e268a352af mjpegdec: parse RSTn to prevent skipping other data in mjpeg_decode_scan 
Check explicitly if enough bits are left to prevent an infinite loop
when the bitstream buffer is not followed by zero-padding.

Based on patches by Michael Niedermayer <michaelni@gmx.at>.

4bf3c8f226 mov: Don't stick the QuickTime field ordering atom in extradata. 
The 'fiel' atoms can be found in H.264 tracks clobbering the extradata.
MJPEG supports non field based extradata, and this data should be
preserved when copying.

2e3c56a29f Set maximum lowres value for the MJPEG decoder to 3.

DCT is used by (m)jpeg.

737eb5976f Merge libavcore into libavutil 
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

bf5f9b528b Sanitise get_bits macros, part 1 
Some of the macros in get_bits.h include a final semicolon,
some do not.  This removes these or adds do {} while(0) around
the macros as appropriate and adds semicolons where needed in
calling code.
