Jim Mussared b22abcdbbe extmod/uasyncio: Handle gather with no awaitables.
This previously resulted in gather() yielding but with no way to be
resumed.

Damien George c90f097519 tests/extmod: Increase timing on uasyncio tests to make more reliable.
Non-real-time systems like Windows, Linux and macOS do not have reliable
timing, so increase the sleep intervals to make these tests more likely to
pass.

Damien George 28e7e15c0a extmod/uasyncio: Fix bug with task ending just after gather is cancel'd.
This fixes a bug where the gather is cancelled externally and then one of
its sub-tasks (that the gather was waiting on) finishes right between the
cancellation being queued and being executed.

Damien George ef1c2cdab0 tests/extmod/uasyncio_gather: Make double-raise gather test reliable.
This double-raise test could fail when task[0] raises and stops the gather
before task[1] raises, then task[1] is left to raise later on and spoil the
test.

Damien George 90aaf2dbef extmod/uasyncio: Fix gather cancelling and handling of exceptions.
The following fixes are made:
- cancelling a gather now cancels all sub-tasks of the gather (previously
  it would only cancel the first)
- if any sub-task of a gather raises an exception then the gather finishes
  (previously it would only finish if the first sub-task raised)

Fixes issues #5798, #7807, #7901.

Damien George 06659077a8 all: Update Python code to conform to latest black formatting.
Updating to Black v20.8b1 there are two changes that affect the code in
this repository:

- If there is a trailing comma in a list (eg [], () or function call) then
  that list is now written out with one line per element.  So remove such
  trailing commas where the list should stay on one line.

- Spaces at the start of """ doc strings are removed.

Damien George c4935f3049 tests/extmod: Add uasyncio tests.
All .exp files are included because they require CPython 3.8 which may not
always be available.
