Build environment: Enable SSL for Python on Linux
This involved getting SSL compiled from sources first, ensuring it is a static library placement independent code. Configuration is based on what Debian is using. CFlags required to have own configuration file, which i didn't find a better place that next to the corresponding CMake file. It is OpenSSL btw. It is set to Python via --with-openssl= configuration argument. This works fine in a clean chroot, but having libssl-dev installed might make Python to prefer system wide library, This was worked around by using libssl_pic.a name for the library and modifying setup.py. Would be cool to ensure system wide libraries are not a problem, but official release builder is safe against this, since it will catch possible non-static dependencies. There is also a new map file which shadows bunch of Python symbols. Without this Python's shared libraries might bring conflicting symbols to Blender namespace at runtime. Hopefully this doesn't break other platforms.
