Many Updates

Bumps every http://openssl.org link to the correct https://openssl.org. Also corrects the remnants of OpenSSL 1.0.1c to 1.0.1h. Also corrects the OS X build instructions to have the correct link to Homebrew, the correct OpenSSL check & removes the dangerous force link instructions. With the patch provided by contrib/homebrew/makefile.osx.patch there is *no need* to force the OpenSSL build onto the wider system.
