c281c03654 If both IPv4 and IPv6 addresses could be used, choose one correctly 
If there is a node, use node_ipv6_or/dir_preferred().
If there is no node, use fascist_firewall_prefer_ipv6_or/dirport().

c213f277cd Make bridge clients prefer the configured bridge address 
When ClientPreferIPv6ORPort is auto, bridges prefer the configured
bridge ORPort address. Otherwise, they use the value of the option.
Other clients prefer IPv4 ORPorts if ClientPreferIPv6ORPort is auto.

When ClientPreferIPv6DirPort is auto, all clients prefer IPv4 DirPorts.

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.

3f41318472 Add crypto_rand_int_range() and use it 
Incidently, this fixes a bug where the maximum value was never used when
only using crypto_rand_int(). For instance this example below in
rendservice.c never gets to INTRO_POINT_LIFETIME_MAX_SECONDS.

  int intro_point_lifetime_seconds =
    INTRO_POINT_LIFETIME_MIN_SECONDS +
    crypto_rand_int(INTRO_POINT_LIFETIME_MAX_SECONDS -
                    INTRO_POINT_LIFETIME_MIN_SECONDS);

0f31080d63 Stop checking for torrc state files generated by very old Tor versions 
These haven't worked in so long that if you had a state file of this
kind, the guards in it would be so old that you wouldn't use them
anyway.

b101f4e98c Control: getinfo entry-guards report down-since 
If the guard unreachable_since variable was set, the status "up" was
reported which is wrong. This adds the "down" status followed by the
unreachable_since time value.

Fixes #14184

4cb59ceb8e Only retry connecting to configured bridges 
After connectivity problems, only try connecting to bridges which
are currently configured; don't mark bridges which we previously
used but are no longer configured.  Fixes 14216.  Reported by

33df3e37ff Allow two ISO times to appear in EntryGuardDownSince. 
When I made time parsing more strict, I broke the
EntryGuardDownSince line, which relied on two concatenated ISO times
being parsed as a single time.

Fixes bug 14136. Bugfix on 7984fc1531. Bug not in any released
version of Tor.

fb68f50761 Lower the delay before saving guard status to disk 
"Maybe this time should be reduced, since we are considering
guard-related changes as quite important? It would be a pity to
settle on a guard node, then close the Tor client fast and lose that
information."

Closes 12485.

ff42222845 Improve DIRINFO flags' usage comments

which take them as arguments. Replace 0 with NO_DIRINFO in a function call
