Merge remote-tracking branch 'qatar/master'
* qatar/master: (23 commits) build: cosmetics: Reorder some lists in a more logical fashion x86: pngdsp: Fix assembly for OS/2 fate: add test for RTjpeg in nuv with frameheader rtmp: send check_bw as notification g723_1: clip argument for 15-bit version of normalize_bits() g723_1: use all LPC vectors in formant postfilter id3v2: Support v2.2 PIC avplay: fix build with lavfi disabled. avconv: split configuring filter configuration to a separate file. avconv: split option parsing into a separate file. mpc8: do not leave padding after last frame in buffer for the next decode call mpegaudioenc: list supported channel layouts. mpegaudiodec: don't print an error on > 1 frame in a packet. api-example: update to new audio encoding API. configure: add --enable/disable-random option doc: cygwin: Update list of FATE package requirements build: Remove all installed headers and header directories on uninstall build: change checkheaders to use regular build rules rtmp: Add a new option 'rtmp_subscribe' rtmp: Add support for subscribing live streams ...
