It allows setting the child process' CPU affinity mask.
Implement it on Linux, FreeBSD, and Windows for now, and fail with
UV_ENOTSUP on other platforms.

This commit uses the Register File Interest feature on z/OS
to enable users to monitor file system events.
The poll call is used to check for file descriptors as well
as a message queue that z/OS will report file system events
on. The last item on the list used by poll will contain the
message queue id instead of a file descriptor.
Limitation:
Writes to a directory (that is, file creation and deletion)
do not generate a change message for a registered directory.

Since on Windows HANDLEs are not the same as file descriptors,
confusing the two meant that almost all APIs in libuv had to go through
a thin compatibility layer, adding needless complication.
This removes that layer of external indirection and instead
works with the native Win32 API directly.

The cygwin runtime library fails to connect a socket client to a
listening server within the same thread. Test cases that use
this approach hang while waiting for the connection to complete.
This can be reproduced independent of libuv in a simple example
using both socket/bind/listen and socket/connect in a single
thread.
Avoid this problem in our test suite by skipping such tests on cygwin.

On Cygwin `recvmsg` always sets `msg_controllen` to zero on a
message received from a named pipe. Therefore we cannot use
`sendmsg` to send handles for ipc. Return failure early from
this code path as `ENOSYS`.
Skip tests requiring this feature since it is not available.

Cygwin and MSYS2 are POSIX layers implemented on top of Windows.
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
due to Cygwin platform limitations or our placeholders.

On Windows the pipe implementation could read more from a stream than
was available and it would create an assertion failure. This change
will make it so we read the minimum of the available data or the length
of the data.
To test this, I took the existing ipc_send_recv_tcp test and updated it
to do two writes and two read on each side of the pipe since that was the
reproduction recipe used by the reporter. This approach reproduced the
issue on Windows and the committed fix resolved the issue.

Should fix the build after 96f32a2 inadvertently broke it.
There is no snprintf() on Windows because, hey, it's a C99 addition
and the people from Redmond, WA are still firmly stuck in 1989.
Switch to the build tool everyone loves to hate. The Makefile has
served us well over the years but it's been acquiring more and more
features that autotools gives us for free, like easy static+shared
library building, sane install targets, and so on.
This commit drops MinGW support. If there is demand for it, we'll
re-add it.
They're BSD-isms and obsolete ones at that. Replace with S_IRUSR and
S_IWUSR. Alias as _S_IREAD and _S_IWRITE on Windows because the '90s
never ended in Redmond, WA.
Added two new flags to identify tests that are intentionally ignored
(usually because we don't want to implement the tested functionality
on current platform) and test serving as TODO list (usually indicating
that the tested functionality should be implemented on current plaform
in the near future.)
Replace `void f()` with `void f(void)`; the former means "a function
that takes any number of arguments, including none" while the latter
is what is actually intended: a function taking no arguments.
The first form also isn't strictly conforming ANSI/ISO C.
Based on UNIX sockets to avoid the vagaries of FIFOs
in asynchronous mode. Currently unlinks stale sockets
before binding and cleans them up again after shutdown.
