6eb1b8da0a Turn 'mainloop' into a subsystem.
We need a little refactoring for this to work, since the
initialization code for the periodic events assumes that libevent is
already initialized, which it can't be until it's configured.

This change, combined with the previous ones, lets other subsystems
declare their own periodic events, without mainloop.c having to know
about them.  Implements ticket 30293.

ab6ddc7a33 practracker: split shutdown code out of main.c
This is necessary to get the number of includes in main.c back under
control.  (In the future, we could just use the subsystem manager for
this kind of stuff.)

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.

b3416476b4 Remove all uses of weak_rng.
I'm not removing the weak_rng code itself yet, since it is possible
that we will want to revert one of these.

b0ae6a332a Add bootstrap tracker subsystem
Add a tracker for bootstrap progress, tracking events related to
origin circuit and ORCONN states.  This uses the ocirc_event and
orconn_event publish-subscribe subsystems.

a0b4fa1f16 Add origin circuit event pubsub system
Add a publish-subscribe subsystem to publish messages about changes to
origin circuits.

Functions in circuitbuild.c and circuitlist.c publish messages to this
subsystem.

Move circuit event constants out of control.h so that subscribers
don't have to include all of control.h to take actions based on
messages they receive.

271b50f54a Add ORCONN event pubsub system
Add a publish-subscribe subsystem to publish messages about changes to
OR connections.

connection_or_change_state() in connection_or.c and
control_event_or_conn_event() in control.c publish messages to this
subsystem via helper functions.

Move state constants from connection_or.h to orconn_state.h so that
subscribers don't have to include all of connection_or.h to take
actions based on changes in OR connection state.  Move event constants
from control.h for similar reasons.

Part of ticket 27167.

35509978dd Add new Process subsystem.
This patch adds a new Process subsystem for running external programs in
the background of Tor. The design is focused around a new type named
`process_t` which have an API that allows the developer to easily write
code that interacts with the given child process. These interactions
includes:

- Easy API for writing output to the child process's standard input
  handle.
- Receive callbacks whenever the child has output on either its standard
  output or standard error handles.
- Receive callback when the child process terminates.

We also support two different "protocols" for handling output from the
child process. The default protocol is the "line" protocol where the
process output callbacks will be invoked only when there is complete
lines (either "\r\n" or "\n" terminated). We also support the "raw"
protocol where the read callbacks will get whatever the operating system
delivered to us in a single read operation.

This patch does not include any operating system backends, but the Unix
and Windows backends will be included in separate commits.
