Søren Schmidt 69b770e238 iBCS2 emulator core files.
This is the main files for the iBCS2 emulator. It can be use
compiled into the kernel by using:

options		IBCS2
options 	COMPAT_IBCS2

or as a lkm module using:

options		COMPAT_IBCS2

and then loading it via the ibcs2 script in /usr/bin

REMEMBER: this code is still experimental ! NO WARRENTY !
