There are some special environment variables on Windows that
start with a '=' sign, e.g. per-drive working directories.
In those cases, an initial '=' in the name of the environment
variable needs to be skipped when looking for the '=' that separates
it from its value.

unix: fix UV_FS_O_DIRECT definition on Linux

According to http://man7.org/linux/man-pages/man2/open.2.html, the
O_DIRECT flag is Linux-specific. One must define _GNU_SOURCE to obtain
the correct definition.

However, defining _GNU_SOURCE in the headers is unhygienic and affects
the libuv consumer.

On Linux, we now define UV_FS_O_DIRECT explicitly according to
architecture, only falling back to O_DIRECT if defined, or 0 if not.

unix: simplify open(O_CLOEXEC) feature detection

Platforms that support O_CLOEXEC have supported it for a long time
and don't need feature detection. Libuv can just assume it works as
advertised.

The feature detection was broken for old Linux kernels because they
don't report EINVAL for unknown open() flags, they simply open the
file without setting the FD_CLOEXEC flag.

Libuv could fix that by checking afterwards with fcntl() if the flag
was actually set but it doesn't support kernels that old in the first
place so let's simplify the logic.

aix: Fix broken cmpxchgi() XL C++ specialization.

The preprocessor was used to select a special implementation when
building on AIX using XL C++ (strangely, not XL C). This code
implemented `cmpxchgi()` by directly reading the old value and then
calling `__compare_and_swap()`, an intrinsic that does not provide
any sort of memory barrier guarantees. The return value was not
used, and the value read prior to the `__compare_and_swap()` call
was returned. There is no way that this code could provide the
required semantics of the function and it causes observable data
races and strange library failures in production under load.

XL C/C++ for AIX has provided support for the GCC intrinsic used in
the GCC/Clang cases since version 12.1 of the compiler. This
version of the compiler is old enough that it doesn't warrant a
version check. (The compiler was released 8-Jun-2012, maintenance
ended 9-Jul-2019, and service ends 30-Apr-2020.)

This change fixes all observed atomic issues and unifies XL C/C++
with GCC/Clang.

win, tty: improve SIGWINCH performance

Continuing improvement of SIGWINCH from PR #2308.

Running SetWinEventHook without filtering for the specific PIDs has
significant impact on the performance of the entire system. This PR
changes the way SIGWINCH is handled.

The SetWinEventHook callback now signals a separate thread,
uv__tty_console_resize_watcher_thread. This thread calls
uv__tty_console_signal_resize() which checks if the console was actually
resized. The uv__tty_console_resize_watcher_thread makes sure to not to
call the uv__tty_console_signal_resize function more than 30 times per
second.

The SetWinEventHook will not be installed, if the PID of the
conhost.exe process that owns the console window cannot be
determinated. This can happen when a 32bit libuv app is running on a
64bit Windows.

For such cases PR #1408 is partially reverted - when tty reads
WINDOW_BUFFER_SIZE_EVENT, it will also trigger a call to
uv__tty_console_signal_resize(). This will also help when the app is
running under console emulators. Documentation was also updated to
reflect that.
