Out-of-band TCP messages are used for TCP data
transmission outside (outband) the inbound TCP
data. These packets are sent with an
"urgent pointer", but previously discarded.
Additionally, when using (e)poll a POLLPRI is
triggered when an interrupt signal is received
on GPIO capable systems such as the Raspberry Pi.

The uv__get_osfhandle() function is a private functio of the
Windows subsystem, and its used to get a Windows HANDLE out
of a file descriptor number.
The motivation behind making this function public is to
allow Node.js programs to pass file descriptors created
using fs.open() to native Node.js C++ add-ons, and be able to
successfully convert them to Windows HANDLEs.

Use our POSIX `poll(2)` implementation of our poll abstraction.
For most other components we already have dedicated sources
implementing them in terms of APIs available on Cygwin or
providing non-implementations of components not supported.
This leaves only three components that need Cygwin-specific
implementations:
* uv_uptime: implement using sysinfo
* uv_resident_set_memory: add a placeholder returning UV_ENOSYS
* uv_cpu_info: add a placeholder returning UV_ENOSYS
Update our test suite to account for features not available

This commit adds an equivalent function on other platforms, and

It can happen that the `parent` end of the `signal_pipe` is given a
STDIO file descriptor, so closing it using `uv__close` fails.
This problem is happening when running the `spawn_closed_process_io`
test in `SmartOS`. The reason being that when creating a socketpair in
`uv__process_init_stdio`, the `Illumos` implementation uses 3 sockets:
one is used as a listener, and the other 2 represent both ends of the
pipe. The listener socket is closed once the pipe is created. In the
test, the listener socket is assigned to the `0` fd, as it is the
first free fd in the system. So the fd `0` remained free after the call
to `socketpair`. Afterwards, when creating the `signal_pipe`, the fd `0`
is being assigned again, so closing it with `uv__close` made the test
fail. This issue is not happening in the other unixes because
`socketpair` doesn't use 3 fd's, but only 2.
To solve the issue, a new `uv__close__nocheckstdio()` function has been
added and used.

As far as I have been able to establish, dup2 and dup3 never return
EINTR on OS X and FreeBSD. Even if other platforms do return EINTR,
it's probably still better not to retry because it's unspecified
whether the file descriptor has been closed.

Retrying seems like a bad idea in a multi-threaded program because the
man page leaves it unspecified whether the file descriptor is closed
after EINTR.
It's probably an academic issue because as far as I have been able to
establish by checking the kernel sources, dup2 and dup3 never actually
return EINTR. For dup3, this appears to have been the case since its
introduction in v2.6.27; for dup2, it goes back to at least v2.6.18.

Returns the platform specific file descriptor for handles that are
backed by one. The datatype is abstracted as uv_os_fd_t, which maps to
int on Unices and HANDLE on Windows.
Users can use this function to set specific socket options, for example,
in a non portable way.
This function is essentially a shotgun, you better be careful with
whatever you do with it, don't blame me if you used it to get the fd of
a stream, close it yourself and expect things to Just Work.
