There's a relay running an alternate Tor version that produces
descriptors without "uptime" line, and the directory authorities don't
include a "v" line for that relay, likely because its platform string
does not include the magic word "Tor".

Fixes #24012.

Implements task-23778.

When we set this field in the update process, we only looked whether
the bridge is contained in the last known bridge network status. We
also need to check whether it has the "Running" flag assigned there.

This is different from relays, because the consensus only lists relays
with the "Running" flag since a couple of years, whereas the bridge
network status lists all known bridges.

Fixes #23467. Spotted by nusenu.

Implements #23548.

Also, added error logging for indexing process.

The timeouts are ncessary, when something unforseen makes the
NodeIndexer.getLatestNodeIndex wait forever.

The system property is 'onionoo.basedir'.  If not set, backwards compatible
defaults apply.  Implements task-14201.

Implements #21427.

Suggested by iwakeh on #22681.

Implements #22681.

to avoid the use of TimeFactory and Time classes.  This also makes
it more obvious where time is changed for making the tests work.

Also resolve errors from not implementing newly introduced methods in
test dummies.
