Using the decode interrupt feature of ffmpeg may cause crashes by
accessing previously freed pointers in matroska_read_close.

To prevent this reset nb_elem to zero after freeing the elements,
because ffmpeg normally tests for nb_elem.

The delta escape (2) is supposed to work the same in 4-bit RLE as in
8-bit RLE.  This is documented in the MSDN Bitmap Compression page:
https://msdn.microsoft.com/en-us/library/windows/desktop/dd183383(v=vs.85).aspx

The unchecked modification of line is safe, since the loop condition
(line >= 0) will check it before any pixel data is written.

Fixes ticket #5153 (output now matches ImageMagick for the provided sample).

This prevents writing past bounds.

Fixes null pointer dereference

Testcase is simply a ffmpeg instance sending a stream to ffserver while another ffmpeg reads from it

This reverts commit 6f0a1710.

Since this is a C11 feature, it requires -std=c11.

Not actually used for anything yet, that will be added in the following
commits.

This merges libav commit 13f5d2bf.
