Port DirectShow backend to wince

dshow.h needs to be included before Qt headers as they include the
windows header with NOMINMAX macro set. DirectShow header needs min/max
macro definition to compile. The min/max macro then conflicts with
QDateTime header, hence needs to be undefined again for some occasions.

Windows Embedded Compact then defines INTERFACE as macro, which conflicts.

Windows Embedded Compact does not support audio end point selection.
Feature has been disabled for this platform.

Windows Embedded Compact does not support setting meta data, control has
been disabled.

Windows Embedded Compact does not support VMR, feature was disabled.

Direct Show renders always top to buttom.
