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.

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.

Remove the unused `nevents` parameter from `uv__async_event()`
and remove the indirection of having a separate `uv__async`
type. There is only one instance per event loop these days.
This incidentally removes the `assert(n == sizeof(val))` in a
Linux-specific code path that some users seem to hit from time
to time. The cause is not well-understood and I've never been
able to reproduce it myself. Presumably libuv gets an EAGAIN
when trying to read from the eventfd but when and why that
happens is unclear.
Since the byte count is unused, removing the assert seems safe.
Worst case, libuv sometimes iterates over the async watcher list
when it doesn't have to.

This patch enables querying and setting the process title on AIX.
libuv takes ownership of the memory for argv and returns a deep copy
of the array and its contents.
It also enables the process_title test case.
The process title can be changed on AIX but is handled differently
to Linux/Mac. Commands like ps read the original argv array passed
to the process instead of the memory at argv[0]. To change the process
title we need to update argv[0] to point at a new string and set
argv[1] to NULL (if it exists). This means the process title
can be set to a string of any length.
