, but will at least be 15
bit times.

Tested with a GENERIC_SPIRAM, GENERIC_C3 and UM_TINYS2 board.

very minimal mp_builtin___import__, ports can still allow limited forms
