Initial version of circuit-based cell queues. Instead of hammering or_conns with piles of cells, queue cells on their corresponding circuits, and append them to the or_conn as needed. This seems to work so far, but needs a bit more work. This will break the memory-use-limitation patch for begin_dir conns: the solution will be a fun but fiddly.

Twiddle TODO around a bit: remove redundant items; mark completed and abandoned items; pull sub-items from redundant items into 0.2.0.x section; move items from aclocal.m4 into TODO; move some TODO items into 098-todo.txt; move one item onto flyspray.
svn:r9785
Remove support for v0 control protocol from 0.2.0.x trunk; send back error when we receive a v0 control message. (Leave "if(v1){...}"blocks indented for now so this patch is easier to read.) ((Finally, the linecount goes _down_ a little.))
svn:r9735
Make all LD_BUG log messsages get prefixed with "Bug: ". Remove manually-generated "Bug: "s from log-messages. (Apparently, we remembered to add them about 40% of the time.)

nt_service_is_stopping should not load the NT service library calls: if they are not loaded, we cannot possibly be a service trying to shut own. Bug found by "norvid" on or-talk. Also, rename function to something slightly less error-prone.

Niels has accepted the patch from Scott Lamb to implement better signal handling: I can take "get the pthread_sigprocmask situation under control" off my plate.

Note another fun way that we could replace the more automatable parts of arma with software, thus leaving the less automatable bits free to do less automatable stuff.

Make remap stream events have a souce; make them generated every time we get a successful connected or resolved cell. Also change reported stream target address to IP consistently when we get the IP from an exit node.

Fix a longstanding dnsworker-related bug: when we decide to kill a DNS worker for having been in use too long, and we independently decide to close one of the exit connections waiting for that DNS worker (perhaps because we got an END relay cell), it was possible for us to try to double-free the connection. We were smart enough to detect this and assert, but not smart enough to fix this bug before now. This should resolve bug 390. Backport candidate.

Implement proposal 106: stop requiring clients to have certificates, and stop checking for nicknames in certificates. [See proposal 106 for rationale.] Also improve messages when checking TLS handshake, to re-resolve bug 382.
svn:r9568
Write the entry guards section of path-spec; note a possible bug in cirbuitbuild.c; add a const; defer work on torrc.complete to be part of a bigger config documentation reorg.

This one is a little tricky. Our BEGIN_DIR implementation has a
problem: the dirserv conns will decide they can flush all their data
immediately, since the edge_conns will read greedily.
For our 0.1.2 workaround, we track which or_conn a bridged dirserv
conn is attached to, and stop writing when its outbuf is too full, and
start writing again when the or_conn's outbuf empties out a little.
This requires a bit of pointer management. Let's hope it works.

TODO items: Defer complicated solution to BEGIN_DIR memory problem; mark the simple one partially implemented; note a forward compatibility TODO.
svn:r9431
Implement SOCKS_BAD_HOSTNAME status event. Defer remaining status events. Clean up control-spec.txt a little, and fill in recommendations for events.
svn:r9374
Add some comments to TODO about nastiness of getting data-choking to work with directory bridges; propose a better solution for later, and some simpler solutions for now.
svn:r9321
Add (and specify) a BadDirectory flag to networkstatuses, so authorities can tell clients that some caches are broken. Also, implement an as-yet-unused function to estimate how many bytes will be sent on a directory connection.
