[MPlayer-dev-eng] Patch: virtualdub plugin

[Alex Beregszaszi]

Hi,

I'm using C++ filters from pure C code, the configuring is working too,
but one main problem is with the VBitmap structure, it's inlined
functions are very annoying to emulate from C. Also if we finish the
VBitmap emulation, it's ready to work.

the latter is the changed one.
