The name of circpad_machine_state_t was very confusing since it was conflicting
with circpad_state_t and circpad_circuit_state_t.
Right now here is the current meaning of these structs:
circpad_state_t -> A state of the state machine.
circpad_machine_runtime_t -> The current mutable runtime info of the state machine.
circpad_circuit_state_t -> Circuit conditions based on which we should apply a machine to the circuit
so that the relays that would be "excluded" from the bandwidth
file because of something failed can be included to diagnose what
failed, without still including these relays in the bandwidth
authorities vote.
Closes#29806.
This is something we should think about harder, but we probably want dormant
mode to be more powerful than padding in case a client has been inactive for a
day or so. After all, there are probably no circuits open at this point and
dormant mode will not allow the client to open more circuits.
Furthermore, padding should not block dormant mode from being activated, since
dormant mode relies on SocksPort activity, and circuit padding does not mess
with that.
The previous commit introduces these changes:
Stop warning about undefined behavior in the probability distribution
tests. Float division by zero may technically be undefined behaviour in
C, but it's well-defined in IEEE 754.
Partial backport of 29298.
Closes ticket 29527; bugfix on 0.4.0.1-alpha.
They are simply not used apart from assigning a pointer and asserting on the
pointer depending on the cell direction.
Closes#29196.

Allow connections to single onion services to remain idle without being
disconnected.
Relays acting as rendezvous points for single onion services were
mistakenly closing idle established rendezvous circuits after 60 seconds,
thinking that they are unused directory-fetching circuits that had served
their purpose.
Fixes bug 29665; bugfix on 0.2.1.26.
