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.

89f5eeefb8 hs: Decode flow-control line
This puts the flow control version (unparsed) in the descriptor. The
client doesn't use it yet.

95639f35ae hs: Encode flow control value in the descriptor
This simply adds the "flow-control" line, as detailed in prop324, to the
descriptor. No decoding is done at this commit.

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.

763d72238d kist: Don't try to flush empty outbuf
It is possible that a scheduled channel ended up with 0 bytes in its
outbuf after the scheduling loop and having an outbuf table entry
indicating that we need to flush bytes on the wire after the loop.

This lead to attempt to write 0 bytes up to the TLS layer that would
prevent such action.

All in all, this fixes wasted CPU cycles on attempting to flush nothing.

Fixes #40548
