10a6390deb Add controller getinfo exit-policy/reject-private
exit-policy/reject-private lists the reject rules added by
ExitPolicyRejectPrivate. This makes it easier for stem to
display exit policies.

Add unit tests for getinfo exit-policy/*.

Completes ticket #17183. Patch by "teor".

66fac9fbad Block OutboundBindAddressIPv[4|6]_ and configured ports on exit relays
Modify policies_parse_exit_policy_reject_private so it also blocks
the addresses configured for OutboundBindAddressIPv4_ and
OutboundBindAddressIPv6_, and any publicly routable port addresses
on exit relays.

Add and update unit tests for these functions.

IPv4 and IPv6 relay addresses, and the addresses of local interfaces.

c73c5a293f Refactor policies_parse_exit_policy_internal
Move the code that rejects publicly routable exit relay addresses
to policies_parse_exit_policy_reject_private. Add
addr_policy_append_reject_addr_list and use it to reject interface
addresses.

This removes the duplicate reject checks on local_address and
ipv6_local_address, but duplicates will be removed by
exit_policy_remove_redundancies at the end of the function.

This also removes the info-level logging on rejected interface
addresses. Instead, log a debug-level message in
addr_policy_append_reject_addr.

This simplifies policies_parse_exit_policy_internal and prepares for
reporting these addresses over the control port in #17183.

f19d6b81c8 Fixup #17638: ignore EINVAL from FreeBSD jails without ::1
In my testing, an IPv6-only FreeBSD jail without ::1 returned EINVAL
from tor_ersatz_socketpair. Let's not fail the unit test because of
this - it would only ever use tor_socketpair() anyway.

53ec840bdf Make tor_ersatz_socketpair work on IPv6-only systems
(But it won't work on some systems without IPv4/IPv6 localhost
(some BSD jails) by design, to avoid creating sockets on routable
IP addresses. However, those systems likely have the AF_UNIX socketpair,
which tor prefers.)

Fixes bug #17638; bugfix on a very early tor version,
earlier than 22dba27d8d (23 Nov 2004) / svn:r2943.

71fd66c866 Fix unit tests on systems without IPv4 or localhost addresses
Make unit tests pass on IPv6-only systems, and systems without
localhost addresses (like some FreeBSD jails).

Fixes:
* get_if_addrs_ifaddrs: systems without localhost
* get_if_addrs_ioctl: only works on IPv4 systems
* socket: check IPv4 and IPv6, skip on EPROTONOSUPPORT
* socketpair_ersatz: uses IPv4, skip on EPROTONOSUPPORT

Fixes bug #17632; bugfix on unit tests in 0.2.7.3-rc.
c464a36772 was a partial fix for this issue in #17255;
it was released in unit tests in 0.2.7.4-rc.

85bb71049a Fix a startup time assert caused by periodic events not being initialized.
Loading a on disk bridge descriptor causes a directory download to be
scheduled, which asserts due to the periodic events not being
initialized yet.

Fixes bug #17635, not in any released version of tor.

84b3350c83 Be more conservative in scanning the list of pending streams
Now we only re-scan the list in the cases we did before: when we
have a new circuit that we should try attaching to, or when we have
added a new stream that we haven't tried to attach yet.

This is part of 17590.

b1d56fc589 Decouple ..attach_circuit() from most of its callers.
Long ago we used to call connection_ap_handshake_attach_circuit()
only in a few places, since connection_ap_attach_pending() attaches
all the pending connections, and does so regularly.  But this turned
out to have a performance problem: it would introduce a delay to
launching or connecting a stream.

We couldn't just call connection_ap_attach_pending() every time we
make a new connection, since it walks the whole connection list.  So
we started calling connection_ap_attach_pending all over, instead!
But that's kind of ugly and messes up our callgraph.

So instead, we now have connection_ap_attach_pending() use a list
only of the pending connections, so we can call it much more
frequently.  We have a separate function to scan the whole
connection array to see if we missed adding anything, and log a
warning if so.

Closes ticket #17590

Yes, even if it has to return a non-multiple.  This prevents us from
