This commit provides helpers to retrieve integer values from
mp_obj_t when the content does not fit in a 32 bits integer,
without risking an implicit wrap due to an int overflow.

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.

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.
This commit fixes the issue, and adds the relevant test cases.

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
between the start and end qstrs which are used to print the auto-complete
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.

Previously, there was no test coverage of the "write failed" path. In
fact, the assertion would fire instead of gracefully raising a Python
exception.
Slightly re-organize the code to place the assertion later. Add a test
case which exercises all paths, and update the expected output.

In the case where an mpz number is zero, its `len` is 0 and its `dig` is
NULL. In that case, decrementing NULL via `d--` is undefined behavior
according to the C specification.
Restructuring the loops in this way avoids undefined behavior.
Also, ensure that these cases are tested in the coverage test. This
doesn't make much difference now, but would otherwise cause errors later
when the undefined behavior sanitizer is employed in CI.

This commit factors existing code in `run-tests.py` into a new helper
function `create_test_report()`. That function prints out a summary of the
test run (eg number of tests passed, number failed, number skipped) and
creates the corresponding `_results.json` file.
This is done so `create_test_report()` can be reused by the other test
runners.
The `test_count` counter is now gone, and instead the number of passed plus
number of failed tests is used as an equivalent count.
For consistency this commit makes a minor change to the printed output of
`run-tests.py`: instead of printing a shorthand name for tests that failed
or skipped, it now prints the full name. Eg what was previously printed as
`attrtuple2` is now printed as `basics/attrtuple2.py`. This makes the
output a little longer (when there are failed/skipped tests) but helps to
disambiguate the test name, eg which directory it's in.

This test was factored out from `random_extra.py` back in commit
6572029dc0665e58c2ea7355c9e541bdf83105a4, and the skip logic copied from
that file. But the skip logic needs to test that the `random` and
`uniform` functions exist, not `randint`.
This commit fixes that skip logic.

This commit lets the test runner enumerate and run native tests if the
feature check fails but native tests were explicitly requested from the
command line.
The old behaviour would disable native tests anyway if the feature check
failed, however this hid a bug in the x86 native emitter that would be
triggered even during the feature check. That meant the test suite
would pass on x86 even with a broken emitter, as those tests would have
been skipped anyway.
Now, if the user asks for native code it will get native code out of the
runner no matter what.

Some tests are just too big for targets that don't have much heap memory,
eg `tests/extmod/vfs_rom.py`. Other tests are too large because the target
doesn't have enough IRAM for native code, eg esp8266 running
`tests/micropython/viper_args.py`.
Previously, such tests were explicitly skipped on targets known to have
little memory, eg esp8266. But this doesn't scale to multiple targets, nor
to more and more tests which are too large.
This commit addresses that by adding logic to the test runner so it can
automatically skip tests when they don't fit in the target's memory. It
does this by prepending a `print('START TEST')` to every test, and if a
`MemoryError` occurs before that line is printed then the test was too big.
This works for standard tests, tests that go via .mpy files, and tests that
run in native emitter mode via .mpy files.
For tests that are too big, it prints `lrge <test name>` on the output,
and at the end prints them on a separate line of skipped tests so they can
be distinguished. They are also distinguished in the `_result.json` file
as a skipped test with reason "too large".

Currently the `FrameBuffer.blit(buf, x, y)` method requires the `buf`
argument to be another `FrameBuffer`, which is quite restrictive because it
doesn't allow blit'ing read-only memory/data.
This commit extends `blit()` to allow the `buf` argument to be a tuple or
list of the form:
(buffer, width, height, format[, stride])
where `buffer` can be anything with the buffer protocol and may be
read-only, eg `bytes`.
Also, the palette argument to `blit()` may be of the same form.
The form of this tuple/list was chosen to be the same as the signature of
the `FrameBuffer` constructor (that saves quite a bit of code size doing it
that way).

The `_results.json` output of `run-tests.py` was recently changed in
7a55cb6b364fdbc2f3291456643bd640ba566ec9 to add a list of passed and
skipped tests.
The way this was done turned out to be not general enough, because we want
to add another type of result, namely tests that are skipped because they
are too large.
Instead of having separate lists in `_results.json` for each kind of result
(pass, fail, skip, skip too large, etc), this commit changes the output
form of `_results.json` so that it stores a single list of 3-tuples of all
tests that were run:
[(test_name, result, reason), ...]
That's more general and allows adding a reason for skipped and failed
tests. At the moment this reason is just an empty string, but can be
improved in the future.

This commit expands the Xtensa inline assembler to support most if not
all opcodes available on the ESP8266 and LX3 Xtensa cores.
This is meant as a stepping stone to add inline assembler support for
the ESP32 and its LX6 core, along to windowed-specific opcodes and
additional opcodes that are present only on the LX7 core (ESP32-S3 and
later).
New opcodes being added are covered by tests, and the provided tests
were expanded to also include opcodes available in the existing
implementation. Given that the ESP8266 space requirements are tighter
than ESP32's, certain opcodes that won't be commonly used have been put
behind a define to save some space in the general use case.

The existing test for `math.e` and `math.pi` constants can fail on certain
targets if the functions `math.exp()` and/or `math.cos()` are not accurate
enough (eg out by an LSB of float precision). For example this test
currently fails on PYBD_SF6 which uses double precision floats (and that's
due to the `lib/libm_dbl/exp.c` implementation not being exact).
This commit changes this constant test so that it tests the actual constant
value, not the evaluation of `exp()` and `cos()` functions.

This commit adds a series of test cases to exercise the Viper code
generator load/store emitting capabilities on certain boundary
conditions.
The new test cases check whether the emitted load/store code performs
correctly when dealing with specific memory offsets, which trigger
specific code generation sequences on different architectures.
Right now the cases are for unsigned offsets whose bitmasks span up to
5, 8, and 12 bits (respectively Arm/Thumb, Xtensa, RV32).

This commit makes the JSON parser raise an exception when handling
objects or arrays whose declaration is incomplete, as in missing the
closing marker (brace or bracket) and if the missing marker would have
been the last non-whitespace character in the incoming string.
Since CPython's JSON parser would raise an exception in such a case,
unlike MicroPython's, this commit aligns MicroPython's behaviour with
CPython.
This commit fixes issue #17141.
