Cleanup

keep uniform syscall convention throughout the .S
memory management / heap with SBRK etc.
use mprotect and friends to move data back into bss segment to have a sane executable size

61de6e96d53fc91cd1a188972a4adb22d0f4921c fixes the issue of forth words being in a text segment - they can now again be in the BSS segment.

Still need to figure out how to use mprotect to properly set permissions for self modifying code.
