This allows the compiler to merge strings: e.g. "update",
"difference_update" and "symmetric_difference_update" will all point to the
same memory.
No functional change.
The size reduction depends on the number of qstrs in the build. The change
this commit brings is:
bare-arm: -4 -0.007%
minimal x86: +150 +0.092% [incl +48(data)]
unix x64: -608 -0.118%
unix nanbox: -572 -0.126% [incl +32(data)]
stm32: -1392 -0.352% PYBV10
cc3200: -448 -0.244%
esp8266: -1208 -0.173% GENERIC
esp32: -1028 -0.068% GENERIC[incl -1020(data)]
nrf: -440 -0.252% pca10040
rp2: -1072 -0.217% PICO
samd: -368 -0.264% ADAFRUIT_ITSYBITSY_M4_EXPRESS
Performance is also improved (on bare metal at least) for the
core_import_mpy_multi.py, core_import_mpy_single.py and core_qstr.py
performance benchmarks.

A script will print "SKIP" if it wants to be skipped, so the test runner
must also use uppercase SKIP.

The UART hardware flow control was not working correctly, the receive FIFO
was always fetched and RTS was never deasserted. This is not a problem
when hardware flow control is not used: normally, if the receive FIFO is
full, the UART receiver won't receive data into the FIFO anymore, but the
current implementation fetches from the FIFO and discards it instead.
The problem is that data is discarded even when RTS is enabled.
This commit fixes the issue by only taking from the FIFO if there is room
in the ring buffer to put the character.

When a task waits on a ThreadSafeFlag (and the wait method returns), the
flag is immediately reset. This was not clear in the documentation, which
appeared to copy the description of the wait method from the Event class.

The current test depends on a specific number and order of packets to pass,
which can't be reproduced every run due to the unreliable UDP protocol.
This patch adds simple packets sequencing, retransmits with timeouts, and a
packet loss threshold, to make the test more tolerant to UDP protocol
packet drops and reordering.
Prior to this fix, if the ADC atten value was not explicitly given then
adc1_config_channel_atten() would never be called.
Fixes issue #8275.

Changes are:
- decision to remount local filesystem on remote device is made only if
"MPY: soft reboot" is seen in the output after sending a ctrl-D
- a nice message is printed to the user when the remount occurs
- soft reset during raw REPL is now handled correctly
Fixes issue #7731.

A backslash in the directory name will end up being passed through to the
device and becoming a backslash in a filename, rather than being
interpreted as directories. This makes "cp -r" problematic on Windows.
Changing to simply "/",join() fixes this.
The correct day-of-week is stored in the RTC (0=Monday, 6=Sunday) so there
is no need to adjust it for the return value of time.localtime().
Fixes issue #7889.

The default stm32lib remains lib/stm32lib, but it can now be easily
overriden at build time by specifying STM32LIB_DIR, or STM32LIB_CMSIS_DIR
and STM32LIB_HAL_DIR.

This also fixes a possible race condition when exiting initialisation mode:
reading then writing to ISR (via ISR &= ~RTC_ISR_INIT) will clear any flags
that were set by the hardware between the read and the write. The correct
way to clear just the INIT bit is to just do a single write via ISR =
~RTC_ISR_INIT, which will not clear any other flags (they must be written
to 0 to clear), and that is exactly what LL_RTC_DisableInitMode does.

And don't assert on the sector number in sector_erase, so it can support
erasing arbitrary sectors.
