vd_lavc: allow explicitly selecting vdpau hw decoders 

This allows using the vdpau decoders with -vd without having to use
the -hwdec switch (basically like in mplayer).

Note that this way of selecting the hardware decoder is still
deprecated. libavcodec went away from adding special decoder entries
for hardware decoding, and instead makes use of the "hwaccel"
architecture, where hardware decoders use the same decoder names as
the software decoders. The old vdpau special decoders will probably
be deprecated and removed in the future.
