Currently, `UART.sendbreak()` on esp32 will reconfigure the UART to a
slower baudrate and send out a null byte, to synthesise a break condition.
That's not great because it changes the baudrate of the RX path as well,
which could miss incoming bytes while sending the break.
This commit changes the sendbreak implementation to just reconfigure the TX
pin as GPIO in output mode, and hold the pin low for the required duration.

When detecting the target platform, also check if it has threading and
whether the GIL is enabled or not (using the new attribute
`sys.implementation._thread`). If threading is available, add the thread
tests to the set of tests to run (unless the set of tests is explicitly
given).
With this change, the unix port no longer needs to explicitly run the set
of thread tests, so that line has been removed from the Makefile.
This change will make sure thread tests are run with other testing
combinations. In particular, thread tests are now run:
- on the unix port with the native emitter
- on macOS builds
- on unix qemu, the architectures MIPS, ARM and RISCV-64

This commit fixes building the "btree" example natmod on RV32 when
Picolibc is being used and uses thread-local storage for storing the
errno variable.
The fix is surprisingly simple: Picolibc allows overriding the function
that will provide a pointer to the "errno" variable, and the btree
natmod integration code already has all of this machinery set up as part
of its library integration. Redirecting Picolibc to the already
existing pointer provider function via a compile-time definition is
enough to let the module compile and pass QEMU tests.
This workaround will work on any Picolibc versions (Arm, RV32, Xtensa,
etc.) even if TLS support was not enabled to begin with, and will
effectively do nothing if the toolchain used will rely on Newlib to
provide standard C library functions.
Given that the btree module now builds and passes the relevant natmod
tests, said module is now part of the QEMU port's natmod testing
procedure, and CI now will build the btree module for RV32 as part to
its checks.

When mDNS is active on a netif it registers a lot of timeouts, namely:

mdns_multicast_timeout_25ttl_reset_ipv4

mdns_multicast_timeout_reset_ipv6
mdns_send_multicast_msg_delayed_ipv6
mdns_send_unicast_msg_delayed_ipv6
These may still be active after a netif is removed, and if they are called
they will find that the mDNS state pointer in the netif is NULL and they
will crash.
These functions could be explicitly removed using `sys_untimeout()`, but
`mdns_handle_tc_question()` is static so it's not possible to access it.
Instead use the new `sys_untimeout_all_with_arg()` helper to deregister all
timeout callbacks when a netif is removed.

In order to reduce code footprint, code to support far away dates

New types are defined to identify timestamps.
The implementation with the smallest code footprint is when
support timerange is limited to 1970-2099 and Epoch is 1970.
This makes it possible to use 32 bit unsigned integers for

- Enable I2C and SPI, and add I2C1.
- Enable a filesystem, which matches exactly the rp2 port's RPI_PICO

Support for importing .mpy files is quite fundamental to MicroPython these
days, eg it allows installing more efficient .mpy code via "mip install"
(and installing `unittest` only works with the .mpy version because the .py
version uses f-strings, which are not enabled on the zephyr port). So
enable it generally for use by all boards.
As part of this, also enable:
- min/max: needed by `micropython/import_mpy_invalid.py`, and widely used
- sys.modules: needed by `run-tests.py` to run .mpy tests with --via-mpy
- io module: needed to run .mpy tests, and useful for `io.IOBase`

There are two changes here:
1. Increase the UART input bufffer to 512 bytes. That's necessary to get
basic REPL reliability tests working, and helps improve `mpremote`
usage, eg copying large files.
2. Remove `uart_sem` semaphore. This is no longer needed because
`zephyr_getchar()` should be fully non-blocking and have as low a
latency as possible. `mp_hal_stdin_rx_chr()` (which calls
`zephyr_getchar`) already uses `MICROPY_EVENT_POLL_HOOK` to get
an efficient wait, and doing an extra wait and check for the
semaphore in `zephyr_getchar()` just introduces unnecessary latency and
can lead to slower input, and potentially overflowing the UART input
buffer.

Assuming a 133MHz capable flash in 91cff8e4f1
caused `rp2_flash_set_timing_internal` to set out of range dividers for
some boards (anything with value of 4 and flash that doesn't tolerate
higher speeds).
This affected (at least) the XIAO RP2350 board, making it non-bootable.
Since Pico SDK's `PICO_FLASH_SPI_CLKDIV` is entirely unreliable on a system
with a variable system clock (users can change it at runtime) then use it
only to work out a default `MICROPY_HW_FLASH_MAX_FREQ`.
This value can be overridden in board config.
Note that RP2350's default clock is 150MHz, RP2040's is 125MHz and it has
been certified at 200MHz so it's quite possible that
`PICO_FLASH_SPI_CLKDIV` is unreliable even at standard RP2 clocks.
(If flash timings are marginal then this can manifest as instability rather
than outright failure.)

Signed-off-by: Damien George <damien@micropython.org>
Currently in the esp32 port the size of the SPI flash must be configured at
build time, eg 4MiB, 8MiB, etc. Also, the esp32 partition table must be
configured at build time, which depends on the size of the SPI flash. A
bigger flash means more can be allocated to the user filesystem.
This commit makes it so the SPI flash size is automatically determined at
runtime, and the filesystem size is automatically set to take up as much
room as possible (a "vfs" partition is created automatically if it doesn't
exist).
This works by:
- Setting the SPI flash size to be 4MiB in the build (or some other value,
as long as the firmware app fits).
- Removing the vfs partition from the esp32 partition table (only nvs,
phy_init and firmware, and maybe romfs, remain in the partition table).
- At boot, query the physical size of the SPI flash and use that as the
actual size in the code.
- If it doesn't already exist, automatically create a "vfs" partition which
takes up the flash from the end of all existing partitions to the end of
flash.
This allows simplifying a lot of board configurations, and removing some
board variants that just change the flash size (to be done in a following
commit).
It's also fully backwards compatible, in the following sense:
- Existing boards with MicroPython firmware will continue to work with the
same filesystem, ie the filesystem won't be erased when the firmware is
updated.
- If a user has a custom esp32 partition table and installs MicroPython as
a bare app into the app partition, the new MicroPython firmware will
honour the esp32 partition table and use either "vfs" or "ffat"
partitions as the filesystem.

This commit fixes CI test runs for the `nanbox` target, which were
broken by the unconditional native emitter code output changes in the

The `nanbox` configuration does not enable native emitters of any kind,
and with a full test run that includes executing emitted native code
things would break when doing CI runs.
This is worked around by introducing a common subset of tests that do
not involve the native emitter, and a more comprehensive set of tests
that include both non-emitter and emitter tests. The `nanbox` CI test
run will stop at the first subset, whilst other configurations will run
that and execute further tests.
Function names have been kept the same for steps that involve native
code, with the `nanbox` subset having another one. This should not
trigger any breakage in existing CI configurations or external scripts.

esp_intr_free is not safe to call from the timer ISR because it requires
the current task (the one the ISR interrupted) to be pinned to the same
core as the interrupt was allocated on. Merely disabling the ISR however is
safe since that only requires that we're currently running on the same core
(which the ISR always is), regardless of the current task.
This was causing deadlocks in machine_uart when the ISR happened to
interrupt a task that was not pinned to a specific core.

This commit adds an optional configuration option for the ESP8266 port
that, if the board rebooted due to a crash, will print to stdout some

It is not possible using regular SDK functions to intercept errors and

board is to reboot itself. This is the next best thing, print some
error information just once at boot time after the crash - the least
invasive option given the situation we're in.
