This fixes a regression by 69d81540
Originally this used GdipAlloc (calloc)

Fixes a regression from 1d337249.

Prior to the commit, we were solving this case in a different way.
If IDropTarget::DragOver() returned DROPEFFECT_NONE,
X11DRV_XDND_DROPEFFECTToXdndAction() would convert it to XdndActionCopy.

The is_window_managed function may acquire the (non-recursive) win_data lock
internally (is_window_managed->has_owned_popups->is_managed), so do not call
it with the win_data lock held.

When running `wine explorer.exe /desktop=shell` as a full-screen app,
there is no obvious way to close it and return to the Linux desktop.
Remedy that problem by adding an "Exit desktop" button to the Start menu
in the same place as the "Shut Down" button on Windows.

When we have a Vulkan client subsurface, and depending on timings and
window state (e.g., fullscreen), we may not get the chance to apply new
surface configurations when presenting content to the main window
surface. To ensure new configurations are applied, also check for and
apply/ack configurations during Vulkan presentation.

This fixes some games which resize when they become fullscreen, but are
not properly placed by the compositor, because they never ack the
fullscreen state.

The WM_SETFONT was previously passing the hFont as the LPARAM (when it
should be the WPARAM).

This fixes the layout of the tabcontrol when a font other than the
system font is used.

Windows sets the default width to LOGPIXELSX regardless of the style.

It will also always return the previous cx value provided.

To avoid triggering pointer-truncation bugs in applications.

Explicitly enable the few programs that need it.

Whilst uniscribe won't break on the space here (see LB13 of the Unicode
line breaking algorith), DrawText does

Make sure we poll queries before we go to sleep, to e.g. avoid hangs
in Rocket League.

For h264 byte-stream format, we should set "streamheader".
"codec_data" is for avc.

We also set timestamp of the buffer to 0 because
mp4mux will be error if the PTS is none.

Rewrite needs this.
