Thus, it may decode the slices in parallel to gain speed.

calls decode_rbsp_trailing() and therefore bit_length might get negative.
Although the remaining code is able to handle a negative bit_length, avoid
the calculation at all by setting bit_length to 0 for dst_length == 0.

Consider the following byte sequence
00 00 01 0a 00 00 00 01 09 ...
^ ^
A B
decode_nal() determines dst_length to be 1 (i. e. the byte between label
A and B above). However, this byte is a trailing zero byte as the spec
says the the current NAL unit is terminated by a byte sequence 00 00 00.
The current code used a loop to decrement dst_length accordingly. But the
loop doesn't start as the loop condition checks for dst_length > 1, which
should read dst_length > 0.

i.e. the four bytes 00 00 01 0a.
When decode_nal() decodes the end of sequence NAL unit, it returns with
dst_length == 0. The original code leads to a return -1 which discards
the current properly decoded frame.
