When mDNS is active on a netif it registers a lot of timeouts, namely:
mdns_probe_and_announce
mdns_handle_tc_question
mdns_multicast_probe_timeout_reset_ipv4
mdns_multicast_timeout_25ttl_reset_ipv4
mdns_multicast_timeout_reset_ipv4
mdns_send_multicast_msg_delayed_ipv4
mdns_send_unicast_msg_delayed_ipv4
mdns_multicast_probe_timeout_reset_ipv6
mdns_multicast_timeout_25ttl_reset_ipv6
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.
Fixes issue #17621.

Test 'l' and 'll' sized objects. When the platform's `mp_int_t` is not 64
bits, dummy values are printed instead so the test result can match across
all platforms.
Ensure hex test values have a letter so 'x' vs 'X' is tested.
And test 'p' and 'P' pointer printing.

This adds support for %llx (needed by XINT_FMT for printing cell objects)
and incidentally support for capitalized output of %P.
It also reduces code size due to the common handling of all integers.

This commit adds a fast-path optimisation for when a BUILD_SLICE is
immediately followed by a LOAD/STORE_SUBSCR for a native type, to avoid
needing to allocate the slice on the heap.
In some cases (e.g. `a[1:3] = x`) this can result in no allocations at all.
We can't do this for instance types because the get/set/delattr
implementation may keep a reference to the slice.
Adds more tests to the basic slice tests to ensure that a stack-allocated
slice never makes it to Python, and also a heapalloc test that verifies
(when using bytecode) that assigning to a slice is no-alloc.

The test `micropython/ringio_async.py` is a test that requires async

There have been recent build failures in build_renesas_ra_board. It
appears to be the case that a security update for this package was recently
issued by Ubuntu for CVE-2025-4565 and the buggy version is no longer on
package servers. However, it is still referred to by the cached apt
metadata in the GitHub runners.
Add `apt-get update` to fix this, and audit for other sites in `ci.sh`
where it might also be necessary.

This is code makes sure that time functions work properly on a
reasonable date range, on all platforms, regardless of the epoch.
The suggested minimum range is 1970 to 2099.
In order to reduce code footprint, code to support far away dates
is only enabled specified by the port.
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
all timestamps.
On ARM4F, adding support for dates up to year 3000 adds
460 bytes of code. Supporting dates back to 1600 adds
another 44 bytes of code.

This commit adds preliminary support for ST's new STM32N6xx MCUs.
Supported features of this MCU so far are:
- basic clock tree initialisation, running at 800MHz
- fully working USB
- XSPI in memory-mapped mode
- machine.Pin
- machine.UART
- RTC and deepsleep support
- SD card
- filesystem
- ROMFS
- WiFi and BLE via cyw43-driver (SDIO backend)
Note that the N6 does not have internal flash, and has some tricky boot
sequence, so using a custom bootloader (mboot) is almost a necessity.

On STM32H5/STM32H7, SPI flash cannot use as storage device with DMA. SPI

This is due to lower priority of SPI interruption than DMA.

On stm32, the hardware generates an RXIDLE IRQ after enabling the UART,
because the RX line is technically idle.
Signed-off-by: Damien George <damien@micropython.org>
These MCUs only clear the RX idle IRQ if the data register is read, which
won't occur if the only IRQ is the RX idle IRQ (because then reading and
discarding the DR may lead to lost data).
To work around this, explicitly suppress the RX idle IRQ so that it's only
passed through to the Python callback once.
