3faf229853 py/misc: Add a way to detect sanitizer builds.
Clang and gcc>=14 can use __has_feature() to detect if a sanitizer
is enabled, but older GCC has no mechanism - need to set a macro
explicitly for this to be recognised.

Necessary for increasing some resource limits in sanitizer builds.
Important not to use to avoid real issues!

This work was funded through GitHub Sponsors.

d81d56cc4d tools/ci: Add UBSan to longlong CI build.
Also rewrite the sanitizer argument variables to not assume a variant.

longlong variant currently fails in this config, due to a bug fixed
in follow-up commit.

1b35116c92 stm32/dac: Fix 12-bit DAC issue on STM32H5.
For STM32H5, to use 12-bit DAC, the DMA parameter should set:
- Actual DMA source datawidth to CTR1.
- The length is the amount of data to be transferred from source to
  destination in bytes.

Also, this commit modifies the (dummy) definition of DMA_CIRCULAR for
STM32H5 to prevent conflict with data width specification.

The HP and HE CPUs have double-precision hardware floating point, so can
use the armv7emdp architecture.

This allows frozen code to use native/viper/asm_thumb decorators.

e58848a21e alif/machine_rtc: Implement RTC.datetime to get and set the RTC.
The LPRTC peripheral is a 32-bit counter with a 16-bit prescaler.  It's
configured here to count at 1Hz (to get maximum date range) and then the
prescaler value is used to get 30 microsecond resolution.  That's
essentially a 32+15=47-bit counter.

b3cd1a355e extmod/modtime: Move tuple creation to common localtime implementation.
This factors code out of the ports and into the common `time.localtime`
implementation in `extmod/modtime.c`.  That helps to reduce code
duplication, prevent errors in implementation, and reduce code size on
some ports (mimxrt and stm32 at least).

2bba507148 tests: Require SSL certificate file to be available for test to run.
Previously, any test needing an SSL certificate file would automatically
skip if the file could not be found.  But that makes it too easy to
accidentally skip tests.

Instead, change it so that the test fails if the certificate file doesn't
exist.  That matches, for example, the fact that the test fails if
networking (LAN, WiFi) is not active.

0f5f6484a2 tests/run-tests.py: Add support for .native.exp expected output files.
There are currently a few tests that are excluded when using the native
emitter because they test printing of exception tracebacks, which includes
line numbers.  And the native emitter doesn't store line numbers, so gets
these tests wrong.

But we'd still like to run these tests using the native emitter, because
they test useful things even if the line number info is not in the
traceback (eg that threads which crash print out their exception).

This commit adds support for native-specific .exp files, which are of the
form `<test>.py.native.exp`.  If such an .exp file exists then it take
precedence over any normal `<test>.py.exp` file.

(Actually, the implementation here is general enough that it also supports
`<test>.py.bytecode.exp` as well, if bytecode ever needs a specific exp
file.)

This commit simplifies the emitter code in charge of generating opcodes
performing less-than and less-than-or-equal comparisons.

By rewriting the SLT/SLTU opcode generator (handling less-than
comparisons) and de-inlining the less-than comparison generator call in
the less-than-or-equal generator, the output binary is ~80 bytes smaller
(measurements taken from the QEMU port).

This commit provides an implementation for viper boundary tests that can
work even without big int support.

Since it uses a fixed-size buffer to hold values to work with, this
should work on any platform as long as its integers are at least 32 bits
wide, regardless its configuration on how big integers can get.

f10707febb extmod/modlwip: Support family specification in getaddrinfo.
`socket.getaddrinfo()` supports the specification of an address family;
however, the LwIP implementation does not use it. This change allows the
application to specify the address family request in DNS resolution. If
no family is specified, it falls back to the default preference
configured with `network.ipconfig()`.

14ccdeb4d7 extmod/modre: Add support for start- and endpos.
Pattern objects have two additional parameters for the ::search and ::match
methods to define the starting and ending position of the subject within
the string to be searched.

This allows for searching a sub-string without creating a slice.  However,
one caveat of using the start-pos rather than a slice is that the start
anchor (`^`) remains anchored to the beginning of the text.

20e1ae0733 tools/mpremote: Fix encoding error in PyboardCommand.
This is a fix for utf-8 decoding errors that are thrown when non-utf-8
content is received.  For instance during a reboot of an ESP8266 module.

The fix is to handle conversion errors by replacing illegal characters.
Note that these illegal characters most often occur during an MCU reboot
sequence when the MCU is using baudrates different from 115200.

8c47ff7153 esp32/network_ppp: Correctly clean up PPP PCB after close.
If PPP is still connected, freeing the PCB will fail and thus instead we
should trigger a disconnect and wait for the lwIP callback to actually
free the PCB.

When PPP is not connected we should check if the freeing failed, warn
the user if so, and only mark the connection as inactive if not.

When all this happens during garbage collection the best case is that
the PPP connection is already dead, which means the callback will be
called immediately and cleanup will happen correctly. The worst case is
that the connection is still alive, thus we are unable to free the PCB
(lwIP won't let us) and it remains referenced in the netif_list, meaning
a use-after-free happens later when lwIP traverses that linked list.

This change does not fully prevent that, but it *does* improve how the
PPP.active(False) method on the ESP32 port behaves: It no longer
immediately tries to free (and fails), but instead triggers a disconnect
and lets the cleanup happen correctly through the status callback.

adcfdf625b esp32/network_ppp: Use non-thread-safe API inside status callback.
The status callback runs on the lwIP tcpip_thread, and thus must use the
non-thread-safe API because the thread-safe API would cause a deadlock.

361c615f3e esp32/network_ppp: Use thread-safe API for PPPoS input.
A small follow-up to 3b1e22c669, in which
the entire PPP implementation was reworked to more closely resemble the
extmod version. One of the differences between extmod and the ESP32 port
is that the ESP32 port uses the thread-safe API, but in that changeset
the PPP input function was accidentally changed to use the non-safe API.
