Shave off another 4.7%: remove a linear search when figuring out which circuits wanted us to open a given OR connection.

conn over and over. that's really bad for memory.

Weasel says circuit_get_by_conn is his main timesink.  Most of its
users were just checking whether OR conns had circuits, so add a
circuit count to OR conns, and check that. One was
circuit_about_to_close_conn, which was doing an O(n^2) series of calls
to get all circs on an OR conn, so make an O(n) function for that.
Finally, circuit_get_by_edge_conn was using it as a sanity test that
has been around for a while but never found any actualy insanity, so
kill that.

circuit_get_by_conn is finally dead, which is good, since it was never
sane to begin with.

separately. It's important to keep them separate because internal
circuits have their last hops picked like middle hops, rather than like
exit hops. So exiting on them will break the user's expectations.

- Stop cannibalizing internal circuits for general exits, and stop
  cannibalizing exit circuits for rendezvous stuff.

- Don't let new exit streams attach to internal circuits.

- When deciding if we have enough circuits for internal and for exit,
  don't count the wrong ones.

- Treat predicted resolves as predicted port 80 exits.

node in mind, we weren't checking to see if that exit node
was already present earlier in the circuit. oops.

to 20+ megs of wasted space.

Efficiency hack: call tor_fix_source_file late, not early.  Add "BUG" domain. Domains are now bitmasks... just in case. Make some err msgs non-general.

Using RAND_pseudo_bytes instead of RAND_bytes is an accident waiting to happen, and does not really speed us up much when we do it.  So stop doing it.

- Add a new extend_info_t datatype to hold information needed to
  extend a circuit (addr,port,keyid,onion_key).  Use it in cpath and
  build_state.  Make appropriate functions take or return it instead of
  routerinfo_t or keyid.

- #if 0 needless check in circuit_get_by_edge_conn; if nobody triggers this
  error in 0.1.0.10, nobody will trigger it.

- Implement new hidden service descriptor format, which contains "extend
  info" for introduction points, along with protocol version list.
  - Parse new format.
  - Generate new format
  - Cache old and new formats alongside each other.
  - Directories serve "old" format if asked in old way, "newest available"
    format if asked in new way.
  - Use new format to find introduction points if possible; otherwise fall
    back.  Keep nickname lists and extendinfo lists in sync.
  - Tests for new format.

- Implement new "v2" INTRODUCE cell format.
  - Accept new format
  - Use new format if we have a versioned service descriptor that says the
    server accepts the new format.

- Add documentation for functions and data types.


svn:r4506

Implement all the rest of the new controller protocol, debug a little, add some new features, add ADDRMAP events.


svn:r4460

Docment or add DOCDOC comments to undocumented functions in src/or.  Make function definition format uniform.

Rename circuit_get_by_stream to circuit_get_by_edge_conn, and actually start using it. Watch out, kids!


svn:r4026

Add a pointer from edge connections to their corresponding circuit (ulp!); add some debugging sanity-checking for cirid_orconn_map stuff
