Peter Jones 1d39ada8cb Revert lots of Cryptlib updates.
OpenSSL changes quite a bit of the key validation, and most of the keys
I can find in the wild aren't marked as trusted by the new checker.

Intel noticed this too: https://github.com/vathpela/edk2/commit/f536d7c3ed
but instead of fixing the compatibility error, they switched their test
data to match the bug.

So that's pretty broken.

For now, I'm reverting OpenSSL 1.1.0e, because we need those certs in
the wild to work.

This reverts commit 513cbe2aea.
This reverts commit e9cc33d6f2.
This reverts commit 80d49f758e.
This reverts commit 9bc647e2b2.
This reverts commit ae75df6232.
This reverts commit e883479f35.
This reverts commit 97469449fd.
This reverts commit e39692647f.
This reverts commit 0f3dfc01e2.
This reverts commit 4da6ac8195.
This reverts commit d064bd7eef.
This reverts commit 9bc86cfd6f.
This reverts commit ab9a05a10f.
