Add PKCS12_create.
PyOpenSSL calls this function these days. Tested by roundtripping with
ourselves and also manually confirming our output interoperates with
OpenSSL. (For anyone repeating this experiment, the OpenSSL
command-line tool has a bug and does not correctly output friendlyName
attributes with non-ASCII characters. I'll send them a PR to fix this
shortly.)
Between this and the UTF-8 logic earlier, the theme of this patch series
seems to be "implement in C something I last implemented in
JavaScript"...
