Add MinSFI loader

This patch implements a memory initialization routine as part of MinSFI's
trusted runtime. The code reads the manifest of the sandbox it was compiled
against, mmaps a sufficiently large memory region and jumps into the
sandbox's entry function. There is no support for multiple simultaneously 
active sandboxes or multithreading.
