This code already had special handling for decoding utf-8
characters correctly for the UCS-2 conhost
(trailing incomplete bytes and characters > 0xFFFF).
Rather than trying to duplicate that, we can simply
delete the duplicate code-path and selectively disable
the parts that do not apply.

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.

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.

The tty subsystem on Windows was listening for console events from all
processes to detect when our console window was being resized. This
could cause an explosion in the number of events queued by the system
when running many console applications in parallel that all wrote to
their console quickly. The end result was a complete machine hang.
Now we determine, whenever possible, what our corresponding conhost.exe
process is and listen for console events from that process only. This
detection does not work in 32-bit applications running on 64-bit
Windows so those default to the old behavior of listening to all
processes.

The MSVC runtime provides a global variable that can be used to set the
default file translation mode so that file open calls don't need to
explicitly specify that mode.
libuv was changing that global mode to binary from its default of text.
However, libuv doesn't actually need to do that anymore, and the
application may not want the default changed under it. This change stops
libuv from modifying that global mode.
