This is done in order to improve readability. No functional change is
intended with this commit at all; in particular, the unsafe read
functions are used throughout as h264_extradata_to_annexb already
performs its own checks. (These checks will nevertheless be improved
in further commits.)

bytestream2_get_bytes_left returns an unsigned int; as a result,
it returns big positive numbers if an overread already happened,
making it unsuitable for scenarios where one wants to allow this
in a controlled way (because the buffer is actually padded so that
no segfaults can happen). So change it to return an ordinary int.
Also, bytestream2_get_bytes_left_p has been modified in the same way.

The second ; in a double ;; is actually a null statement. It triggers
the typical declaration-after-statement compiler-warnings if it occurs
in the middle of several declarations (like here).

Currently width_align and height_align are zero when encoding with mjpeg_qsv,

Fixes "passing argument 2 of ‘strtoul’ from incompatible pointer
type [-Wincompatible-pointer-types]" ("expected ‘char ** restrict’ but
argument is of type ‘const char **’") for GCC and "passing 'const char
**' to parameter of type 'char **' discards qualifiers in nested pointer
types [-Wincompatible-pointer-types-discards-qualifiers]" for Clang.
The cast itself is safe; it is only needed because strtoul itself is not
const-correct.
