jp9000 5c5f63e8b8 Output version/commit to RTMP stream metadata
Might come in useful for debugging issues later on.

jp9000 1d2e5d50a4 Add FLV file output code
This doesn't add FLV file output to the user interface yet, but we'll
get around to that eventually.  This just adds an FLV output type.

Also, removed ftello/fseeko because off_t is a really annoying data
type, and I'd rather have a firm int64_t for large sizes, so I named it
to os_fseeki64 and os_ftelli64 instead, and changed the file size
function to return an int64_t.

jp9000 a4a52d1c87 Fix bug where packets weren't interleaving
Packets were not interleaving, thus new data was being sent out with
potentially non-monotonically increasing timestamps

jp9000 519c4f4118 Fix issue when using multiple video encoders
- Fix an issue that could occur when using more than one video encoder.
   Audio/video would not sync up correctly because they were expected to
   be paired with a particular encoder.  This simply adds a little
   helper variable to encoder packets that specifies the system time in
   microseconds.  We then use that system time to sync

 - Fix an issue with x264 with fractional FPS rates (29.97 and 59.94
   particularly) where it would create ridiculously large stream
   outputs.  The problem was that you shouldn't set the timebase_*
   variables in the x264 params manually, let x264 handle the default
   values for it and leave them at 0.

 - Make x264 use CFR output, because there's no reason to ever use VFR
   in this case.

jp9000 92522d1886 Implement RTMP module (still needs drop code)
- Implement the RTMP output module.  This time around, we just use a
   simple FLV muxer, then just write to the stream with RTMP_Write.
   Easy and effective.

 - Fix the FLV muxer, the muxer now outputs proper FLV packets.

 - Output API:
   * When using encoders, automatically interleave encoded packets
     before sending it to the output.

   * Pair encoders and have them automatically wait for the other to
     start to ensure sync.

   * Change 'obs_output_signal_start_fail' to 'obs_output_signal_stop'
     because it was a bit confusing, and doing this makes a lot more
     sense for outputs that need to stop suddenly (disconnections/etc).

 - Encoder API:
   * Remove some unnecessary encoder functions from the actual API and
     make them internal.  Most of the encoder functions are handled
     automatically by outputs anyway, so there's no real need to expose
     them and end up inadvertently confusing plugin writers.

   * Have audio encoders wait for the video encoder to get a frame, then
     start at the exact data point that the first video frame starts to
     ensure the most accrate sync of video/audio possible.

   * Add a required 'frame_size' callback for audio encoders that
     returns the expected number of frames desired to encode with.  This
     way, the libobs encoder API can handle the circular buffering
     internally automatically for the encoder modules, so encoder
     writers don't have to do it themselves.

 - Fix a few bugs in the serializer interface.  It was passing the wrong
   variable for the data in a few cases.

 - If a source has video, make obs_source_update defer the actual update
   callback until the tick function is called to prevent threading
   issues.

jp9000 4a652ec82d obs-output module: Fill out more functions
- Add start/stop code to obs-output module

 - Use a circular buffer for the buffered encoder packets instead of a
   dynamic array

 - Add pthreads.lib as a dependency to obs-output module on windows in
   visual studio project files

 - Fix an windows export bug for avc parsing functions on windows.
   Also, rename those functions to be more consistent with each other.

 - Make outputs use a single function for encoded data rather than
   multiple functions

 - Add the ability to make 'text' properties be passworded

jp9000 0cf9e0cfdd Add preliminary FLV/RTMP output (incomplete)
- obs-outputs module:  Add preliminary code to send out data, and add
   an FLV muxer.  This time we don't really need to build the packets
   ourselves, we can just use the FLV muxer and send it directly to
   RTMP_Write and it should automatically parse the entire stream for us
   without us having to do much manual code at all.  We'll see how it
   goes.

 - libobs:  Add AVC NAL packet parsing code

 - libobs/media-io:  Add quick helper functions for audio/video to get
   the width/height/fps/samplerate/etc rather than having to query the
   info structures each time.

 - libobs (obs-output.c):  Change 'connect' signal to 'start' and 'stop'
   signals.  'start' now specifies an error code rather than whether it
   simply failed, that way the client can actually know *why* a failure
   occurred.  Added those error codes to obs-defs.h.

 - libobs:  Add a few functions to duplicate/free encoder packets
