			* qatar/master: (23 commits) x86inc: use sse versions of common macros instead of sse2 when applicable doc/APIchanges: add missing dates and hashes lavf: don't return from void av_update_cur_dts() Changelog: add more entries. Changelog: update ffmpeg/avconv incompatibility list. avconv: remove some redundant temporary variables. avconv: fix broken indentation avconv: move copy_initial_nonkeyframes to the options context. avconv: use file:stream instead of file.stream in log messages. doc/avconv: elaborate on basic functionality. doc/avconv: -sample_fmts, not -help sample_fmts prints the sample formats openssl: Only use CRYPTO_set_id_callback on OpenSSL < 1.0.0 Call avformat_network_init/deinit in the programs Remove leftover includes of strings.h avutil: Don't allow using strcasecmp/strncasecmp Replace all usage of strcasecmp/strncasecmp avstring: Add locale independent implementations of strcasecmp/strncasecmp avstring: Add locale independent implementations of toupper/tolower cosmetics: insert some spaces in explicit enum value assignments move 8SVX audio codecs to the audio codec list part on the next bump ...
