Log a notice just before the script is about to perform a
potentially time-consuming operation
Clarify the warning when py2-ipaddress isn't found
Make log levels more consistent
No behavioural change (just logging)
Decide to advertise begindir support in a similar way to how
we decide to advertise DirPort.
Fix up the associated descriptor-building unit tests.
Resolves#18616, bugfix on 0c8e042c30 in #12538 in 0.2.8.1-alpha.
As well as the existing reports of IPv6 address additions or removals,
the script now warns when keys change but IPv4:ORPort or
IPv6:IPv6ORPort remain the same.
Existing checks for other whitelist detail changes have also
been re-worded and upgraded to warnings.
This makes it easier for changes to be identified so operators can
be contacted to confirm whether the change is stable.
Also add misbehaving relays to updateFallbackDirs.py blacklist,
but leave them commented out in case it's a transient issue,
or it's been resolved by the download check fixes. (These
relays hang stem's downloader. It's unlikely they'll ever help
clients.)
Apparently somewhere along the line we decided that MIN might be
missing.
But we already defined it (if it was missing) in compat.h, which
everybody includes.
Closes ticket 18889.
When we connect to a hidden service as a client we may need three internal
circuits, one for the descriptor retrieval, introduction, and rendezvous.
Let's try to make sure we have them. Closes#13239.

Use IP address, effective family, and contact info to
discover and limit fallbacks to one per operator.
Also analyse netblock, ports, IP version, and Exit flag,
and print the results. Don't exclude any fallbacks from
the list because of netblocks, ports, IP version, or
Exit flag.
But as advertised bandwidth is controlled by relays,
use consensus weight and median weight to bandwidth ratio
to approximate measured bandwidth.
Includes minor comment changes and parameter reordering.
Previously, we would cut the list down to 100 fallbacks,
then check if they could serve a consensus, and comment
them out if they couldn't.
This would leave us with fewer than 100 active fallbacks.
Now, we stop when there are 100 active fallbacks.
Also count fallbacks with identical contact info.
Also fix minor logging issues.
Give each fallback a set weight of 10.0 for client selection.
Fallbacks must have at least 3000 consensus weight.
This is (nominally) 100 times the expected extra load of
20 kilobytes per second (50 GB per month).
Fixes issue #17905.
Improve the download test:
* Allow IPv4 DirPort checks to be turned off.
* Add a timeout to stem's consensus download.
* Actually check for download errors, rather than ignoring them.
* Simplify the timeout and download error checking logic.
Tweak whitelist/blacklist checks to be more robust.
Improve logging, make it warn by default.
Cleanse fallback comments more thoroughly:
* non-printables (yes, ContactInfo can have these)
* // comments (don't rely on newlines to prevent // */ escapes)
