Move some tests into the test subdirectory.

Now testcrypt has _two_ header files, that's more files than I want at
the top level, so I decided to move it.

It has a good claim to live in either 'test' or 'crypto', but in the
end I decided it wasn't quite specific enough to crypto (it already
also tests things in keygen and proxy), and also, the Python half of
the mechanism already lives in 'test', so it can live alongside that.

Having done that, it seemed silly to leave testsc and testzlib at the
top level: those have 'test' in the names as well, so they can go in
the test subdir as well.

While I'm renaming, also renamed testcrypt.h to testcrypt-func.h to
distinguish it from the new testcrypt-enum.h.

test/testcrypt-enum.h
