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.

The inclusion of `umachine` in the list of built-in modules is now done
centrally in py/objmodule.c. Enabling MICROPY_PY_MACHINE will include this
module.
As part of this, all ports now have `umachine` as the core module name
(previously some had only `machine` as the name).

This change allows the same heap allocation rules to be used when using
malloc regardless if the board has SPRAM or normal RAM.
Integrating with the esp32-camera for example requires that ESP32 SPRAM be
allocatable using the esp-idf capabilities aware allocation functions. In
the case of esp32-camera it's for the framebuffer.
Detect when CONFIG_SPIRAM_USE_MALLOC is in use and use the standard
automatic configuration of leaving 1/2 of the SPRAM available to other
FreeRTOS tasks.
For example the ESP32-C3 has 2 TX channels and 2 RX channels in total, and
in this case channel 1 must be the default for bitstream.

This commit adds support for the STM32G4 series of MCUs, and a board
definition for NUCLEO_G474RE. This board has the REPL on LPUART1 which is
connected to the on-board ST-link USB-UART.
It's needed at least on F4 because this file overrides the weak function
HAL_RCC_DeInit() from hal_rcc.c.

PLL3-Q is more reliable than PLL1-Q for the USB clock source when entering
mboot from various reset states (eg power on vs MCU reset). (It was found
that if the main application used PLL3-Q then sometimes the USB clock
source would stay stuck on PLL3-Q and not switch to PLL1-Q after a reset.)
Other related changes:
- SystemCoreClockUpdate() should be called on H7 because the calculation
can be involved in some cases.
- __set_PRIMASK(0) should be called because on H7 the built-in ST DFU
bootloader exits with IRQs disabled.
