Libuv is not supported on Windows XP, as stated in the
SUPPORTED_PLATFORMS document. It also can't possibly work because
`ReOpenFile()` in src/win/fs.c is not weakly linked, so any executable
that links libuv would simply fail to load on XP.
This reverts commit 17eaa956bd.

* Don't silently ignore ERROR_OPERATION_ABORTED.
Code to silently ignore this error was added in c42a4ca, under the
false premise that this error is somehow equivalent to EINTR on posix
platforms. This isn't true; ERROR_OPERATION_ABORTED doesn't happen
unless the application explicitly aborts an I/O operation.
Silently ignoring this error elsewhere could potentially hide bugs,
hence libuv shouldn't do it. Instead, explicitly deal with it where
it is expected.
* Don't mark aborted reads as successful.
The worker thread used to call ReadFile() on synchronous pipes would
incorrectly mark cancelled read requests as successful, leading to
issues later on.
* Rely on main thread to restart aborted reads.
After a blocking ReadFile() call was cancelled, the worker thread
would previously attempt to restart it immediately, making
synchronization logic needlessly complex. Instead, we simply cancel
the operation, and leave it to the main loop to restart it if so
desired.
Since we now realy on the main thread to restart interrupted
ReadFile() calls, we can now have a single function interrupts a
synchronous read until the event loop restarts it again.
* Clean up uv__pipe_read_stop().
A single function to interrupt blocking reads also allows us to
remove weird logic in uv__pipe_read_stop() that quickly pauses and
unpauses a read operation in the hope of cancelling it.
* Assume CancelIo() and CancelSynchronousIo() are always available.
Since libuv doesn't support windows XP and Server 2003 any more, we
can assume that these APIs are always available, and do away with
branching around them.

The Reg* APIs on Windows don't use GetLastError() to report
failures. The errors are returned directly from the call.
For systems which don't have one of the values GetLastError() can
end up returning 0 to the caller, indicating success. The caller
then assumes that the data is valid and can attempt to execute on
garbage data. This change fixes the flow to correctly return the
error to the caller.

This commit refactors uv_os_homedir() to to use uv_os_getenv()
to retrieve the USERPROFILE environment variable. This removes
a fair amount of duplicated code, while introducing the following
changes:
1. The function no longer returns UV_EIO when USERPROFILE is
longer than MAX_PATH. This can be reinstated by adding a
check for r == 0 && *size >= MAX_PATH.
2. The USERPROFILE string is now a char*, meaning that it must
be converted from utf8 to utf16 by uv_os_getenv().

- 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.
