Damien George 4b72b3a133 py: Change type signature of builtin funs that take variable or kw args.
With this patch the n_args parameter is changed type from mp_uint_t to
size_t.

Paul Sokolovsky c1481bb0ab unix/moduselect: Implement "one-shot" flag for poll.poll().
After an I/O event is triggered for fd, event flags are automatically reset,
so no further events are reported until new event flags are set. This is
an optimization for uasyncio, required to account for coroutine semantics:
each coroutine issues explicit read/write async call, and once that trigger,
no events should be reported to coroutine, unless it again explicitly
requests it. One-shot mode saves one linear scan over the poll array.

Paul Sokolovsky 082b12128d unix/moduselect: register(): Allow to call with duplicate file descriptor.
Per CPython docs, "Registering a file descriptor that’s already registered
is not an error, and has the same effect as registering the descriptor
exactly once."
https://docs.python.org/3/library/select.html#select.poll.register

That's somewhat ambiguous, what's implemented here is that if fd si not
yet registered, it is registered. Otherwise, the effect is equivalent to
modify() method.

Damien George 999cedb90f py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.

This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.
