Tested working by myself

Fixes needed when using newest revision variant of mcman and padman.

Make hook simpler due to sio2man using a single semaphore
Unhook intrman and loadcore when hooks no longer needed
Add API for interrupt handler
For loadcore and intrman hooks, only proceed when inner function succeeds

A major breaking change is that it now relies on the sio2man module from ps2sdk, which is smaller than the original SCE module and supports all known interfaces from 1.1 to 2.7.

FYI the mmceman driver was merged with this that @uyjulian PRd here:
Changes to mmceman for ps2sdk sio2man client updates

Hope its not breaking anything because then as it stands does this mean that newer mmce drivers will not work until this is merged? Trying to update wLE for the new mmce drivers as rename and set card+channel was integrated which I want in wLE R3Z.

I hope to test soon since wLE R3Z allows both mmce and mx4sio in it (gated between IOP reboot) as both driver sets loaded together causes issues.
