de70eebc65 Start on a command-parsing tool for controller commands.
There _is_ an underlying logic to these commands, but it isn't
wholly uniform, given years of tweaks and changes.  Fortunately I
think there is a superset that will work.

This commit adds a parser for some of the most basic cases -- the
ones currently handled by getargs_helper() and some of the
object-taking ones.  Soon will come initial tests; then I'll start using
the parser.

After that, I'll expand the parser to handle the other cases that come
up in the controller protocol.

bdeaf7d4b2 Code to manage publish/subscribe setup via subsystem interface.
This commit has the necessary logic to run the publish/subscribe
system from the mainloop, and to initialize it on startup and tear
it down later.

Correctly report PT vs proxy during bootstrap
Previously, or_connection_t did not record whether or not the
connection uses a pluggable transport. Instead, it stored the
underlying proxy protocol of the pluggable transport in
proxy_type. This made bootstrap reporting treat pluggable transport
connections as plain proxy connections.

Store a separate bit indicating whether a pluggable transport is in
use, and decode this during bootstrap reporting.

Fixes bug 28925; bugfix on 0.4.0.1-alpha.

circpad: Rename circpad_machine_state_t to circpad_machine_runtime_t.
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

circpad: Don't pad if Tor is in dormant mode.
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.

aee65084b4 circ: Remove n_mux and p_mux members
They are simply not used apart from assigning a pointer and asserting on the
pointer depending on the cell direction.

a71999462b Fix test prob distr parameters that caused warnings.
They were causing the following warnings in circuitpadding/circuitpadding_sample_distribution:

     src/lib/math/prob_distr.c:1311:17: runtime error: division by zero
     SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior src/lib/math/prob_distr.c:1311:17 in
     src/lib/math/prob_distr.c:1219:49: runtime error: division by zero
     SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior src/lib/math/prob_distr.c:1219:49 in

because the distributions were called with erroneous parameters (e.g. geometric
distribution with p=0).

We now defined these test probability distributions with more realistic
parameters.

As far as the circuitpadding_sample_distribution() test is concerned, it
doesn't matter if the distributions return values outside of [0,10] since we
already restrict the values into that interval using min=0 and max=10 (and RTT
estimate is disabled).
