08a1b4d6b1 Add a DormantTimeoutEnabled to disable dormant mode entirely 
(If you need to do this in an older version you can just set
DormantClientTimeout to something huge.)

Closes #40228.

9ca2394d6b channel: Fix use after free in channel_do_open_actions() 
Fortunately, our tor_free() is setting the variable to NULL after so we were
in a situation where NULL was always used instead of the transport name.

This first appeared in 894ff2dc84 and results in
basically no bridge with a transport being able to use DoS defenses.

Fixes #40345

cd0e5a942e Terminate rep_hist_get_overload_stats_lines() with an NL. 
We use it in router.c, where chunks are joined with "", not with
NL... so leaving off the terminating NL will lead to an unparseable
extrainfo.

Found by toralf. Bug not in any released Tor.

6de09642f0 warn and reject reentering streams at client too 
Clients now check whether their streams are attempting to re-enter
the Tor network (i.e. to send Tor traffic over Tor), and they close
them preemptively if they think exit relays will refuse them.

See bug 2667 for details. Resolves ticket 40271.

890ae4fb1a Fix detection of point to insert signatures on a pending consensus. 
We were looking for the first instance of "directory-signature "
when instead the correct behavior is to look for the first instance
of "directory-signature " at the start of a line.

Unfortunately, this can be exploited as to crash authorities while
they're voting.

Fixes #40316; bugfix on 0.2.2.4-alpha.  This is TROVE-2021-002,
also tracked as CVE-2021-28090.
