Avoid an error in the fallback script when a fallback doesn't have any uptime
Sometimes, the fallback generation script doesn't add attributes to the
fallbacks in the list. If this happens, log an error, and avoid selecting
that fallback.

This is a rare issue: it should not change selection behaviour.

Fixes issue #20945.

Allow fallbacks serving consensuses that expired less than 24 hours ago
This works around #20909, where relays serve stale consensuses for a short
time, and then recover.

Avoid checking fallback candidates' DirPorts if they are down in OnionOO
Exclude relays that have been down for 1 or more days from the fallback
candidate list.

When a relay operator has multiple relays, this prioritises relays that are
up over relays that are down.

Require fallback directories to have the same address and port for 7 days
7 days is a tradeoff between the expected time between major Tor releases,
which is 6 months, and the number of relays with enough stability.

Relays whose OnionOO stability timer is reset on restart by bug #18050
should upgrade to Tor 0.2.8.7 or later, which has a fix for this issue.

Closes ticket #20880; maintains short-term fix in e220214 in tor-0.2.8.2-alpha.

5927ed8d33 checkSpace.pl now forbids more identifiers.
The functions it warns about are:
  assert, memcmp, strcat, strcpy, sprintf, malloc, free, realloc,
  strdup, strndup, calloc.

Also, fix a few lingering instances of these in the code. Use other
conventions to indicate _intended_ use of assert and
malloc/realloc/etc.

26146dbe9e Comment-out fallbacks in a way the stem fallback parser understands
If we manually remove fallbacks in C by adding '/*' and '*/' on separate
lines, stem still parses them as being present, because it only looks at
the start of a line.

Add a comment to this effect in the generated source code.
