videos_ only learns about the CSC output, so the texture we actually draw is
just an ordinary 512x512 8888 texture whose contents happen to be different
every frame: hash, miss, throw it in the secondary cache, rebuild, forever.
So track the copy. NotifyVideoCopy marks the destination as video when the
source is, and the copy funnels call it: sceDmacMemcpy, sceKernelMemcpy, and
the four replaced memcpy/memmove variants. It sits outside their "is either
side VRAM" gate, since a RAM-to-RAM copy of a frame is still a frame.
Being a video texture also gets it forced linear filtering and keeps it out of
texture upscaling, which is what you want for a video either way.

From another pass over ge.prx against our code, each checked on a PSP with
gpu/ge/callbackstate except the last:
- A list's context is restored after its finish callback, which sees the
state the list left. We restored at the FINISH, before it. Now that nothing
runs until InterruptEnd(), that's where it happens.
- sceGeSaveContext/RestoreContext only fail while the GE is executing. It's
stopped during a finish callback and a SUSPEND signal callback, however
much is queued, so they work there. We said busy whenever a list existed.
- sceGeListDeQueue emptying the queue doesn't turn completed lists into
nothing, only sceGeDrawSync does. CheckDrawSync() is gone.
- The "break in progress" flag that makes sceGeContinue only requeue the
list is cleared by an interrupt that follows the break at once, so it's
only seen from a callback or with interrupts off. Ours lasted until the
next GE interrupt of any kind.
- sceKernelLoadExec restarts the GE driver, which begins by zeroing every
register and matrix. Reinitialize() now does too, so a program started that
way finds the same GE as one booted directly, rather than its launcher's.
Not testable on hardware: nothing after the restart can report back.
