FFmpeg 3 & 4 support, Travis CI support, OpenMP schedule change ( #160 )
...
* FFmpeg4 support. Compile warnings fixes. Credit goes to many people, including ferdnyc, peterM, and other awesome folks!
* Adding environment checking to enable/disable omp taskwait after each video/audio frame is processed. This is experimental for some users with crashes.
* Moving `omp taskwait` to after the ProcessVideoPacket() method, since that is the only place it is useful.
* Fixing crashes on missing Clip source file, and changing FFmpeg scaling algorthm from SWS_BILINEAR to SWS_LANCZOS (for higher quality scaling)
* Update FindFFmpeg.cmake module, and updating build script. Also enabling debug builds.
* Updating experimental travis build script
* Fixed unit test for newer version of FFmpeg (audio resampling)
* Experimental travis multiple jobs
* Adding OMP schedule hint (thanks PeterM), which prevents crashes in some circumstances.

Adding new audio mixing enum, to allow for no automatic audio mixing, average mixing (where all overlapping clips average to 100% audio), or reduce mixing (where clips overlapping clips are all reduced by a constant value to reduce popping). ( #131 )

Adding metadata from format, audio stream, and video streams to ReaderBase.info, which in some cases includes the 'rotate' metadata added by certain cameras, and audio metadata like title, album, artist, copyright, dates, etc... Auto-Rotates any Clip with Reader metadata 'rotate' attribute.

Big update! Updating all "long int" frame number types to int64_t, so all 3 OSes will produce the same depth and precision on frame numbers. Also removing variable bitrate support temporarily, since it causes more problems than it solves.

Migrating tr1 to std, adding C++11 support to build scripts, fixing crash in FFmpegReader (caused by shared_ptr, buffer, and last_video_frame corruption). Much improved stability with this change. Thanks to Craig and Peter for the help!

Adding additional locks when adding/changing audio data. Reducing FrameMapper to a single frame at a time (increase seek speed and decrease crashes). Fixing crash on Time keyframes where it would sometimes calculate an invalid frame number.

Removing nested OMP processing from FrameMapper. Adding lock inside time mapping (to prevent crashes when speeding up/slowing down clips). Adding omp critial lock to Frame GetAudioChannelsCount() and GetAudioSamplesCount() methods.

Big improvement with handling invalid video and audio timestamps, defaulting to more sane values (when huge crazy timestamps are detected). Also fixing a bug when disabling video/audio tracks on FrameMappers. Also adding additional bail-out code when stuck searching for a video/audio packet that probably doesn't exist. Added improved "checked" handling, and once 1 frame is detected as invalid, clean out any other invalid ones as well.

Adding frame number display options to a clip, which can be super useful when debugging issues. Options include: None, Clip, Timeline, or Both. Also improving missing frame detection, to have less false positives (i.e. flickering 1st frame)

Removing transform handles, since I will instead implement that in Python rather this library. Also, refactoring a bit of the clip transforms, to keep the rotation center correct.

Huge refactor of keyframe point handles (bezier quadratic curves) to use CSS-style syntax. Basically, the left and right handles of a point now use percentages, such as 0.0, 1.0, 0.5, 1.0 (between 0 and 1), and become real coordinates based on the value differences between points (in real time). Also simplified the JSON property creation. Also, many unit tests have been updated, because they were actually generating the incorrect values from before... although only slightly in most cases. Now they have correct values from the default bezier handles.

Fixing crash when FrameMapper sometimes returns a blank Frame objects. Not sure why that is possible, but now it fails gracefully. Also, extending the cache clearing code on timeline +/- 1 more frame, to be sure we clear frames that have changed.

Improved image caching logic, to better estimate max image sizes possible, based on clip scale and keyframe settings... so we are always dealing with the smallest possible frame sizes for performance (without losing quality)

Added a new optimized constructor to some readers (FFmpegReader, QtImageReader, ImageReader) to not Open() in the constructor, which dramatically speeds up creating hundreds of Readers (i.e. when opening a project). This is really only useful when inflating the reader with Json right after you instantiate it...

Adding transform selection handles to a clip, which doesn't have much of a purpose yet, but it renders the rectangle handles for a clip (will soon be tied into the UI). Finally implemented shearing as a basic clip transform, which can be keyframed and animated. Refactored the timeline code where we do matrix transformations (QTransform), to simplify it.

Added SetMaxSize for image optimizations in QImageReader and FFmpegReader, which lets the timeline pass down the max size to all clips and readers, so they can optionally optimize the size of images (especially useful for optimizing preview performance). Removed convoluted image scaling code in FFmpegReader, and replaced with simpler version. Also, fixed a few regressions from the new Caching code, primarily a crash when reaching the end of the last clip on the timeline.
