From cf05aea092fad448c2f4a8e8b66159237096ba8e Mon Sep 17 00:00:00 2001

Subject: Update and consolidate the test framework.

The tests previously had used 4 to 6 different schemes internally (the vec file
reader framework, Catch, the old InSiTo Boost.Test tests, the PK/BigInt tests
which escaped the rewrite in 1.11.7, plus a number of one-offs). Converge on a
design that works everywhere, and update all the things.

Fix also a few bugs found by the test changes: SHA-512-256 name incorrect,
OpenSSL RC4 name incorrect, signature of FFI function botan_pubkey_destroy
was wrong.
