Added in more conditional checks for older versions of FFmpeg, so libopenshot will compile on more platforms.

Updated the FFmpegWriter to use compiler #IF commands to be compatible with older and newer versions of FFmpeg. This is still a work in progress, but many of the newer commands are now being protected.

Added in openMP code to improve performance on the timeline layer merging, which is very CPU intensive.

The timeline classes are finally working correctly, and have the following features:
...
1) Layers (unlimited # of layers)
2) IN, OUT, and Position (time)
3) X, Y offset
4) Alpha
5) Rotation
6) Transparency + compositing + overlays

Changed audio and video PTS to start at 0, and it fixed the final issues I have had with generating valid videos in multiple codecs.

Added code to flush the encoders, and also write the final frame's audio samples

Replaced avcodec_encode_audio with avcodec_encode_audio2, and completely redid the way PTS values are calculated and set. Another nice improvement!

Yet another huge refactor, to use shared_ptr objects instead of actual pointers, due to the difficulties in managing the lifecycle of pointers between the timeline, clip, and readers. Seems to work great, and solves all sorts of bugs. =)

Another huge refactor and lots of big fixes! Time mapping now works... mostly. The jumpy / glitchy images have been solved by copying the AVFrame into an AVPicture, which does not get clobbered on the next decode.
...
Also, added a new frame number overaly (in the top, left part of the image), and a new AddColor() method, to change the size and color of the frame's image...
Padded the end of the FFmpegWriter / WriteTrailer() method, to avoid having a codec ignore the last many frames.

Enabled multi-threading decoding and encoding with libavcodec, setting the thread_count property. This make a huge improvement in CPU performance, for codecs that support this property.

Fixed a big regression where the "omp" tag was not correct. Also, restructured the encoder to be much faster, and changed "omp master" to "omp single".

Added pool of software image scalers to the FFmpegWriter / encoder, and removed OMP critical section. Also, refactored some audio and video codecs, and changed "resize" to "scale" for speed improvements.

Fixed a huge bug where the FFmpegWriter was not scaling colors to 8 bit, and that would crash on certain colors being used in an image. Also, added a new, experimental waveform visualization to the encoder.

Fixed many bugs on the multi-threaded FFmpegWriter. Added audio multi-threading, and it mostly works... with a few bugs remaining.

Huge refactor, switched almost all methods to using pointers for Frames, and moved some key method calls outside the critical OMP sections. Also, refactored the sws scaler, to create a pool of 32 scalers, and give each thread it's own scaler. This refactor resulted in a 40%+ increase in speed on the FFmpegReader class.
...
I also added a cmake build flag for the google perftools library, to assist on profiling performance issues.
