Subject: Move crypto files out of base, to a top level directory.

src/crypto is now an independent project that contains our
cryptographic primitives (except md5 and sha1).

This removes the base dependency from nss, openssl and sqlite.

BUG=76996
TEST=none
Review URL: http://codereview.chromium.org/6805019

git-svn-id: svn://svn.chromium.org/chrome/trunk/src@81611 0039d316-1c4b-4281-b951-d872f2087c98
