+- openal input device added

- BWF muxer
- Flash Screen Video 2 decoder
-- ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
-- ffmpeg deprecated, added avconv, which is almost the same for now, except
+- lavfi input device added
++- added avconv, which is almost the same for now, except
+ for a few incompatible changes in the options, which will hopefully make them
+ easier to use. The changes are:
+ * -newvideo/-newaudio/-newsubtitle are gone, because they were redundant and
+ worked in a nonstandard way. -map is sufficient to add streams to output
+ files.
+ * -map now has slightly different and more powerful syntax.
+ + it's possible to specify stream type. E.g. -map 0:a:2 means 'third
+ audio stream'.
+ + omitting the stream index now maps all the streams of the given
+ type, not just the first. E.g. -map 0:s maps all the subtitle streams.
+ + colons (':') are used to separate file index/stream type/stream
+ index. Comma (',') is used to separate the sync stream. This is done
+ for consistency with other options.
+ + since -map can now match multiple streams, negative mappings were
+ introduced. Negative mappings disable some streams from an already
+ defined map. E.g. '-map 0 -map -0:a:1' means 'map everything except
+ for the second audio stream'.
+ * -vcodec/-acodec/-scodec are replaced by -c (or -codec), which
+ allows to precisely specify target stream(s) consistently with other
+ options. E.g. '-c:v libx264' sets the codec for all video streams,
+ '-c:a:0 libvorbis' sets the codec for the first audio stream and '-c
+ copy' copies all the streams.
+ * It is now possible to precisely specify which stream should an AVOption
+ apply to. See the manual for detailed explanation.
+ * -map_chapters now takes only an input file index and applies to the next
+ output file. This is consistent with how all the other options work.
+ * -map_metadata now takes only an input metadata specifier and applies to
+ the next output file. Output metadata specifier is now part of the option
+ name, similarly to the AVOptions/map/codec feature above.
+ * Presets in avconv are disabled, because only libx264 used them and
+ presets for libx264 can now be specified using a private option
+ '-preset <presetname>'.
