* qatar/master: (29 commits) lavfi: reclassify showfiltfmts as a TESTPROG graph2dot: fix printf format specifier swscale: yuv2planeX 8bit >=sse2 functions need aligned stack on x86-32. vp8: loopfilter >=sse2 functions need aligned stack on x86-32. amr: remove shift out of the AMR_BIT() macro. dsputilenc: group yasm and inline asm function pointer assignment. mov: use forward declaration of a function instead of a table. Clarify Doxygen comment for FF_API_* #defines. configure: simplify get_version() Create version.h headers for libraries that lack them gitignore: Use full path instead of relative path to specify patterns mpegvideo: remove VLAs Add XTEA encryption support in libavutil Add Blowfish encryption support in libavutil eval: Add the isinf() function and tests for it flacdec: move lpc filter to flacdsp flacdec: split off channel decorrelation as flacdsp avplay: Add an option for not limiting the input buffer size FATE: add a test for WMA cover art. FATE: add a test for apetag cover art ...
