Threads starting better threads should stay at top.

This wasn't correct, I think I must've added it because something else
should've been rescheduling.
Update tests.
Eat cycles in sceKernelReferThreadStatus().

Improves .hack//Link (demo)'s perf significantly, doesn't hurt anyone

Restore volume shift to 15
In TYPE_SAVE/TYPE_LOAD, show a confirmation.

AUTOSAVE/AUTOLOAD don't, SAVE/LOAD do.
Move some things around and simplify.
Default to saveName for AUTO LOAD/SAVE modes.

Maybe should for others, but at least these for sure.

Improve automatic save/load based on tests
Mix add and xor in the texcache for better results.
Reuse the fullhash when it triggers a reload.

Instead of hashing it again a few microseconds later...
Load the clut only using LOADCLUT, not every tex.

This is a small optimization, and should match PSP behavior better.
It also allows us to hash the clut and convert colors less often.
Don't invalidate textures based on the clutaddr.

The cluthash should be sufficient, and this is less to pass around.
Only apply the clut offset when using the clut.

This may fix games that use the clut offset having wrong colors.
