755b01439b unix: machine_mem improvements
This basically introduces the MICROPY_MACHINE_MEM_GET_READ_ADDR
and MICROPY_MACHINE_MEM_GET_WRITE_ADDR macros. If one of them is
not defined, then a default identity function is provided.

2eb844e0b4 ports: Rename "machine" module to "umachine".
To let unix port implement "machine" functionality on Python level, and
keep consistent naming in other ports (baremetal ports will use magic
module "symlinking" to still load it on "import machine").

Fixes #1701.

3db2b23060 unix/unix_mphal: Properly initialize struct sigaction.
This solves long-standing non-deterministic bug, which manifested itself
on x86 32-bit (at least of reported cases) - segfault on Ctrl+C (i.e.
SIGINT).

d874702fe1 unix/modos: Implement ilistdir().
ilistdir() returns iterator which yields triples of (name, type, ino)
where ino is inode number for entry's data, type of entry (file/dir/etc.),
and name of file/dir. listdir() can be easily implemented in terms of this
iterator (which is otherwise more efficient in terms of memory use and may
save expensive call to stat() for each returned entry).

CPython has os.scandir() which also returns an iterator, but it yields
more complex objects of DirEntry type. scandir() can also be easily
implemented in terms of ilistdir().

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.

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.

5ae3ddcc9a unix/main: Check pending exception at the end of code block execution.

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.

0bb57bf5bf unix/modtime: sleep(): Automatically restart after receiving EINTR.
THis is required to deal well with signals, signals being the closest
analogue of hardware interrupts for POSIX. This is also CPython 3.5
compliant behavior (PEP 475).

The main problem implementing this is to figure out how much time was
spent in waiting so far/how much is remaining. It's well-known fact that
Linux updates select()'s timeout value when returning with EINTR to the
remaining wait time. Here's what POSIX-based standards say about this:
(http://pubs.opengroup.org/onlinepubs/9699919799/functions/pselect.html):

"Upon successful completion, the select() function may modify the object
pointed to by the timeout argument."

I.e. it allows to modify timeout value, but doesn't say how exactly it is
modified. And actually, it allows such modification only "upon successful
completion", which returning with EINTR error hardly is.

POSIX also allows to request automatic EINTR restart for system calls using
sigaction call with SA_RESTART flag, but here's what the same document says
about it:

"If SA_RESTART has been set for the interrupting signal, it is
implementation-defined whether the function restarts or returns with
[EINTR]."

In other words, POSIX doesn't leave room for both portable and efficient
handling of this matter, so the code just allows to manually select
Linux-compatible behavior with MICROPY_SELECT_REMAINING_TIME option,
or otherwise will just raise OSError. When systems with non-Linux behavior
are found, they can be handled separately.

inet_ntop() function. At the very least, sockaddr() will separate address
family value from binary socket address (and currently, only AF_INET family
is decoded).

f_ffree, f_favail, f_flag, f_namemax. This is exactly the order described
