40ad8f1666 all: Rename "sys" module to "usys".
This is consistent with the other 'micro' modules and allows implementing
additional features in Python via e.g. micropython-lib's sys.

Note this is a breaking change (not backwards compatible) for ports which
do not enable weak links, as "import sys" must now be replaced with
"import usys".

3dc324d3f1 tests: Format all Python code with black, except tests in basics subdir.
This adds the Python files in the tests/ directory to be formatted with
./tools/codeformat.py.  The basics/ subdirectory is excluded for now so we
aren't changing too much at once.

In a few places `# fmt: off`/`# fmt: on` was used where the code had
special formatting for readability or where the test was actually testing
the specific formatting.

08c1fe5569 py/vm: Don't add traceback info for exceptions that are re-raised.
With this patch exceptions that are re-raised have improved tracebacks
(less confusing, match CPython), and it makes re-raise slightly more
efficient (in time and RAM) because they no longer need to add a traceback.
Also general VM performance is not measurably affected.

Partially fixes issue #2928.

16f6169c88 py/vm: Don't add traceback info for exc's propagated through a finally.
With this patch exception tracebacks that go through a finally are improved
(less confusing, match CPython), and it makes finally's slightly more
efficient (in time and RAM) because they no longer need to add a traceback.

Partially fixes issue #2928.

566d8f1d7e tests: Make "io" modules fixes for CPython compatibility.
Previously, "import _io" worked on both CPython and MicroPython (essentially
by a chance on CPython, as there's not guarantee that its contents will stay
the same across versions), but as the module was renamed to uio, need to use
more robust import sequence for compatibility.

419bb26ddc tests/print_exception: Use exception which prints the same regardless of config.
NameError may either include offending name or not. Unfortunately, this
change makes test float-dependent. And using integer division leads to
different error message than CPython.

4852e09c79 py: Fix adding of traceback so that it appends to existing info.
This makes exception traceback info self contained (ie doesn't rely on
list object, which was a bit of a hack), reduces code size, and reduces
RAM footprint of exception by eliminating the list object.

Addresses part of issue #1126.

184182d14c tests: Fix print_exception test and re-enable it on Travis CI.
Issue was with uPy: on local machine with micropython-lib installed, io
module is available.  Not the case on Travis CI, where only _io module
is available in uPy.
