211e56ad87 Remove redundant descriptor checks for OR/Dir reachability
The ORPort and DirPort must be reachable, or we won't publish a
descriptor.

692828bea5 Decide to advertise begindir support like we decide to advertise DirPort
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.

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.

Also add misbehaving relays to updateFallbackDirs.py blacklist,

or it's been resolved by the download check fixes. (These
relays hang stem's downloader. It's unlikely they'll ever help
clients.)

bff53aabce Remove redundant declarations of MIN
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.

1e553b6c68 Increase number of preemptive internal circuits
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.

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.

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)

a885271c08 Add new tor_assert_nonfatal*() macros.
Unlike tor_assert(), these macros don't abort the process.  They're
good for checking conditions we want to warn about, but which don't
warrant a full crash.

This commit also changes the default implementation for
tor_fragile_assert() to tor_assert_nonfatal_unreached_once().

0630f1982d Add LCOV_EXCL* markers to crypto.c and crypto_s2k.c

unreachable.  Don't use it anywhere you wouldn't add a
tor_fragile_assert().)

0aacc07036 encourage rejected relays to contact us
When the directory authorities refuse a bad relay's descriptor,
encourage the relay operator to contact us. Many relay operators
won't notice this line in their logs, but it's a win if even a
few learn why we don't like what their relay was doing.

Resolves ticket 18760.

I didn't specify a contact mechanism (e.g. an email address), because
every time we've done that in the past, a few years later we noticed
that the code was pointing people to an obsolete contact address.
