[LTP] [PATCH 0/6] ltp: AF_ALG test helpers and a few regression tests

This series adds helper functions for testing AF_ALG (the userspace
interface to algorithms in the Linux kernel's crypto API) to the
Linux Test Project.  It then adds a few sample regression tests.

I've had these patches sitting around for a while with the goal of also
writing some "real" tests that test for more than these specific bugs,
but haven't gotten around to it yet.  And I now consider further
improving the in-kernel crypto self-tests to be a higher priority.  But
I figured I'd send this out as-is in case people are interested in
having this merged, e.g. maybe other people want to add AF_ALG tests to
LTP too and the 'tst_af_alg' lib would be a good starting point.
