crypto: split crypto into two implementations

On implementation for openssl_1_0_2e and one for openssl_1_1_0f. This is
bascally copying the existing impl and updating to compile when linking
to a shared-openssl.

Building for OpenSSL 1.1.0f:

./configure --debug --shared-openssl
--shared-openssl-libpath=/Users/danielbevenius/work/security/build_1_1_0f/lib
--shared-openssl-includes=/Users/danielbevenius/work/security/build_1_1_0f/include
--crypto-version=openssl_1_1_0f && make -j8
