* qatar/master: (31 commits) tiffenc: initialize forgotten avctx. avplay: free the active audio packet at exit. avplay: free rdft data used for spectrogram analysis. log.h: make AVClass a named struct fix ac3 encoder documentation vc1: more prettyprinting cosmetics vc1: prettyprint some tables vc1: K&R formatting cosmetics AVOptions: bump minor and add APIchanges entry. cmdutils/avtools: simplify show_help() by using av_opt_child_class_next() AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_* Remove all uses of deprecated AVOptions API. AVOptions: add av_opt_next, deprecate av_next_option. AVOptions: add functions for evaluating option strings. AVOptions: split get_number(). AVOptions: add av_opt_get*, deprecate av_get*. AVOptions: add av_opt_set*(). AVOptions: add new API for enumerating children. rv34: move inverse transform functions to DSP context flvenc: Write the right metadata entry count ...
