b252ffa7cb Downgrade path-bias warning messages to INFO for now.
We've had over two months to fix them, and didn't.  Now we need
0.2.3.x stable.  Yes, it would be cool to get this working in
0.2.3.x, but not at the expense of delaying every other feature that
_does_ work in 0.2.3.x.  We can do a real fix in 0.2.4.

b7c172c9ec Disable extending to private/internal addresses by default
This is important, since otherwise an attacker can use timing info
to probe the internal network.

Also, add an option (ExtendAllowPrivateAddresses) so that
TestingTorNetwork won't break.

Fix for bug 6710; bugfix on all released versions of Tor.

3410a46ebc Move ipv6_preferred from routerinfo_t to node_t.

Add get_configured_bridge_by_orports_digest() and have
get_configured_bridge_by_routerinfo() and
node_is_a_configured_bridge() use it. We now consider all OR ports of
a bridge when looking for it.

Move node_get_*_orport to nodelist.c.

Fix a cut'n'paste error in header of nodelist.h.

Add node_assert_ok().

Add router_get_all_orports(). It's duplicating code from
node_get_all_orports(). Worth fixing at the cost of complicating the
API slightly?

778d90122c Avoid spurious warnings in rend_service_introduce
There was some code in the "err:" block that would always log a
warning, reporting an "unknown error" if we hadn't set err_msg.  But
there were also plenty of "goto err" blocks that did their own
logging, and never set err_msg at all.  Now we should only log when
we have an error message to log.

This fixes bug 6638, from no released Tor version.

d9746bd468 Remove needless flush-on-write code.
Long ago, before we had cell queues, it was necessary to maybe call
connection_handle_write() from connectino_write_to_buf_impl() on OR
connections, so that we wouldn't get into a loop of reading infinite
amounts of data and queueing it all on an outbuf before bothering to
write any data.

If that doesn't sounds like what our code does now, you're right:
right now, we won't stick more than OR_CONN_HIGHWATER bytes of cells
on an outbuf, and we won't suck more than CELL_QUEUE_HIGHWATER_SIZE
cells off any edge connection. So, there's no more call for that
code.

Removing this code will simplify our data flow, and that should be
something we can all get behind.

the part that knows about detecting wildcard addresses addresses --
and makes it into a new function.  The new function is deliberately
not moved or reindented, so that the diff is smaller.

cdd882ee71 Check for stream_id, not conn, on extend cells.
Extend cells aren't allowed to have a stream_id, but we were only
blocking them when they had a stream_id that corresponded to a
connection.  As far as I can tell, this change is harmless: it will
make some kinds of broken clients not work any more, but afaik nobody
actually make a client that was broken in that way.

Found while hunting for other places where we made the same mistake
as in 6271.

telescoping circuit construction into 0.0.2pre8.

dfe03d36c8 Don't infer we have a FooPort from the presence of a FooPort line
Thanks to the changes we started making with SocksPort and friends
in 0.2.3.3-alpha, any of our code that did "if (options->Sockport)"
became wrong, since "SocksPort 0" would make that test true whereas
using the default SocksPort value would make it false.  (We didn't
actually do "if (options->SockPort)" but we did have tests for
TransPort.  When we moved DirPort, ORPort, and ControlPort over to
the same system in 0.2.3.9-alpha, the problem got worse, since our
code is littered with checks for DirPort and ORPort as booleans.

This code renames the current linelist-based FooPort options to
FooPort_lines, and adds new FooPort_set options which get set at
parse-and-validate time on the or_options_t.  FooPort_set is true
iff we will actually try to open a listener of the given type. (I
renamed the FooPort options rather than leave them alone so that
every previous user of a FooPort would need to get inspected, and so
that any new code that forgetfully uses FooPort will need fail to
compile.)

Fix for bug 6507.

2a4a149624 Move to non-recursive make
This gives us a few benefits:
1) make -j clean all
   this will start working, as it should. It currently doesn't.
2) increased parallel build
   recursive make will max out at number of files in a directory,
   non-recursive make doesn't have such a limitation
3) Removal of duplicate information in make files,
   less error prone

I've also slightly updated how we call AM_INIT_AUTOMAKE, as the way
that was used was not only deprecated but will be *removed* in the next
major automake release (1.13).... so probably best that we can continue
to bulid tor without requiring old automake.
(see http://www.gnu.org/software/automake/manual/html_node/Public-Macros.html )
