Subject: [PATCH 1/1] Add support for computing hashes using OpenSSL

It adds WITH_OPENSSL build option.

If it is ON, OpenSSL will be used instead of internal implementation

of computing hashes (MD5, SHA1, SHA224, SHA256, SHA384, SHA512).

Rebase of https://github.com/openSUSE/libsolv/commit/9839a88e4fda23b46015170b201c98da7bcdd55e
