Adds a new property to qtmux that sets a path to a file to write and update data about the moov atom (that is not writen till the end of the file). If the pipeline/app crashes during execution it might be possible to recover the movie using the qtmoovrecover element. qtmoovrecover is an element that is also a pipeline. It is not meant to be used with other elements (it has no pads). It is merely a tool/utilitary to recover unfinished qtmux files. Fixes #601576
