fate: use do_md5sum instead of the md5 protocol for most md5 fate tests
The md5 protocol has no seek support, but some tests use seeks. This changes
the fate tests to actually create the output files and calculate the md5 on the
written files, which also makes the tests independent of the size of the output
buffers and output buffering in general.
A new md5pipe fate test method is also introduced to keep the old functionality
for tests where using a non-seekable output was intentional, and matroska md5
tests are changed to use that.

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.

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>.
