Save the media encoding name in the transport_info_t structure rather
than in a global variable.  Allocate it with tvb_get_ephemeral_string()
so it's released after the packet is completely processed.  Do *NOT*
assume it's necessarily non-null in decode_sdp_fmtp(), as the code flow
doesn't guarantee that to be true.

proto_tree_add_string() now suffices for adding a particular SDP item -
strings are now displayed "safely", with escaping of non-printable
characters done.

Update a comment (we no longer have the Big Transfer Vector to allow
plugins to call dissector functions in Windows, we have those functions
in a DLL).
