Ned Konz 5543b2a9cc extmod/uasyncio: Add clear method to ThreadSafeFlag.
This is useful in situations where the ThreadSafeFlag is reused and needs
to be cleared of any previous, unwanted event.

For example, clear the flag at the start of an operation, trigger the
operation (eg an I2C write), then (a)wait for an external event to set the
flag (eg a pin IRQ).  Further events may trigger the flag again but these
are unwanted and should be cleared before the next cycle starts.

Lars Kellogg-Stedman 8f6924c9fb docs/library/uasyncio.rst: Fix description of ThreadSafeFlag.wait.
When a task waits on a ThreadSafeFlag (and the wait method returns), the
flag is immediately reset.  This was not clear in the documentation, which
appeared to copy the description of the wait method from the Event class.

Mike Teachman b0b8ebc4f6 extmod/uasyncio: Add readinto() method to Stream class.
With docs and a multi-test using TCP server/client.

This method is a MicroPython extension, although there is discussion of
adding it to CPython: https://bugs.python.org/issue41305

Zenix27 e76c7466b6 docs: Change `\*` to `*` in argument lists.
Latest versions of Sphinx (at least 3.1.0) do not need the `*` escaped and
will render the `\` in the output if it is there, so remove it.

Fixes issue #6209.

Damien George db137e70dc extmod/uasyncio: Add Loop.new_event_loop method.
This commit adds Loop.new_event_loop() which is used to reset the singleton
event loop.  This functionality is put here instead of in Loop.close() to
make it possible to write code that is compatible with CPython.
