bff7bec1d7 vf_deinterlace_vaapi: Add support for field rate output 
In order to work correctly with the i965 driver, this also fixes the
direction of forward/backward references - forward references are
intended to be those from the past to the current frame, not from the
current frame to the future.

0b1794a43e hwcontext: Make it easier to work with device types 
Adds functions to convert to/from strings and a function to iterate
over all supported device types.  Also adds a new invalid type
AV_HWDEVICE_TYPE_NONE, which acts as a sentinel value.

92bd089745 vaapi_encode: Discard output buffer if picture submission fails 
Previously this was leaking, though it actually hit an assert making
sure that the buffer had already been cleared when freeing the picture.

f2e4fb61af hwcontext_vaapi: Try to support the VDPAU wrapper 
The driver is somewhat bitrotten (not updated for years) but is still
usable for decoding with this change.  To support it, this adds a new
driver quirk to indicate no support at all for surface attributes.

Based on a patch by wm4 <nfxjfg@googlemail.com>.
