MINOR: mux-h2: make streams know if they need to send more data

Browse Source 
H2 streams do not even know if they are expected to send more data or
not, which is problematic when closing because we don't know if we're
closing too early or not. Let's start by adding a new stream flag
"H2_SF_MORE_HTX_DATA" to indicate this on the tx path.
