test: silence more valgrind warnings (#3917)

Pass the loop to MAKE_VALGRIND_HAPPY() so it's explicit on which loop
needs to be cleaned up. Since it asserts on uv_loop_close(), need to
remove a couple of those that were being done before the call.

Cleanup where loop was assigned, so the entire test either uses loop or
uv_default_loop(). Not both.

Also take care of any reqs that may have been left uncleaned.

test: skip self-connecting tests on cygwin

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.

cygwin: implement support for cygwin and msys2

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.

test: fix POLLHDRUP related failures for AIX

`POLLHDRUP` is not implemented on AIX. Therefore `UV_DISCONNECT` will
never be set on `events`. This causes the socket to never be closed and
the tests to be stuck inside `pollset_poll` indefinitely, resulting in a
timeout.

This fixes the following tests:
- poll_duplex
- poll_unidirectional

Updated docs to let end users know that `UV_DISCONNECT` can be set, but
is unsupported on AIX.

Libuv would abort() when trying to watch a file descriptor that is

to on-disk files fall into this category.

File descriptors that libuv creates itself are not an issue but
external ones that come in through the uv_poll_init() API are.

Make uv_poll_init() check whether the file descriptor is accepted by
the underlying system call and return an error when it's not.
