b3586629c9 Wrap the function we use to run the event loop. 
Doing this lets us remove the event2/event.h header from a few more
modules, particularly in the tests.

652d3a5b66 Remove anything related to the old SocksSockets option 
At this commit, the SocksSocketsGroupWritable option is renamed to
UnixSocksGroupWritable. A deprecated warning is triggered if the old option is
used and tor will use it properly.

Fixes #24343

64149353dd dos: Initial code of Denial of Service mitigation 
This commit introduces the src/or/dos.{c|h} files that contains the code for
the Denial of Service mitigation subsystem. It currently contains basic
functions to initialize and free the subsystem. They are used at this commit.

The torrc options and consensus parameters are defined at this commit and
getters are implemented.

5ea993fa5a Clarify directory and ORPort checking functions. 
In order to make the OR and dir checking functions in router.c less confusing
we renamed some functions and splitted consider_testing_reachability() into
router_should_check_reachability() and router_do_reachability_checks(). Also we
improved the documentation.

Fixes #18918.

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.

Add MainloopStats option. 
This patch adds support for MainloopStats that allow developers to get
main event loop statistics via Tor's heartbeat status messages. The new
status log message will show how many succesful, erroneous, and idle
event loop iterations we have had.
