238828c92b Add a new GUARD_WAIT state for circuits
This state corresponds to the WAITING_FOR_BETTER_GUARD state; it's
for circuits that are 100% constructed, but which we won't use until
we are sure that we wouldn't use circuits with a better guard.

8da24c99bd Split bridge functions into a new module.
This patch is just:
   * Code movement
   * Adding headers here and there as needed
   * Adding a bridges_free_all() with a call to it.

It breaks compilation, since the bridge code needed to make exactly
2 calls into entrynodes.c internals.  I'll fix those in the next
commit.

Stop discarding consensus flavors and descriptors we wanted to fetch
Instead, fetch and store consensus flavors and descriptors we wanted to
fetch.

And serve them if we are a directory cache (or authority).

8293356ad9 hs: Refactor rend_data_t for multi version support
In order to implement proposal 224, we need the data structure rend_data_t to
be able to accomodate versionning that is the current version of hidden
service (2) and the new version (3) and future version.

For that, we implement a series of accessors and a downcast function to get
the v2 data structure. rend_data_t becomes a top level generic place holder.

The entire rend_data_t API has been moved to hs_common.{c|h} in order to
seperate code that is shared from between HS versions and unshared code (in
rendcommon.c).

Closes #19024

aae034d13e Write a bunch of module documentation.
This commit adds or improves the module-level documenation for:

  buffers.c circuitstats.c command.c connection_edge.c control.c
  cpuworker.c crypto_curve25519.c crypto_curve25519.h
  crypto_ed25519.c crypto_format.c dircollate.c dirserv.c dns.c
  dns_structs.h fp_pair.c geoip.c hibernate.c keypin.c ntmain.c
  onion.c onion_fast.c onion_ntor.c onion_tap.c periodic.c
  protover.c protover.h reasons.c rephist.c replaycache.c
  routerlist.c routerparse.c routerset.c statefile.c status.c
  tor_main.c workqueue.c

In particular, I've tried to explain (for each documented module)
what each module does, what's in it, what the big idea is, why it
belongs in Tor, and who calls it.  In a few cases, I've added TODO
notes about refactoring opportunities.

I've also renamed an argument, and fixed a few DOCDOC comments.

a00fee2f54 Ephemeral Single Onion Services must have the NonAnonymous ADD_ONION flag
Tor checks that the flag matches the configured onion service anonymity.

Tor refuses to create unflagged onion service using ADD_ONION, if they
would be non-anonymous. The error is:
512 Tor is in non-anonymous onion mode

Similarly, if the NonAnonymous flag is present, and Tor has the default
anonymous onion config:
512 Tor is in anonymous onion mode

Avoid disclosing exit IP addresses in exit policies by default
From 0.2.7.2-alpha onwards, Exits would reject all the IP addresses
they knew about in their exit policy. But this may have disclosed
addresses that were otherwise unlisted.

Now, only advertised addresses are rejected by default by
ExitPolicyRejectPrivate. All known addresses are only rejected when
ExitPolicyRejectLocalInterfaces is explicitly set to 1.

4f1a04ff9c Replace nearly all XXX0vv comments with smarter ones
So, back long ago, XXX012 meant, "before Tor 0.1.2 is released, we
had better revisit this comment and fix it!"

But we have a huge pile of such comments accumulated for a large
number of released versions!  Not cool.

So, here's what I tried to do:

  * 0.2.9 and 0.2.8 are retained, since those are not yet released.

  * XXX+ or XXX++ or XXX++++ or whatever means, "This one looks
    quite important!"

  * The others, after one-by-one examination, are downgraded to
    plain old XXX.  Which doesn't mean they aren't a problem -- just
    that they cannot possibly be a release-blocking problem.

addd181721 Fix memory leak in TestingEnableCellStatsEvent
Only when we were actually flushing the cell stats to a controller
would we free them.  Thus, they could stay in RAM even after the
circuit was freed (eg if we didn't have any controllers).

Fixes bug 18673; bugfix on 0.2.5.1-alpha.
