489628a7e4 Bug 23101: Pre-build HS-specific circuits (instead of general). 
Prebuilt circs are 4 hops, since only server side HSDIR and intro circs
are 3 hops, and it is OK if those sometimes take longer to build.

97d9ba2380 Add a mostly disabled feature to debug restarting in-process 
For 23847, we want Tor to be able to shut down and then restart in
the same process.  Here's a patch to make the Tor binary do that.
To test it, you need to build with --enable-restart-debugging, and
then you need to set the environment variable TOR_DEBUG_RESTART.
With this option, Tor will then run for 5 seconds, then restart
itself in-process without exiting.  This only happens once.

You can change the 5-second interval using
TOR_DEBUG_RESTART_AFTER_SECONDS.

Implements ticket 24583.

af8cadf3a9 Remove false positives from channel_is_client() 
Fix a set of false positives where relays would consider connections
to other relays as being client-only connections (and thus e.g.
deserving different link padding schemes) if those relays fell out

authenticated as a relay.
