* Introduced a boolean parameter to parseAndFill() and parse(), that specifies whether to notify the application demand callback.
  This is necessary because reads may happen from any threads, and must not notify the application demand callback.
  Only when there is no data, and fill interest is set, then the application demand callback must be notified.
* Removed action field to avoid lambda allocation.
* Now the application is called directly from the parse() method.
* Reading -1 from the network drives the parser by calling again parse(), rather than the parser directly.
  This allows to have a central place to notify the response success event.

…ntent.

This avoids the rare case where the response arrives before the request thread has modified the request state, even if the request has been fully sent over the network, causing the request to be failed even if it should not.
