  [inets/httpc] Add proper code change code
  [inets/httpc] Add test case
  [inets] Add proper release notes for OTP-9847
  [inets/httpc] Fix the selection of session for keep-alive mode When selecting a session, the "state" of the session (specifically if the server has responded) was not taken into account. Attempting to fix this, a "state" field (actually available) has been added to the session record.
