default_ref[] is unconditionally initialized in h264_initialise_ref_list()
(called from ff_h264_build_ref_list(), called from h264_slice_init()).

This fixes the following tsan warning when running fate-h264:

Use integer position instead of pointer for loop variable. Also only
skip header fields after header has been fully validated.

Avoid undefined behavior in skip_input() by checking that enough data is
available before incrementing input pointer.

Check return values of parse_key() and skip_input() and exit early with
error if there is not enough data.
