While working on adding 0o and 0b literals (which aren't added yet and
may not be) I realized that my approach would likely cause a problem
for the value "0"
* use a virtual fat filesystem during the test
* this makes the file I/O part more closely patch runtime which is nice
* side-steps the need to add a special function for testing
* but test still can't be run on a device, because the vfs calls
are incompatible, and you intentionally can't remount "/" anyway
* and side-steps problems with storing 'bad' toml files
The assertion that is added here (to gc.c) fails when running this new test
if ALLOC_TABLE_GAP_BYTE is set to 0.

The code was already checking for duplicate kwargs for named parameters but
if `**kwargs` was given as a parameter, it did not check for multiples of
the same argument name.
This fixes the issue by adding an addition test to catch duplicates and
adds a test to exercise the code.
Fixes issue #10083.

This test could occasionally fail because some operations take longer
than expected. This relaxes the timing constraints and defers printing
until the very end.

Now that the Timer class has been merged in a separate pull request,
this can be added to the module test too.

Implements dictionary union according to PEP 584's specifications, minus
the fact that dictionary entries are not guaranteed to be in insertion
order. This feature is enabled with MICROPY_CPYTHON_COMPAT.
Includes a new test.

This shows how ports can add their own custom types/classes.
It is part of the unix coverage build, so we can use it for tests too.

This will make mpy-cross auto-detect. Allow overriding for non-default
configurations (e.g. using 32-bit build of the unix port).
Also use armv7m by default for qemu-arm (the default qemu target is
Cortex-M3).

This adds the __cause__, __context__ and __suppress_context__
members to exception objects and makes e.g., `raise exc from cause`
set them in the same way as standard Python.
This prevents a very subtle bug caused by writing e.g. `bytearray('\xfd')`
which gives you `(0xc3, 0xbd)`.

A task that has been sent to the loop's exception handler due to being
re-scheduled twice will then subsequently cause a `raise None` if it is
subsequently awaited. In the C version of task.py, this causes a segfault.
This makes the await succeed (via raising StopIteration instead).

This also depends on https://github.com/adafruit/Adafruit_CircuitPython_Ticks/pull/8
otherwise adafruit_ticks is unimportable and the tests are just skipped.
Several of the tests fail, and one runs forever instead of terminating.
We should fix our asyncio until the tests patch, then incorporate this
change.
Gives the absolute path to the unix micropython binary.

.. it needs to operate on a FILE* rather than FIL depending on
the build.
Note that this is comparing output to expected, not to cpython dotenv
package. Because run-tests.py starts the CPython interpreter with the
'-S' (skip site initialization) flag, pip-installed packages are
not available for import inside a test file. Instead, the exp
file is generated manually:
```
circuitpython/tests$ python3 circuitpython/dotenv_test.py > circuitpython/dotenv_test.py.exp
```
Unfortunately, the test fails on test e15:

Allows optimisation of cases like:
import micropython
_DEBUG = micropython.const(False)
if _DEBUG:
print('Debugging info')
Previously the 'if' statement was only optimised out if the type of the
const() argument was integer.
The change is implemented in a way that makes the compiler slightly smaller
(-16 bytes on PYBV11) but compilation will also be very slightly slower.
As a bonus, if const support is enabled then the compiler can now optimise
const truthy/falsey expressions of other types, like:
while "something":
pass
... unclear if that is useful, but perhaps it could be.
