8d1889c116 Revert initializing globalwrap state 
Leave globalwrap state as uninitialized, even if that causes a compile
warning as initializing breaks AVI dumping on Windows. All globalwraps
should have static storage duration anyway, and C++ can not have
uninitialized variables with static storage duration.

b642237e96 SNES: Actually make L=0 be full black 
Turns out there are three copies of LRGB->RGB routine (two 8-bit and one
16-bit). Merge the 8-bit ones and remove L+1 causing L=0 to be not fully
black. Fixes fade afterimages in Super Mario World.

fb28e30fcc Fix Lua register* callback list corruption 
Turns out nothing was setting the prev pointer on doubly linked list when
creating callback nodes, so Lua GC'ing any node from the middle corrupted
the list, leading to unregister* intermittently failing to actually
unregister the callback.

6fb4e1396d Lua: Delay freeing callback handles if executing 
If callback is executing, its callback handle must not be freed as freeing
it would trigger UAF. So if currently running callback is unregistered,
delay freeing the handle until the callback finishes running.

subframes, but does not deal with things like Super Game Boy.

f537f4943c Lua: Guard against Lua returning non-string error 
Turns out that if Lua throws e.g. a table as error, tostring (and
tolstring) returns NULL. And trying to print NULL into message stream
causes it to hang). Guard against tolstring returning NULL, and print
(null) instead of trying to print the NULL pointer.

4c9bb20270 Fix crash if mouse_x or mouse_y are hooked 
Turns out framebuffer draw recalibrates mouse_x and mouse_y, which then
calls into hook. Which is no-no, because framebuffer draw runs in GUI
thread, and hooks must run in game thread.
