Using tor_free is wrong; event_free must be called for objects obtained from
event_new. Additionally, this slightly simplifies the code.
Also, add a static_assert to prevent further instances.
It came as a surprise that Serge, the bridge authority, omits the Running
flag for all bridges in its first 30 minutes after a restart:
https://bugs.torproject.org/tpo/anti-censorship/rdsys/102
The fix we're doing for now is to accept it as correct behavior in
Tor, and change all the supporting tools to be able to handle bridge
networkstatus docs that have no Running bridges.
I'm documenting it here inside Tor too so the next person might not
be so surprised.
This code was heavily reused from the previous DNS timeout work done in
ticket #40491 that was removed afterall from our code.

cat will always print "cat: test_network_log: Is a directory". change it to
head -n -0, which is arguably not the perfect format but is at least somewhat
useful.
We had 3 callsites setting up the circuit congestion control and so this
commit consolidates all 3 calls into 1 function.

Once the cpath is finalized, e2e encryption setup, transfer the ccontrol
from the rendezvous circuit to the cpath.
This allows the congestion control subsystem to properly function for
both upload and download side of onion services.

This applies only for relays. Previous commit adds two new consensus
parameters that dictate how libevent is configured with DNS resolution.
And so, with a new consensus, we now look at those values in case they
ever change.
Without this, Exit relay would have to HUP or restart to apply any new
Exit DNS consensus parameters.

Introduces two new consensus parameter:
exit_dns_timeout: Number of seconds before libevent should consider
the DNS request a timeout.
exit_dns_num_attempts: Number of attempts that libeven should retry a
previously failing query before calling it a timeout.
