0a4bc8fe90 Bug 30992: Track a padding machine ctr to reduce race issues.
This tracking of the instantiation count should eliminate race conditions due
to starting and stopping machines rapidly. Now, we should no longer obey
STOP commands for previous machines.

39f2411b3f Preemptive circs should work with UseEntryGuards 0
Resume being willing to use preemptively-built circuits when
UseEntryGuards is set to 0. We accidentally disabled this feature with
that config setting (in our fix for #24469), leading to slower load times.

Fixes bug 34303; bugfix on 0.3.3.2-alpha.

e46c3d95f4 circuitbuild: Do node checks when counting nodes
Use the node check function to check that there are enough nodes to
select a circuit path.

Adds these checks, which are implied by other code:
* supports EXTEND2 cells,
* does not allow single-hop exits,

Adds these extra checks:
* has a general-purpose routerinfo,
* if it is a direct connection, check reachable addresses.
These checks reduce the node count, but they will never under-count
nodes.

Bridge nodes aren't handled correctly, we'll fix that in the next
commit.

Part of 34200.

766fc86df4 circuitbuild: Do node checks when choosing exits
And check that the correct flags are passed when choosing exits.

Adds the following checks for exits:
* must support EXTEND2 cells,
* must have an ntor circuit crypto key,
* can't require the guard flag,
* can't be a direct connection.

All these checks are already implied by other code.

280195f414 nodelist: Move the v3 onion service rendezvous check
And delete a loop that is now empty. This change should improve tor's

every node in every circuit path.

c116728209 Use __attribute__((fallthrough)) rather than magic GCC comments.
GCC added an implicit-fallthrough warning a while back, where it
would complain if you had a nontrivial "case:" block that didn't end
with break, return, or something like that.  Clang recently added
the same thing.

GCC, however, would let you annotate a fall-through as intended by
any of various magic "/* fall through */" comments.  Clang, however,
only seems to like "__attribute__((fallthrough))".  Fortunately, GCC
accepts that too.

A previous commit in this branch defined a FALLTHROUGH macro to do
the right thing if GNUC is defined; here we replace all of our "fall
through" comments with uses of that macro.

This is an automated commit, made with the following perl one-liner:

  #!/usr/bin/perl -i -p
  s#/\* *falls? ?thr.*?\*/#FALLTHROUGH;#i;

(In order to avoid conflicts, I'm applying this script separately to
each maint branch. This is the 0.4.3 version.)
