Killing explorer breaks later tests. We can create a new desktop
without a shell instead.

WM_DEVICECHANGE's lParam can be either a pointer to a variant of
DEV_BROADCAST_HDR or an immediate value (usually 0) depending on
the wParam's value.
This fixes a crash when broadcasting WM_DEVICECHANGE with
wParam = DBT_DEVNODES_CHANGED, lParam = 0.

get_display_dc() may be locking display_dc_section at the end of
user driver initialization in LoadCursorA() called from
register_builtin_classes(). If the driver initialization initiated
in CreateDCW() goes in parallel with the initialization started
elsewhere without holding display_dc_section, the process can deadlock.
Fixes random lockup on start in Hammerting.

Having a __wine_display_device_guid property in the desktop window only guarantees that the window
is created. Explorer.exe still has to finish setting up virtual desktop, display settings etc.
load_desktop_driver() needs to make sure that the desktop initialization is done before allowing
applications to call user32 driver functions. Otherwise, they might get incorrect data. This race
condition became apparent after aadae4d1ea, which adds ~100ms to the
initialization process.

EnumDisplaySettings() on Wine does not write beyond the end of DEVMODE because it doesn't use
dmDriverExtra currently, but this implementation detail should not be relied on.

This fixes a regression introduced by
08bf605acb.
It could lead to stack corruption because ret can be negative when the
output position, p, doesn't point the beginning of the buffer before
the inner loop.
