Add crypto info to stream_get_meta_data() result on encrypted streams

A "crypto" key is added to the output of stream_get_meta_data() calls
when invoked using a stream on which crypto is currently active. The
new key's associated array contains the following keys:

 - protocol (string e.g. TLSv1.2, TLSv1.1, etc)
 - cipher_name (string)
 - cipher_bits (int)
 - cipher_version (string)

If the TLS ALPN extension was used to successfully negotiate an
application protocol that protocol's identifier is stored in the
following key:

 - alpn_protocol

If no ALPN protocol was negotiated the "alpn_protocol" key is not
present in the crypto meta data array. More meta information
concerning the stream's active encryption state may be added in the
future.
