We actually discovered a bug while combining the two functions with
FifoRecordAnalzyer's vertex array loading code. If per-vertex
postion or texture matrices were enabled and vertex arrays in use
then the wrong data would be used to calculate the minimum/maxmium
indices, which would result in either too much or too little vertex
data being included in the dff.
So this commit also increments the dff version number, so we can
identify old broken dffs later.
Texture updates have been moved into TextureCache, while
TMEM updates where moved into bpmem. Code for handling
efb2ram updates was added to TextureCache.
There was a bug for preloaded RGBA8 textures, it only copied
half the texture. The TODO was wrong too.
