902a55f716 dxva2_hevc: re-write reference frame handling 
The old logic required an explicit clearing of the lists first and was
prone to overflow the DXVA2 struct in some circumstances.

5c720657c2 mov: always check avio_read return value 
If avio_read fails, the buffer can contain uninitialized data.

This fixes 'Conditional jump or move depends on uninitialised value(s)'
valgrind warnings, and addresses a few memleaks.

MSG_NOSIGNAL).
