25f25a8767 Get rid of sort() and reverse() builtin functions.
Sort() had too many gotchas and reverse() is kinda redundant you can loop in decreasing order through an array too.

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.
