qtmux: optionally create fragmented file
In this mode, an initial empty moov (containing only stream metadata) is written,
followed by fragments containing actual data (along with required metadata).
New fragments are started either at keyframe (if such are sparse) or when
property configured duration exceeded.
Based on patch by Marc-André Lureau <mlureau@flumotion.com>
Fixes #632911.
