6bc079c7b7 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.

08ac459a41 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.
