Apparently, some build environments require dxva.h even for dxva2,
while others lack this header entirely. Including it conditionally

When there is just 1 byte remanining in the buffer, nothing will be read
and the loop will continue forever. Check that there are at least 8
bytes, which are always read at the beginning.

The check `src > dst' in the form `&c->out[-back] > c->out' invokes
pointer overflow, which is undefined behavior in C.
Remove the check. Also replace `&c->out[-back] < c->out_start' with
a safe form `c->out - c->out_start < back' to avoid overflow.

The values compared here can be more than INT64_MAX apart. Since the
difference is always positive, converting to uint64_t before subtracting
gives the correct result without overflows.

blocksize to make sure the comparison logic is correct and report
