I put 3 files on

1. libssp.tar.gz: A BSD licensed re-implementation of GNU's libssp. Questions:
	- Do we put this as a separate library or we fold it in libc?
	- Why do we need to install libssp-nonshared.a?
	- Shouldn't the _FORTIFY_SOURCE stuff and -I/usr/include/ssp
	  happen automatically?

2. libssp-regress.tar.gz: Regression tests for the above. Questions:
	- Is it ok that some of the regression tests abort when they
	  are successful?

3. libssp-kern.diff: These are non-working diffs to eliminate alloca
	and variable array allocations from the kernel. Issues:
	- malloc vs alloca performance
	- what to do when we cannot sleep
	- the constructor stuff will not work in the kernel; we should
	  call the initializer directly from main?
	- should we just compile the files that have variable stack
	  allocations with -Wno-stack-protector?
