printf() optimization: Use syscall and mov r14 to rax rather than calling print and strlen -- r14 used to contain wrong length: mistakenly increased r14 (and performed checks) for printfNBuff

Minor optimizations in printf() (stop using rbx and r13, use smarter checks instead + pop r11 correctly (prevent stack corruption))

FIX: No longer allow exceeding printf buffer, instead print an error to stdout. Temporary fix
Later, if buffer is full, print current buffer and reset buffer so that there is no limit.
