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.

If big integer support is 'long long' then mp_parse_num_integer() can
parse to it directly instead of failing over from small int. This means
strtoll() is no longer pulled in, and fixes some bugs parsing long long
integers (i.e. can now parse negative values correctly, can now parse
values which aren't NULL terminated).
The (default) smallint parsing compiled code should stay the same here,
macros and a typedef are used to abstract some parts of it out.
When bigint is long long we parse to 'unsigned long long' first (to avoid
the code size hit of pulling in signed 64-bit math routines) and the
convert to signed at the end.
One tricky case this routine correctly overflows on is
int("9223372036854775808") which is one more than LLONG_MAX in decimal. No
unit test case added for this as it's too hard to detect 64-bit long
integer mode.

Long long big integer support now raises an exception on overflow rather
than returning an undefined result.
Also adds an error when shifting by a negative value.

These tests cover the use of mp_obj_new_int_from_str_len when
mp_parse_num_integer overflows the SMALLINT limit, and also the case where
the value may not be null terminated.
Placed in a separate test file so that extmod/json test doesn't rely on
bigint support.

These will run on all ports which support them, but importantly
they'll also run on ports that don't support arbitrary precision
but do support 64-bit long ints.
Includes some test workarounds to account for things which will overflow
once "long long" big integers overflow (added in follow-up commit):
- uctypes_array_load_store test was failing already, now won't parse.
- all the ffi_int tests contain 64-bit unsigned values, that won't parse
as long long.

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.

and incidentally support for capitalized output of %P.

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.
