VSE: Cache rewrite

This patch implements new cache system.
Aim is to give user more control over cache, so it can be maximally
utilized. This is done through sequencer timeline side panel
in category proxy & cache.
Cached images are also visualized in timeline, controled by
sequencer timeline view->cache menu

Functional changes:
 - NOT use IMB_moviecache API
 - refactor names of cached image types
 - each scene owns 1 sequencer cache
 - merge preprocess cache into per-sequencer cache
 - cache links images rendered per frame in order as they are created
 - add cache content visualization tool
 - add RNA properties to control the cache

More info can be found in design notes in blenkernel/intern/seqcache.c
and in https://developer.blender.org/D4443
