uasyncio.core: Fix scheduling in the presense of I/O completion callbacks.
...
wait() may finish prematurely due to I/O completion, and schedule new,
earlier than before tasks to run. So, after call to wait(), we need to
check current time and time of head task, and continue to wait if needed.
Recently introduced provisional utimeq.peektime() is used to optimize
querying time of a head task.

uasyncio.core: Set lower default queue len and allow to override it.
...
The default is set to be under 0.5K on 32-bit system. A queue length
can be passed to get_event_loop() to override it.

uasyncio.core: Implement sleep_ms as an awaitable object instead of coro.
...
This allows to await it without heap allocation.

uasyncio.core: Switch to dedicated utimeq class.
...
Allows zero-allocation scheduling of tasks. As long as tasks don't use
await/yield from with coroutines, and don't allocate memory themselves,
there will be no allocation and GC.

uasyncio.core: Add additional debug output control.
...
__debug__ isn't flexible enough, if you don't disable it, there's huge
memory allocation.

uasyncio.core: Introduce "trailing _" functions which avoid arg un/packing.
...
They just take tuple of arguments instead of *args. In most cases, that
will be () singleton.

uasyncio.core: call_soon(): Use current time, not zero time.

Using static zero time may become a problem when using wrap-around time

uasyncio.core: Optimize case of resuming coro with no args.
...
Don't create a new tuple with empty arguments for coro.send(), just use
next(coro).

uasyncio.core: async() was renamed to ensure_future() upstream.
...
The old name is deprecated since CPyton 3.4.4. That's great relief, because
CPython has special parser hacks to support both 3.5-style "async" keyword,
and still allow it be used as an identifier in other contexts. MicroPython
lacks such hacks, so "async" is SyntaxError as a function name with the latest
versions which implement async keyword.

uasyncio.core: Avoid wrapping coroutines to lambdas for add_reader/writer.
...
add_reader/writer default behavior is to schedule "callback" on I/O
completion via call_soon(), there's no need to have lambda for that.

uasyncio.core: Don't pass any callback args to add_reader/add_writer.
...
Instead, capture all needed param in closure. Due do bug in MicroPython's
handling of default args to lambdas, helper function is used.
