1a38f6fa7d Properly remove terminated thread from ready queue. 
If we change the priority first, we'll remove from the wrong priority
level, oops.  Gotta change afterward.

Should improve Darkstalkers Chronicle: The Chaos Tower.

183b4cb45c Add a static method for creating PSPPointers. 
This is still kinda ugly, but the assignment thing was just too ugly, I
couldn't do it anymore.

e73d43c434 Correct sceKernelTlspl func names, etc. 
This is mostly pedantic but it's nice to have the right names.

7dedf54bc3 Always resched in thread queue rotation. 
It might be time to reschedule anyway, some games call this in a loop with
an empty queue.

May help Harukanaru Toki No Naka de Hachiyoushou (#4669.)

55500d4bb6 Reorder VFPU registers in memory so that we can flush and reload them in bulk more often. 
Doesn't actually do that yet, that's for the NEON branch.

26f5922174 Return the correct value for fcr0/fir. 
This is what the PSP actually returns, it's read only.

baa82e0a9d Keep syscalls the same in the interpreter. 
Rather than having different bugs.

d400b1a67b Keep track of the current thread obj. 
To reduce overhead/improve perf.  Actually, it used to be only the current
thread object, but now it's just a cache with accessors.

9ebaf7b68b Fill registers with 0xDEADBEEF after most syscalls. 
Some, like sceMpegRingbufferPut(), we don't, since... it's complicated.
But most we do, like a real PSP does.

f5e0d80ead Pass arguments to root threads same as regular. 
Before it would have issues or crash if the args were > 256 bytes.
Fixes Ys 1 & 2 Chronicles.

e06889069c Don't use the destructor to free thread stacks. 
If we do, kernelObjects.clear() will trash perfectly good memory on
loading a state.  I guess it also makes shutdown slower.

Fixes #4186.

a7ec139b5a Savestate the exit callback, reporting. 
Seems like LoadExecForUser_362A956B() uses it, so we need to save it.
I have no confidence that function works correctly, so let's report it.

a3637a1cad Set the low mystery bits of the thread attr. 
Tests on PSP show this, and I can't find a way to not have them set.
But I don't really know what they mean.

Anyway, since you can refer the status, you can see them, may improve
compatibility.

0af3c50924 Eat cycles after creating a thread.

64b75ed3ff Decentralize callback registration. 
Callbacks are always tied to THEIR thread, and the registration was all
based on the current thread which is just not the right way.

94e88943d8 Keep a single list of pending callbacks. 
Doing it per type only meant that we'd incorrectly call a callback twice
if it was notified by e.g. scePowerRegisterCallback() and
sceKernelNotifyThread(), which isn't what's supposed to happen.
