[PATCH 0/2] user32: Change GetKeyState() / GetKeyboardState() to fix some programs.

[Markus Engel]

Hi,
the documentation for these two functions isn't clear about the contents
of the bits of the return value, except the highest and lowest bit. Some
programs assume that these are always set to zero, which seems to be the
actual behavior in Windows.

Specifically, this leads to stuck keys in "Age of Empires 2 HD" and "Age
of Empires 2: Definitive Edition" when tabbing out as reported in
https://bugs.winehq.org/show_bug.cgi?id=30814 .

The following patch makes sure that all undefined bits are set to zero.
