Mint APE Loader v1.3

This version has better error messages and safety checks. It supports
loading static position-independent executables. It correctly handles
more kinds of weird ELF program header layouts. A force flag has been
added to avoid system execve(). Finally the longstanding misalignment
with our ELF PT_NOTE section has been addressed.
