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.

We use the UV_HANDLE_BOUND flag to mark a socket as bound to a
port. We need to do this for sockets that are sent from another
process as well as sockets that created by the process itself.
First check if the port number is non-zero. If yes then mark
it as bound.

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.

Like the previous commit, except now the signal mask is reset instead
of the signal disposition. This does open a race window where blocked
signals can get delivered in the interval between the pthread_sigmask()
call and the execve() call (and may end up terminating the process) but
that cannot be helped; the same caveat applies to the previous commit.

Signal dispositions are inherited by child processes. Libuv itself
does not touch them (if you don't use uv_signal_start(), that is)
but the embedder might and probably does in the case of SIGPIPE.
Reset the disposition for signals 1-31 to their defaults right before
execve'ing into the new process.

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.

The contract specifies that the file descriptor should already be in
non-blocking mode before passing it to libuv.
However, node users don't really have an opportunity to do so, never
mind the fact that the call to uv_pipe_open() or uv_tcp_open() is an
implementation detail that most users won't be aware of.
Let's be nice and set the non-blocking flag explicitly. It's a cheap
operation anyway.

Fix spawn_reads_child_path when executed as `test/run-tests` or
`make check`:
1. `make check` builds a dynamic libuv.so or libuv.dyld by default.
2. spawn_reads_child_path spawns a new instance of the test runner
by consulting uv_exepath() and executing the result.
3. `test/run-tests` is normally a shell script that sets up
DYLD_LIBRARY_PATH or LD_LIBRARY_PATH before executing the
real test runner in `test/.libs`.
4. uv_exepath() (corectly) returns the path of the binary in
`test/.libs`. The binary is linked against libuv.so but that
library is not on any of the default linker paths; and if it is,
it's almost certainly the wrong version.
5. Ergo, carry over the value of the (DY)LD_LIBRARY_PATH environment
variable into the environment of the child process so that the
dynamic linker knows where to find the library.
Alternatively, we could link the test runner statically against libuv.a
but that breaks `make check` when configured with `--disable-static`.

The unix and windows process implementations diverge in their behavior
when dealing with subprocesses that are spawned with a relative path.
With unix the *child's* PATH environment variable is read, whereas
with windows the *parent's* environment variable is read.
This commit brings the two implementation in line with respect to
their behavior of reading PATH by having both read the *child's* PATH
environment variable. This involves looking into the user-provided
environment on windows and extracting the PATH variable specifically
so it can be inspected later on.
The PATH-parsing code for windows erroneously contained an infinite
loop when the PATH started with a leading semicolon. Each iteration of
the loop usually bumped over the separator, but if the first character
was a semicolon then it would never skip it, causing the infinite
loop.
Closes#909
