Redefine the set of bootstrap phases to allow display of finer-grained
progress in the early connection stages of connecting to a relay.
This includes adding intermediate phases for proxy and PT connections.
Also add a separate new phase to indicate obtaining enough directory
info to build circuits so we can report that independently of actually
initiating an ORCONN to build the first application circuit.
Previously, we would claim to be connecting to a relay when we had
merely finished obtaining directory info.
Part of ticket 27167.
Replace a few invocations of control_event_bootstrap() with calls from
the bootstrap tracker subsystem. This mostly leaves behavior
unchanged. The actual behavior changes come in the next commit.
Part of ticket 27167.
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.
Part of ticket 27167.
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.

This patch adds support for the new STATUS message that PT's can emit
from their standard out. The STATUS message uses the `config_line_t` K/V
format that was recently added in Tor.
See: https://bugs.torproject.org/28846
This patch changes the LOG pluggable transport message to use the recent
K/V parser that landed in Tor. This allows PT's to specify the log
severity level as well as the message. A mapping between the PT log
severity levels and Tor's log serverity level is provided.
See: https://bugs.torproject.org/28846
This patch changes our EVENT_TRANSPORT_LOG event to be EVENT_PT_LOG. The
new message includes the path to the PT executable instead of the
transport name, since one PT binary can include multiple transport they
sometimes might need to log messages that are not specific to a given
transport.
See: https://bugs.torproject.org/28179
This patch adds support for the "LOG" protocol message from a pluggable
transport. This allows pluggable transport developers to relay log
messages from their binary to Tor, which will both emit them as log
messages from the Tor process itself, but also pass them on via the
control port.

Existing cached directory information can cause misleadingly high
bootstrap percentages. To improve user experience, defer reporting of
directory information progress until at least one connection has
succeeded to a relay or bridge.
Closes ticket 27169.
Simplify control_event_bootstrap() by making it return void again. It
is currently a fairly complicated function, and it's made more
complicated by returning an int to signal whether it logged at NOTICE
or INFO.
The callers conditionally log messages at level NOTICE based on this
return value. Change the callers to unconditionally log their verbose
human-readable messages at level INFO to keep NOTICE logs less
cluttered.
This partially reverts the changes of #14950.
This commit won't build yet -- it just puts everything in a slightly
more logical place.
The reasoning here is that "src/core" will hold the stuff that every (or
nearly every) tor instance will need in order to do onion routing.
Other features (including some necessary ones) will live in
"src/feature". The "src/app" directory will hold the stuff needed
to have Tor be an application you can actually run.
This commit DOES NOT refactor the former contents of src/or into a
logical set of acyclic libraries, or change any code at all. That
will have to come in the future.
We will continue to move things around and split them in the future,
but I hope this lays a reasonable groundwork for doing so.
