ba7691071e Report fallback directory detail changes when rebuilding list
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.

8b90d45f78 Add fallbacks to white/blacklist from operator responses
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.)

c157a31ee8 Limit fallbacks from the same operator
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.

78ec782f76 Select fallbacks by bandwidth rather than consensus weight
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.

e115523c98 Only count active fallbacks in updateFallbackDirs.py
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.

205a641e1d Remove fallback directory weights
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.

7e1b8ae79c Improve fallback selection and output
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)

4043f2c95f Adopt the LCOV convention for marking lines as unreachable by tests.
Document this convention.

Add a script to post-process .gcov files in order to stop nagging us
about excluded lines.

Teach cov-diff to handle these post-processed files.

Allow fallback directories which have been stable for 7 days
to work around #18050, which causes relays to submit descriptors
with 0 DirPorts when restarted. (Particularly during Tor version
upgrades.)

Ignore low fallback directory count in alpha builds.

4c1c2a313d Add Fallback Directory Candidate Selection Script
"Tor has included a feature to fetch the initial consensus from nodes
 other than the authorities for a while now. We just haven't shipped a
 list of alternate locations for clients to go to yet.

 Reasons why we might want to ship tor with a list of additional places
 where clients can find the consensus is that it makes authority
 reachability and BW less important.

 We want them to have been around and using their current key, address,
 and port for a while now (120 days), and have been running, a guard,
 and a v2 directory mirror for most of that time."

Features:
* whitelist and blacklist for an opt-in/opt-out trial.
* excludes BadExits, tor versions that aren't recommended, and low
  consensus weight directory mirrors.
* reduces the weighting of Exits to avoid overloading them.
* places limits on the weight of any one fallback.
* includes an IPv6 address and orport for each FallbackDir, as
  implemented in #17327. (Tor won't bootstrap using IPv6 fallbacks
  until #17840 is merged.)
* generated output includes timestamps & Onionoo URL for traceability.
* unit test ensures that we successfully load all included default
  fallback directories.

Closes ticket #15775. Patch by "teor".
