more asm symbol prefixing: variables with p8v_, subroutines with p8s_ etc
...
labels with p8l_ . All this to avoid symbol clashes in the generated assembly code.
Everything got its own distinguishing prefix so we're done with it once and for all and have only 1 breaking change moment.

breaking change: sys.set_irq() and sys.set_rasterirq() no longer have useKernal parameter! The irq handler routine must return a boolean instead in the A register.
...
When it returns true it means run the system IRQ handler afterwards. When it returns false, the system handler is NOT ran afterwards.

c64: added a couple of routines that calculate the correct memory locations for video ram and sprite pointers etc. based on current VIC-II memory setup.
...
the examples with sprites, now use it.
