5f7df92571 Remove support for unsigned time_t
We've never actually tested this support, and we should probably assume
it's broken.

To the best of my knowledge, only OpenVMS has this, and even on
OpenVMS it's a compile-time option to disable it.  And I don't think
we build on openvms anyway.  (Everybody else seems to be working
around the 2038 problem by using a 64-bit time_t, which won't expire
for roughly 292 billion years.)

Closes ticket 18184.

2d33d192fc Add ClientUseIPv4 and ClientPreferIPv6DirPort torrc options
ClientUseIPv4 0 tells tor to avoid IPv4 client connections.
ClientPreferIPv6DirPort 1 tells tor to prefer IPv6 directory connections.

Refactor policy for IPv4/IPv6 preferences.

Fix a bug where node->ipv6_preferred could become stale if
ClientPreferIPv6ORPort was changed after the consensus was loaded.

Update documentation, existing code, add unit tests.

bca7083e82 avoid integer overflow in and around smartlist_ensure_capacity.
This closes bug 18162; bugfix on a45b131590, which fixed a related
issue long ago.

In addition to the #18162 issues, this fixes a signed integer overflow
in smarltist_add_all(), which is probably not so great either.

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".

35bbf2e4a4 Prop210: Add schedules for simultaneous client consensus downloads
Prop210: Add attempt-based connection schedules

Existing tor schedules increment the schedule position on failure,
then retry the connection after the scheduled time.

To make multiple simultaneous connections, we need to increment the
schedule position when making each attempt, then retry a (potentially
simultaneous) connection after the scheduled time.

(Also change find_dl_schedule_and_len to find_dl_schedule, as it no
longer takes or returns len.)

Prop210: Add multiple simultaneous consensus downloads for clients

Make connections on TestingClientBootstrapConsensus*DownloadSchedule,
incrementing the schedule each time the client attempts to connect.

Check if the number of downloads is less than
TestingClientBootstrapConsensusMaxInProgressTries before trying any
more connections.

07cca627ea Fix backtrace compilation on FreeBSD
On FreeBSD backtrace(3) uses size_t instead of int (as glibc does). This
causes integer precision loss errors when we used int to store its
results.

The issue is fixed by using size_t to store the results of backtrace(3).

The manual page of glibc does not mention that backtrace(3) returns
negative values. Therefore, no unsigned integer wrapping occurs when its
result is stored in an unsigned data type.

The internal memory allocation and history object counters of the

A new function ensures the memory allocation counter is decreased when a
