Raise common code for "detach this stream and try it with a different circuit" into a separate function; make that function handle controller-managed streams right.

Separate reverse-virtual-address-map entries into ipv4 and hostname slots. Otherwise if you ask me to map "some IPv4 address" to foo.onion, I might tell you that I already mapped "bar.virtual" to foo.onion


svn:r3730

Rename unused-address functions to virtual address; this is more accurate.  Also, include almost-right implementation of reusing dont-care mappings.  (It is still kind of wrong because it does not take type into account.)


svn:r3728

Implement "Dont-Care" from addresses to MapAddress control message.  For safety, refuse to launch connections to unmapped addresses in the dont-care range.


svn:r3725

svn:r3723

Revise all calls to connection_edge_end to avoid sending MISC, and to take errno into account where possible.


svn:r3720

Forward-port new reasons; clean up code more; add code to convert new reasons to SOCKS5 reply codes; add code to convert errnos to reasons.  New code still needs to get invoked.


svn:r3719

svn:r3684

Clarify comment. Use CONN_IS_EDGE more. Try to be more zealous about calling connection_edge_end when things go bad with edge conns in connection.c

Add a new TrackHostExits directive to trigger addressmaps for
certain incoming socks addresses, for sites that break when your exit
keeps changing.
Redo the client-side dns cache so it's just an addressmap too.

svn:r3631

Fix another crash bug found by Jaroslaw--it is possible for dns_resolve to mark a connection to be freed, if the circuit it was attached to fails for some reason.

something goes wrong. this should only be used by people actively
tracking bugs.

apparently when we get an eof, at least sometimes it *does* mean
you'd better not try writing.

to the exit policy of the last hop. Intro and rendezvous circs must
be internal circs, to avoid leaking information. Resolve and connect
streams can use internal circs if they want.

New circuit pooling algorithm: make sure to have enough circs around
to satisfy any predicted ports, and also make sure to have 2 internal
circs around if we've required internal circs lately (with high uptime
if we've seen that lately).

Split NewCircuitPeriod config option into NewCircuitPeriod (30 secs),
which describes how often we retry making new circuits if current ones
are dirty, and MaxCircuitDirtiness (10 mins), which describes how long
we're willing to make use of an already-dirty circuit.

Once rendezvous circuits are established, keep using the same circuit as
long as you attach a new stream to it at least every 10 minutes. (So web
browsing doesn't require you to build new rend circs every 30 seconds.)

Cannibalize GENERAL circs to be C_REND, C_INTRO, S_INTRO, and S_REND
circ as necessary, if there are any completed ones lying around when
we try to launch one.

Re-instate the ifdef's to use version-0 style introduce cells, since
there was yet another bug in handling version-1 style. We'll try switching
over again after 0.0.9 is obsolete.

Bugfix: when choosing an exit node for a new non-internal circ, don't take
into account whether it'll be useful for any pending x.onion addresses --
it won't.

Bugfix: we weren't actually publishing the hidden service descriptor when
it became dirty. So we only published it every 20 minutes or so, which
means when you first start your Tor, the hidden service will seem broken.

poll-but-sometimes-select mess.  This will let us use faster async cores
(like epoll, kpoll, and /dev/poll), and hopefully work better on Windows
too.

There are some fairly nasty changes to main.c here; this will almost
certainly break something.  But hey, that's what alphas are for.

because if we are then it's because we already got an end.

make it clearer which warns are bugs,
make the control log event match its specification,
