Client side, when a descriptor is finally fetched and stored in the cache, we
then go over all pending SOCKS request for that descriptor. If it turns out
that the intro points are unusable, we close the first SOCKS request but not
the others for the same .onion.
This commit makes it that we'll close all SOCKS requests so we don't let
hanging the other ones.
It also fixes another bug which is having a SOCKS connection in RENDDESC_WAIT
state but with a descriptor in the cache. At some point, tor will expire the
intro failure cache which will make that descriptor usable again. When
retrying all SOCKS connection (retry_all_socks_conn_waiting_for_desc()), we
won't end up in the code path where we have already the descriptor for a
pending request causing a BUG().
Bottom line is that we should never have pending requests (waiting for a
descriptor) with that descriptor in the cache (even if unusable).
Fixees #27410.

All node_get_all_orports() does is allocate and return a smartlist
with at most two tor_addr_port_t members that match ORPort's of
node configuration. This is harmful for memory efficiency, as it
allocates the same stuff every time it is called. However,
node_is_a_configured_bridge() does not need to call it, as it
already has all the information to check if there is configured
bridge for a given node.
The new code is arranged in a way that hopefully makes each succeeding
linear search through bridge_list less likely.
This commit makes it that the authorized clients in the descriptor are in
random order instead of ordered by how they were read on disk.

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.
Track bootstrap phase (enumerated by bootstrap_status_t) independently
from the bootstrap progress (which can represent intermediate
progress). This allows control_event_bootstrap_problem() to avoid
doing a linear search through the bootstrap progress space to find the
current bootstrap phase.
Move the mostly-invariant part of control_event_boostrap() into a
helper control_event_bootstrap_core(). The helper doesn't modify any
state beyond doing logging and control port notifications.
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.

There are three reasons we use a cached_dir_t to hold a consensus:
1. to serve that consensus to a client
2. to apply a consensus diff to an existing consensus
3. to send the consensus to a controller.
But case 1 is dircache-only. Case 2 and case 3 both fall back to
networkstatus_read_cached_consensus(). So there's no reason for us
to store this as a client. Avoiding this saves about 23% of our RAM
usage, according to our experiments last month.
This is, semantically, a partial revert of e5c608e535.
Fixes bug 27247; bugfix on 0.3.0.1-alpha.
We already had fallback code for "dir/status-vote/current/consensus"
to read from disk if we didn't have a cached_dir_t available. But
there's a function in networkstatus_t that does it for us, so let's
do that.
Return a newly allocated fake client authorization object instead of taking
the object as a parameter.

When reloading tor, check if our the configured client authorization have
changed from what we previously had. If so, republish the updated descriptor.

Previously, the validation by decoding a created descriptor was disabled
because the interface had to be entirely changed and not implemented at the
time.
This commit re-enabled it because it is now implemented.

Parse the client authorization section from the descriptor, use the client
private key to decrypt the auth clients, and then use the descriptor cookie to
decrypt the descriptor.

This commit refactors the existing decryption code to make it compatible with
a new logic for when the client authorization is enabled.

Because this secret data building logic is not only used by the descriptor
encoding process but also by the descriptor decoding, refactor the function to
take both steps into account.

Previously, we encrypted the descriptor without the descriptor cookie. This
commit, when the client auth is enabled, the descriptor cookie is always used.
I also removed the code that is used to generate fake auth clients because it
will not be used anymore.

We need to generate all the related keys when building the descriptor, so that
we can encrypt the descriptor.
