FS#12975 - Wrong display of some .jpg-files

Hi developers,

recently I noticed Rockbox displaying some (not all) .jpg-files too bright and shifted/wrapped around (can’t describe it better so excuse my bad English first, please).
This happened with daily build 532b814-140418 but is present in Release 3.13 too. Attached are two examples consisting of .bmp-files (which render OK), the .jpg-files (rendering bad, same size and colors) and some Screendumps illustrating the problem. This Bug (if one) may affect other SanDisk players (Sansa Fuze, e.g.).

Greetings, …

Duplicate of  FS#12981  - JPEGs and album art with black backdrops don't display correctly.

The problem in both cases is triggered by the entropy data starting with FF 00. Because the FF looks like the start of a marker, process_markers() sets p_jpeg→p_entropy_data to point to the 00 when it should point to FF for correct decoding.
