SPDY: better name for frame entries counter. The "headers" is not a good term, since it is used not only to count name/value pairs in the HEADERS block but to count SETTINGS entries too. Moreover, one name/value pair in HEADERS can contain multiple http headers with the same name. No functional changes.
