The code below the comment does not at all relate to statistics,
and even if moved to the right place, the comment adds little
value.

Fixes null pointer dereference later, since if this function failed,
a positive return value was returned to the caller.

Manually load registers to avoid using 8 registers on x86_32 with
compilers that do not align the stack (e.g. MSVC).

Accept the buffer size in bytes and check for overflow before passing
the value in bits to init_get_bits.

Fix an undefined behaviour and make the function return a proper
error in case of overflow.

Freeing it in av_destruct_packet(), as is done currently, would mean
that we allow it to be allocated with other means. But that would make
av_packet_new_side_data() unsafe.

Side data is not expected to be large, so copying it if required
shouldn't be a problem.

Codec timebase is supposed to be set by decoders only.

v4l2_read_header() does no cleanup, so it can return directly, without
any need for goto.
