Merge remote-tracking branch 'qatar/master' 

* qatar/master: (22 commits)
  configure: add check for w32threads to enable it automatically
  rtmp: do not hardcode invoke numbers
  cinepack: return non-generic errors
  fate-lavf-ts: use -mpegts_transport_stream_id option.
  Add an APIchanges entry and a minor bump for avio changes.
  avio: Mark the old interrupt callback mechanism as deprecated
  avplay: Set the new interrupt callback
  avconv: Set new interrupt callbacks for all AVFormatContexts, use avio_open2() everywhere
  cinepak: remove redundant coordinate checks
  cinepak: check strip_size
  cinepak, simplify, use AV_RB24()
  cinepak: simplify, use FFMIN()
  cinepak: Fix division by zero, ask for sample if encoded_buf_size is 0
  applehttp: Fix seeking in streams not starting at DTS=0
  http: Don't use the normal http proxy mechanism for https
  tls: Handle connection via a http proxy
  http: Reorder two code blocks
  http: Add a new protocol for opening connections via http proxies
  http: Split out the non-chunked buffer reading part from http_read
  segafilm: add support for raw videos
  ...

@ -19,6 +19,16 @@ API changes, most recent first:
2011-10-20 - b35e9e1 - lavu 51.22.0
Add av_strtok() to avstring.h.
2011-11-13 - lavf 53.15.0
New interrupt callback API, allowing per-AVFormatContext/AVIOContext
interrupt callbacks.
6aa0b98 Add AVIOInterruptCB struct and the interrupt_callback field to
AVFormatContext.
1dee0ac Add avio_open2() with additional parameters. Those are
an interrupt callback and an options AVDictionary.
This will allow passing AVOptions to protocols after lavf
54.0.
2011-11-xx - xxxxxxx - lavu 51.16.0
Add av_timegm()
