Previously, callbacks were called with a critical section held. It was
intended that monitor handles passed to callbacks should always be valid.
But it created a deadlock condition when callbacks call other functions
which try to grab the critical section using a different thread. Tests
also show that a monitor handle can be invalid after a display change.
So do not hold the critical section when calling callbacks. Monitor
handles will be checked when passed to GetMonitorInfo(), which is the
sole function that consumes HMONITORs.

test_ChangeDisplaySettingsEx() can generate so many posted messages
for display change events that USERPostMessageLimit is reached and
ERROR_NOT_ENOUGH_QUOTA is returned for PostMessage(). Call flush_events()
after mode changes to limit message post rate.

Halo: Spartan Strike attempts to discover input devices using rawinput. It
expects to be able to open at least one device file with a zero access mask. It
does not perform any other operations on the file.

The ShowWindow(SW_SHOWMINIMIZED):overlapped test shows that the
message should not be sent in general. This additional test shows that
we should still send the message if a menu is active.

Report the line number where the test failed to wait for the child so
one can identify which child process did not behave as expected.
Also wait_child_process() is meant for the general case so report
all non-crash error cases as test failures so they are accounted for.
Omit the "winetest_" prefix to match the other Wine test functions and
so the underlying winetest_wait_child_process() function can be wrapped
with the usual line-capturing macros.

This fixes a deadlock in the Steel Series Engine installer, between the
"user_section" lock and the loader lock.
Currently user32 takes the "user_section" lock during THREAD_DETACH, i.e. while
the loader lock is held. However, it is also possible for a thread to take the
locks in the reverse order. The observed path is:
- register_builtin()
- LoadCursorA()
- get_display_bpp()
- get_display_dc()
- CreateDCW()
- GetDeviceCaps(DESKTOPHORZRES)
- GetSystemMetrics(SM_CXVIRTUALSCREEN)
- EnumDisplayMonitors()
- update_monitor_cache()
Since we now rely on setupapi for fundamental tasks such as determining screen
size, it doesn't make much sense to delay-load it.

When explicitly requested by config, Wine will use null driver in the
same way as we allow using it for invisible winstations.
