90a824a849 flowcontrol: fix start of the flow-control auto-tuning period (#4730) 
The period should start when the first frame is received, not when the data is
first read. This makes a difference when the first STREAM frame is received
out of order.

b8ea5c7981 simplify generation of STREAM_DATA_BLOCKED frames (#4608) 
The stream always gets blocked at the current write offset. There's no
need to return this offset from the flow controller.

42f04d4e02 refactor frame packing to logic to not access the streams map (#4596) 
* avoid accessing the streams map when packing stream data

* avoid accessing the streams map when packing flow control frames

* remove streamGetter interface

394aa5640d flowcontrol: make it possible to call Abandon multiple times (#4459) 
Abandon is called when a RESET_STREAM frame is received, and marks the
bytes between the highest read position and the final offset as
consumed. Making it possible to call Abandon multiple times makes using
this API a bit easier, since the stream doesn't need to track if it
already called it.

741dc28d74 move the RTTStats to the utils package 
The RTTStats are used by the logging package. In order to instrument the
congestion package, the RTTStats can't be part of that package any more
(to avoid an import loop).

bfbf0bca48 always queue window updates when data is being read 
There's no need to have a separate call in the flow controller interface
for this.

08160ab18f queue connection-level window updates from the flow controller directly 
It is not sufficient to check for connection-level window updates every
time a packet is sent. When a connection-level window update needs to be
sent, we need to make sure that it gets sent immediately (i.e. call
scheduleSending() in the session).

bfdeeae70c remove flow control mutexes for the sending data 
Receiving MAX_{STREAM}_DATA frames and sending data is all done
sequentially, so we don't need a mutex there.

f51cfe9fe3 don't send a window update after the final offset was received 
Receiving a final offset means the peer is done sending on that stream,
and there's no need to grant additional flow control credit.

636bf4578c error when receiving stream data with a larger offset than the final offset 
This could happen when a peer send a STREAM frame with the Fin bit set,
and then sends STREAM frames with a higher offset.
