But when clients are just starting, make them try each bridge a few times
before giving up on it.
These changes make the bridge download schedules more explicit: before
17750, they relied on undocumented behaviour and specific schedule
entries. (And between 17750 and this fix, they were broken.)
Fixes 23347, not in any released version of tor.
We were always incrementing bridge download statuses on each attempt,
but we were using the "increment on failure" functions to do it.
And we never incremented them on failure.
No behaviour change.
The download schedule tells Tor to wait 15 minutes before downloading
bridge descriptors. But 17750 made Tor ignore that and start immediately.
Since we fixed 17750, Tor waits 15 minutes for bridge client bootstrap,
like the schedule says.
This fixes the download schedule to start immediately, and to try each
bridge 3 times in the first 30 seconds. This should make bridge bootstraps
more reliable.
Fixes 23347.
It is possible that two descriptor upload requests are launched in a very
short time frame which can lead to the second request finishing before the
first one and where that first one will make the HSDir send back a 400
malformed descriptor leading to a warning.
To avoid such, cancel all active directory connections for the specific
descriptor we are about to upload.
Note that this race is still possible on the HSDir side which triggers a log
info to be printed out but that is fine.

When option validation or transition is happening, there are no
"current options" -- only "old options" and "maybe new options".
Looking at get_options() is likely a mistake, so have a nonfatal
assertion let us know if we do that.
Closes 22281.
Because we can get a RENDEZVOUS2 cell before the INTRODUCE_ACK, we need to
correctly handle the circuit purpose REND_JOINED that is not change its
purpose when we get an INTRODUCE_ACK and simply close the intro circuit
normally.

This test is important because it tests that upload_descriptor_to_all()
is in synch with pick_hsdir_v3(). That's not the case for the
reachability test which just compares the responsible hsdir sets.
