3b8216f215 Use fascist firewall and ClientUseIPv4 for bridge clients
Bridge clients ignore ClientUseIPv6, acting as if it is always 1.
This preserves existing behaviour.

Make ClientPreferIPv6OR/DirPort auto by default:
 * Bridge clients prefer IPv6 by default.
 * Other clients prefer IPv4 by default.
This preserves existing behaviour.

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.

2212530bf5 Prop210: Close excess connections once a consensus is downloading
Once tor is downloading a usable consensus, any other connection
attempts are not needed.

Choose a connection to keep, favouring:
* fallback directories over authorities,
* connections initiated earlier over later connections

Close all other connections downloading a consensus.

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.

1193647ac8 Replace 'SOCKSPort' with 'SocksPort'
When applying changes from proposal 171 Nick renamed SocksPort to SOCKSPort,
and SocksListenAddress to SOCKSListenAddress...

  https://gitweb.torproject.org/tor.git/commit/?id=891ccd3cd0690e83f1dc4dde7698c3bd9d7fe98d

However, this didn't change the option itself in tor (it's still SocksPort),
and wasn't even uniform in the man page. Functionally this doesn't matter
(tor's config options are case insensitive) but this is a pretty clear
regression.

098b82c7b2 ExitPolicyRejectPrivate rejects local IPv6 address and interface addresses
ExitPolicyRejectPrivate now rejects more local addresses by default:
 * the relay's published IPv6 address (if any), and

trust connections originating from localhost.

d3358a0a05 ExitPolicy accept6/reject6 produces IPv6 wildcard addresses only

359faf5e4b New TestingDirAuthVote{Exit,Guard,HSDir}IsStrict flags
"option to prevent guard,exit,hsdir flag assignment"

"A node will never receive the corresponding flag unless
that node is specified in the
TestingDirAuthVote{Exit,Guard,HSDir} list, regardless of
its uptime, bandwidth, exit policy, or DirPort".

Patch modified by "teor": VoteOnHidServDirectoriesV2
is now obsolete, so TestingDirAuthVoteHSDir always
votes on HSDirs.

0cb82013cc Fix TestingDirAuthVoteHSDir docs: HSDir flag needs DirPort
Fix an error in the manual page and comments for
TestingDirAuthVoteHSDir, which suggested that a
HSDir required "ORPort connectivity". While this is true,
it is in no way unique to the HSDir flag. Of all the flags,
only HSDirs need a DirPort configured in order for the
authorities to assign that particular flag.
