New cbfstool. Works without mmap or fork/exec and

supports fixed location files. Some parts are salvaged
from the pre-commit version (esp. stage and payload creation),
others are completely rewritten (eg. the main loop that handles
file addition)

Also adapt newconfig (we don't need cbfs/tools anymore) and fix
some minor issues in the cbfstool-README.
