Updating references to frame number / position to long int, there were still quite a few old "int" declarations, which limits the length of frame number. Also, updated precision of KeyFrames to use double (instead of float) for higher precision, which fixed lots of issues with very long videos (since our FrameMapper used a KeyFrame object to create a map to new frames)

Fixing small bug with audio PTS detection, when seeking on really long video files (which would reset the last_frame to -1, and then detect a huge # of incorrect missing frames)

Fix AudioLocation::is_near function to handle a corner case where the two frames have different samples_per_frame, and sample_start is at the samples_per_frame limit.

Large refactor of detecting missing frames, to make it more accurate and dramatically improve performance for many videos.

Ensure Seek() waits for any outstanding video/audio frames to be processed in other threads before attempting a seek (and potentially crashing)

New cross platform exception handler for libopenshot! Logs basic stacktrace on segmentation fault. This will be a huge help in finding bugs and crashes.

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...

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.

Implementing a small memory bug fix with regards to AV_FREE_FRAME and audio_frame. Also adding in support for duration to be set by JSON, to support long videos from openshot-qt.

Fixing a crash on Windows by using a different overload of AddImage that doesn't do a memcpy. There is still a memory leak on the FFmpegWriter somewhere, which eventually starts to return NULL from av_malloc, and breaks on Windows (and probably other OSes too).

Big memory leak fixes in FFmpegReader and FrameMapper, and fixed logic in Frame Mapper with regards to special framerate conversions (24, 25, and 30)... which were causing some inadvertent audio drift.

Improved detection of missing audio frames, and missing video frames. Also improved logic for giving up on missing frames in general. Also removed some deadlocks related to Seeking (Close() and Open() were deadlocking). The end result is much improved compatability with reading video files.

Added 4 new clip keyframes (channel mapping, channel filter, has_video, and has_audio). These are a bit different though, as they are evaluated as boolean (-1 = ignored, 0 = disabled, 1 = enabled). Also fixed some issues with video playback (where it gets stuck in fast forward), and fixed some race conditions when opening FFmpegReader. Also added more debug output.

Moved AppendDebugMessage to ZmqLogger, and updated 100+ references to use this new function. Removed debug var from readers/writers, and moved it to ZmqLogger.Enable(true/false). This allows debug output from all classes and functions, without any duplicate code. Also added some additional debug output for video playback and audio readers.

Adding new dependency: libzmq (ZeroMQ). Adding a new debug logging class powered by sockets and ZeroMQ, to allow a threadsafe way to communicate debug messages to a client application (i.e. openshot-qt). Also, removing unneeded Sleep.h functions. There will be lots more code utilizing ZeroMQ soon.

When a seek fails, disable seeking with FFmpegReader. This fixes lots of issues with image sequences, but needs more testing to see if it causes issues with normal video files.
