Often the Linux / MacOS graphics driver version is of no use for
finding a proper driver version to report to the D3D app. So this
patch adds some infrastructure for easy hardcoding of card specific
driver versions to report to the application. This helps applications
which make assumptions based on the driver version, like bug
workarounds.

dbghelp: Disable the S_PUB_FUNC_XXX msc symbols until we know what they do (the first guess is wrong anyway).

dbghelp: When sending back information about a global symbol, only demangle the class & field/method name.

dbghelp: Extended the internal enumeration information so that we know the underlying integral type.

As we don't support C++ for now, we just return FALSE for all cases.

comctl32: Don't get the background colour in ANIMATE_PaintFrame as this can be called inside a critical section.

This could therefore create a deadlock if the processing for 
WM_CTLCOLORSTATIC ends up sending certain messages to the animate control.

So move the retrieval of the background colour into the callers of 
ANIMATE_PaintFrame but outside of any critical section.

winex11: Use the gdi display when initializing the keyboard to avoid creating a second display connection.
