mjpegdec: consider chroma subsampling in size check

If the chroma components are subsampled, smaller buffers are allocated for them. In that case the maximal block_offset for the chroma components is not as large as for the luma component. This fixes out of bounds writes causing segmentation faults or memory corruption.

+   The FFmpeg Project proudly presents FFmpeg 2.5 "Bohr", 2.5 months after the
+   release of 2.4.

-   The most important thing in this release is the major version bump of the
-   libraries.  This means that this release is neither ABI-compatible nor
-   fully API-compatible. But on the other hand it is aligned with the Libav
-   11 release series, and will as a result probably end up being maintained for
-   a long time.
+   The most important new features are AVFoundation screen-grabbing support,
+   animated WebP decoding support, and Animated PNG support. In addition, many
+   exciting features for video streaming are also implemented, including MPEG-
+   DASH fragmenting muxer, HEVC RTP payload muxer, and UDP Lite support.

+The muxer supports writing attached pictures (APIC frames) to the ID3v2 header.
+The pictures are supplied to the muxer in form of a video stream with a single
+packet. There can be any number of those streams, each will correspond to a
+single APIC frame.  The stream metadata tags @var{title} and @var{comment} map
+to APIC @var{description} and @var{picture type} respectively. See
@url{http://id3.org/id3v2.4.0-frames} for allowed picture types.

 Note that the APIC frames must be written at the beginning, so the muxer will
 buffer the audio frames until it gets all the pictures. It is therefore advised
 to provide the pictures as soon as possible to avoid excessive buffering.

+@item
+A Xing/LAME frame right after the ID3v2 header (if present). It is enabled by
+default, but will be written only if the output is seekable. The
+@code{write_xing} private option can be used to disable it.  The frame contains
+various information that may be useful to the decoder, like the audio duration
+or encoder delay.
+
+@item
+A legacy ID3v1 tag at the end of the file (disabled by default). It may be
+enabled with the @code{write_id3v1} private option, but as its capabilities are
+very limited, its usage is not recommended.
