Ganesh Ajjanagadde 7179add427 avcodec/ac3enc: use long long after switch to 64 bit bitrate Commit `7404f3bdb` switched bitrate to 64 bits. This triggers -Wabsolute-value on clang, e.g http://fate.ffmpeg.org/log.cgi?time=20150917122742&log=compile&slot=x86_64-darwin-clang-3.7-O3. Therefore, usage of abs is changed to llabs, which is available on all of the platforms. Unfortunately, LLONG_MAX is not always available, so INT64_MAX is used instead.
