wm4 64b7811c28 x11: when using --wid, inherit event flags from parent window
When embedding a X window, it's hard to control whether it receives
mouse/keyboard input or not. It seems the X protocol itself makes this
hard (basically due to the outdated design mismatching with modern
toolkits), and we have to take care of these things explicitly.

Simply do this by manually querying and using the parent window event
flags.

This restores some MPlayer behavior (it doesn't add back exactly the
same code, but it's very similar).

This probably has some potential to interfere with libmpv embedding, so
bump the client API minor.

CC: @mpv-player/stable (if applied, client-api-changes.rst has to be
    adjusted to include the 0.5.2 release)

Introduction
============
This file lists all changes that can cause compatibility issues when using
mpv through the client API (libmpv and ``client.h``). Since the client API
interfaces to input handling (commands, properties) as well as command line
options, this list is interesting for other uses of mpv, such as the Lua
scripting interface, key bindings in ``input.rst``, or plain command line
usage.
Normally, changes to the C API that are incompatible to previous iterations
receive a major version bump (i.e. the first version number is increased),
while C API additions bump the minor version (i.e. the second number is
increased). Changes to properties/commands/options may also lead to a minor
version bump, in particular if they are incompatible.
The version number is the same as used for MPV_CLIENT_API_VERSION (see
``client.h`` how to convert between major/minor version numbers and the flat
32 bit integer).
Also, read the section ``Compatibility`` in ``client.h``.
