Implement new-style OpenSSL BIO callbacks

This provides support for new-style BIO callbacks in
BIO_{read,write,gets,puts}() and a helper function to
work out whether it should call the new or the old
style callback. It also adds a few typedefs and minor
code cleanup as well as the BIO_{get,set}_callback_ex()
