 `jabber_parse_close_stream` causes a connection to Prosody to fail when
 trying to upgrade to TLS.

 }}}

 The only difference between this and ejabberd and google talk and openfire
 is that prosody sends `<proceed></proceed>`, though that should still
 work.

 Changing the `xmlParseChunk` in `jabber_parser_close_stream` to send
 `</stream>` "fixes" it.

 I suspect a libxml2 bug, but need to write a test case outside of pidgin
 to test it.
