Zephyr allows setting both GPIO_OUTPUT and GPIO_INPUT on a pin, which means
it's an output pin that can have its current value read.
Fixes issue #17596.

Before this commit the UART would only work in very simple use cases.
Receiving large amounts of data would result in lost bytes. Plus the print
function would crash due to `uart_config_get()` returning incorrect values.
Additionally, receiving data with `timeout==0` would fail even if data was
already available in the internal UART Rx FIFO.
This commit fixes those issues. The non-implemented functions have also
been made usable.

The IDF panic handler resets the watchdog timeout to prevent the printing
of the error message from being cut off by a WDT reset. We use the exact
same function call in our wrapper function for the same purpose.
In IDFv5.4.2 the function used for this was changed from
`esp_panic_handler_reconfigure_wdts` to `esp_panic_handler_feed_wdts`,
specifically in this commit:

This removes the need for an explicit `sys_settrace_features.py.exp` file.
This means that people testing locally will also need to install Python
3.11 in some way, such as with pyenv or uv, and use it during
`make VARIANT=coverage test`, or they will get failures.
When using Python from GitHub actions/setup-python, pip3 can't be wrapped
by sudo, because this invokes the operating system python instead.

The argument corresponding to a `%q` specifier must be of type `qstr`, not
a narrower type like `int16_t`. Not ensuring this caused an assertion
error on one Windows x64 build.

This commit introduces an optional feature to provide to native emitters
the fully qualified name of the entity they are compiling.
This is achieved by altering the generic ASM API to provide a third
argument to the entry function, containing the name of the entity being
compiled. Currently only the debug emitter uses this feature, as it is
not really useful for other emitters for the time being; in fact the
macros in question just strip the name away.

Changes in this commit:
- Handle SerialException on Windows when device disconnects.
- Print clean 'device disconnected' message instead of stack trace.
- Fix terminal formatting issues on Linux after disconnect.
- Return disconnected state after console cleanup to avoid terminal issues.
This ensures proper disconnect messages on both platforms without showing
confusing error traces to users.

This commit cleans up the single entry point integer-indexed load/store
emitters that have been built by merging the single operand type
load/store functions in 1f5ba6998b.
To follow the same convention found in RV32 and Xtensa emitters, the
function operand size is not named after the left shift amount to apply
to the initial offset to get its true byte offset, but by a generic
"operand size".
Also, those functions were updated to use the new MP_FIT_UNSIGNED macros
to perform bit width checks when figuring out which opcode encoding is
the best one to use.

This commit introduces a mechanism to customise the code that is
injected to the board when performing a test file upload and execution.
A new argument, --begin", is added so regular Python code can be
inserted in the injected fragment between the module file creation and
the effective file import. This is needed for running larger tests
(usually ones that have been pre-compiled with
"--via-mpy --emit native") on ESP8266, as that board does not have
enough memory to fit certain blocks of code unless additional
configuration is performed.

This commit reworks the Viper pointer boundary tests in order to make
them more accurate and easier to extend.
The tests are now easier to reason about in their output, using easier
to read values, and bit thresholds are now more configurable. If a new
conditional code sequence is introduced, adding a new bit threshold is
just a matter of adding a value into a tuple at the beginning of the
relevant test file.
Load tests have also been made more accurate, with better function
templates to test register-indexed operations.

This commit expands the implementation of Viper load/store operations
that are optimised for the RV32 platform.
Given the way opcodes are encoded, all value sizes are implemented with
only two functions - one for loads and one for stores. This should
reduce duplication with existing operations and should, in theory, save
space as some code is removed. Both load and store emitters will
generate the shortest possible sequence (as long as the stack pointer is
not involved), using compressed opcodes when possible.

This commit adds two macros that lets check whether a given value can
fit an arbitrary number of bits, either as a signed or as an unsigned
number.
The native emitter code backends perform a lot of bit size checks to see
if a particular code sequence can be emitted instead of a generic one,
and each platform backend has its own ad-hoc macros (usually one per bit
count and signedness).
With these macros there's a single way to perform those checks, plus
there's no more chance for off-by-one mask length errors when dealing
with signed numbers.

CPython math.nan is positive with regards to copysign. The signaling bit
(aka sign flag) was incorrectly set.
In addition, REPR_C and REPR_D should only use the _true_ nan to prevent
system crash in case of hand-crafted floats. For instance, with REPR_C,
any nan-like float following the pattern
`01111111 1xxxxxxx xxxxxxxx xxxxx1xx` would be switched to an immediate
object or a qstr string. When the qstr index is too large, this would
cause a crash.

When the symbol `__all__` is defined in a module, `mp_import_all()` should
import all listed symbols into the global environment, rather than relying
on the underscore-is-private default. This is the standard in CPython.
Each item is loaded in the same way as if it would be an explicit import
statement, and will invoke the module's `__getattr__` function if needed.
This provides a straightforward solution for fixing star import of modules
using a dynamic loader, such as `extmod/asyncio` (see issue #7266).
This improvement has been enabled at BASIC_FEATURES level, to avoid
impacting devices with limited ressources, for which star import is of
little use anyway.
Additionally, detailled reporting of errors during `__all__` import has
been implemented to match CPython, but this is only enabled when
ERROR_REPORTING is set to MICROPY_ERROR_REPORTING_DETAILED.

Any '_' variables/functions in frozen modules are currently printed, when
they shouldn't be. That's due to underscore names possibly existing

matches. The underscore names should be skipped when iterating between the
two boundary qstrs.
The underscore attributes are removed from the extra coverage exp file
because tab completing "import <tab>" no longer lists modules beginning
with an underscore.
