7cb050bd7d Ensure CIRC_BW event is emitted immediately upon slow start exit.
This ensures sbws gets this information quickly, so it can begin measurement.

53ebe16b12 fix typos, remove wrong stanzas, update 0.4.6.10
we were missing the 0.4.6.10 changes in ReleaseNotes, and the
0.4.0.5 releasenotes mistakenly included some 0.4.0.x bugfixes.

a956b20c1d Add a delta parameter to Vegas.
This allows us to cap the queue use during steady state. In shadow, this
reduced instances of long circuit queues at relays.

8052d0c2c0 Increase RTT ratio used to detect monotime jumps/stalls.
In Shadow, we saw RTT jumps as high as 1000 naturally.

So let's set this to 5000, to give us some breathing room.

86f81abe30 Properly compute the number or recv cells from deliver_window
Without this conversion, there is an implict 1000-recv_cells, which causes
the mod to fail if it is not a factor of 1000.

0eaf0e8a31 hs: Republish onion descriptor on sendme_inc change
Republishing is necessary to ensure that clients connect using the correct
sendme_inc upon any change. Additionally, introduction points must be
re-chosen, so that cached descriptors with old values are not usable.

We do not expect to change sendme_inc, unless cell size or TLS record size
changes, so this should be rare.

b5439d6bd0 trunnel: Make hs/cell_common.trunnel generic
Move it to extension.trunnel instead so that extension ABI construction
can be used in other parts of tor than just HS cells.

Specifically, we'll use it in the ntorv3 data payload and make a
congestion control parameter extension using that binary structure.

Only rename. No code behavior changes.

dd938e58d3 protover: Add function to get the value of a single type
We can now query the protover subsystem to get the current value we
support for a specific protover type.

This will be useful for prop324 onion service part which puts in the
FlowCtrl value in the service descriptor.

No behavior change.

b2789ae72a Add hidden torrc option to always try CC negotiation.
This is for public network testing and for sbws. Should not otherwise be used,
hence it is an undocumented __option.

The option deliberately does not allow force-disabling congestion control, as
this is bad for queueing and fairness.
