- Remove the `active_reqs` queue, which is never used. There are more
efficient per-stream queues that `libuv` uses whenever it needs this
information, so duplicating it and managing it here seems
like unnecessary extra space and work.
- Unix `uv_loop_init` didn't explicitly initialize.
`loop->active_handles` (although it did memset the whole struct
to 0, so it wasn't wrong previously, just inconsistent).
- Consolidate repeated code for `uv__has_active_reqs`.
- Change `uv__loop_alive` to use the helper functions (mirroring the
unix copy of the same function).
- Initialize some more uv_stream_t fields in init, rather than waiting
for the connection callback. This helps surface bugs in libuv or the
caller better, since it ensures libuv doesn't see uninitialized
memory if asked to look at these fields before it thinks the socket
is connected.
- Fixes what appears to be a double-counting of `handle->reqs_pending`,
in the highly-unlikely event that the code wants to emulate IOCP,
but `RegisterWaitForSingleObject` somehow managed to fail.

Using -errno, -E**, and -pthread_function() can be
error prone, and breaks compatibility with some operating
systems that already negate errno's (e.g. Haiku).
This commit adds a UV__ERR() macro that ensures libuv

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.

Add getter/setter functions for the fields of public structs that
might be relevant to e.g. Node.js addons.
Through these methods, ABI compatibility for a subset of the ABI
is easier to achieve, since using them makes code independent
of the exact offsets of these fields.
The intended use case that prompted this are N-API addons for
Node.js, which look for more long-term ABI compatibility guarantees
than typical Node code. With these helper functions, using libuv
directly should no longer be an obstacle for such addons.

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.

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

Added the uv_loop_fork() API that must be called in a child process to
continue using an existing loop. Internally this calls a uv__io_fork
function for each supported platform, similar to the way
uv__platform_loop_init works.
After this call, existing and new IO, async and signal watchers will
contiue working as before on all platforms, as will the
threadpool (although any threads it was using are of course gone).
On Linux and BSDs that use kqueue, existing and new fsevent watchers
will also continue to work as expected. On OS X, though, directory
fsevents will not be able to use the optimized CoreFoundation path if
they had already been used in the parent process, instead falling back
to the kqueue path used on other BSDs.
Existing fsevent watchers will not function on AIX or SunOS. This
could be relatively easily fixed by someone with AIX knowledge in the
future, but SunOS will require some additional work to keep track if
the watchers.
A new test file, test/test-fork.c, was added to contain fork-related
tests to verify functionality in the child process.
