avformat/cache: remove ftruncate usage, its not always available
...
In case of errors the cache file will be slightly larger than needed,
this should have no practical relevance though
Should fix build on VS201*

vdpau: add helper for surface chroma type and size
...
Since the VDPAU pixel format does not distinguish between different
VDPAU video surface chroma types, we need another way to pass this
data to the application.
Originally VDPAU in libavcodec only supported decoding to 8-bits YUV
with 4:2:0 chroma sampling. Correspondingly, applications assumed that
libavcodec expected VDP_CHROMA_TYPE_420 video surfaces for output.
However some of the new HEVC profiles proposed for addition to VDPAU
would require different depth and/or sampling:
http://lists.freedesktop.org/archives/vdpau/2014-July/000167.html
...as would lossless AVC profiles:
http://lists.freedesktop.org/archives/vdpau/2014-November/000241.html
To preserve backward binary compatibility with existing applications,
a new av_vdpau_bind_context() flag is introduced in a further change.
