some work about kernel module support

[tpunix]

https://github.com/tpunix/ppsspp/tree/kmod
This is my attempt to support kernel modules. It's not finished. The game(chinese translate) can load and run, but hang at last.
The code can not be merged now... too many hacks inside it.

[tpunix]

https://github.com/tpunix/ppsspp/tree/libfont_support
another hacks: sceReg support. with this, the official libfont.prx can be load and run.

[tpunix]

This code is writen based an old ppsspp versions.

[hrydgard]

With some cleanup (like removing the asset files you added accidentally) both of these would be easy to merge with current PPSSPP.

Well, I'm not sure about the PSP_GetKernelMemoryBase() changes or some of the flags handling...

[tpunix]

I change the kernel address from 0x08000000 to 0x88000000. It is the real address used on psp.
There have a pending problem: Core/MIPS/x86/Jit.cpp use this address to do something. I dont know how to handle it.

@tpunix Have you changed to PSP Model to 1000 to test ?

Because you always return 0 in kuKernelGetModel

SysclibForKernel is done by @unknownbrackets but still not test
https://github.com/hrydgard/ppsspp/blob/master/Core/HLE/sceKernelInterrupt.cpp#L595

[unknownbrackets]

Well, the top bit is just set for kernel access. For the purposes of jit, and for many other purposes, we want it to stay 0x08000000 I think. We should just OR in the kernel bit as appropriate.

@hrydgard can we try to add support of missing kernel module before v0.9.9 ?
