Add a readme giving the date / revision of these sources.
show clear error message instead of 987 when too many setjmp calls
not using Changelong anymore
big function finder tool
use invoke when doing a setjmp-guarding call via a function pointer
make sure to coerce arguments to invoke due to setjmp
Clean up libc / libcxx build infrastructure.

This creates a couple of additional methods to reduce copy/paste
and make things a bit easier to follow.
