Calculate ~POLLIN and ~POLLOUT as constants to remove the runtime cost
of continuously calculating them. And unpack the queue entry rather than
using repeated item lookups.
If the main task is interrupted by e.g. a KeyboardInterrupt, then the
main task needs to have the exception injected into it so it will run
the exception handlers and contextmanager __aexit__ methods.
Adds support to asyncio.gather() for the case that one or more (or all)
sub-tasks finish and/or raise an exception before the gather starts.

Sometimes these are different file descriptors, not to mention the Unix
port, so use stderr to distinguish these error messages.
CPython prints to stdout, but it does it via a call to the logging module.
We don't want to introduce a dependency on logging, so printing to stderr
is a good alternative. One can override default_exception_handler() if
needed.
The asyncio module now has much better CPython compatibility and
deserves to be just called "asyncio".
This will avoid people having to write `from uasyncio import asyncio`.
Renames all files, and updates port manifests to use the new path. Also
renames the built-in _uasyncio to _asyncio.
