SPDY: better name for frame entries counter.

Browse Source 
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.
