2b9b694410 Remove config.log from CLEANFILES
Fixes bug 17924; bugfix on 0.2.4.1-alpha.

In ddf5020ea8, we added config.log to CLEANFILES in doc/Makefile.am
so that distcheck would be happy about the presence of doc/config.log.
But when we moved to nonrecursie makefiles in 2a4a149624, we
accidentally left that filename unchanged, so that it referred to
config.log instead.

Patch from cypherpunks.

978210d5a8 Wait for busy authorities/fallbacks rather than ignoring excluded nodes
Applies the 6c443e987d fix to router_pick_directory_server_impl.

6c443e987d applied to directory servers chosen from the consensus,
and was:
"Tweak the 9969 fix a little

If we have busy nodes and excluded nodes, then don't retry with the
excluded ones enabled. Instead, wait for the busy ones to be nonbusy."

4c1c2a313d Add Fallback Directory Candidate Selection Script
"Tor has included a feature to fetch the initial consensus from nodes
 other than the authorities for a while now. We just haven't shipped a
 list of alternate locations for clients to go to yet.

 Reasons why we might want to ship tor with a list of additional places
 where clients can find the consensus is that it makes authority
 reachability and BW less important.

 We want them to have been around and using their current key, address,
 and port for a while now (120 days), and have been running, a guard,
 and a v2 directory mirror for most of that time."

Features:
* whitelist and blacklist for an opt-in/opt-out trial.
* excludes BadExits, tor versions that aren't recommended, and low
  consensus weight directory mirrors.
* reduces the weighting of Exits to avoid overloading them.
* places limits on the weight of any one fallback.
* includes an IPv6 address and orport for each FallbackDir, as
  implemented in #17327. (Tor won't bootstrap using IPv6 fallbacks
  until #17840 is merged.)
* generated output includes timestamps & Onionoo URL for traceability.
* unit test ensures that we successfully load all included default
  fallback directories.

Closes ticket #15775. Patch by "teor".
OnionOO script by "weasel", "teor", "gsathya", and "karsten".

35bbf2e4a4 Prop210: Add schedules for simultaneous client consensus downloads
Prop210: Add attempt-based connection schedules

Existing tor schedules increment the schedule position on failure,
then retry the connection after the scheduled time.

To make multiple simultaneous connections, we need to increment the
schedule position when making each attempt, then retry a (potentially
simultaneous) connection after the scheduled time.

(Also change find_dl_schedule_and_len to find_dl_schedule, as it no
longer takes or returns len.)

Prop210: Add multiple simultaneous consensus downloads for clients

Make connections on TestingClientBootstrapConsensus*DownloadSchedule,
incrementing the schedule each time the client attempts to connect.

Check if the number of downloads is less than
TestingClientBootstrapConsensusMaxInProgressTries before trying any
more connections.

07cca627ea Fix backtrace compilation on FreeBSD
On FreeBSD backtrace(3) uses size_t instead of int (as glibc does). This
causes integer precision loss errors when we used int to store its
results.

The issue is fixed by using size_t to store the results of backtrace(3).

The manual page of glibc does not mention that backtrace(3) returns
negative values. Therefore, no unsigned integer wrapping occurs when its
result is stored in an unsigned data type.

91ab2ac5aa Assert that memory held by rephist is freed
The internal memory allocation and history object counters of the
reputation code can be used to verify the correctness of (part of) the
code. Using these counters revealed an issue where the memory allocation
counter is not decreased when the bandwidth arrays are freed.

A new function ensures the memory allocation counter is decreased when a
bandwidth array is freed.

This commit also removes an unnecessary cast which was found while
working on the code.

e9bf584694 Format IPv6 policies correctly.
Previously we'd suppressed the mask-bits field in the output when
formatting a policy if it was >=32.  But that should be a >=128 if
we're talking about IPv6.

Since we didn't put these in descriptors, this bug affects only log
messages and controller outputs.

Fix for bug 16056.  The code in question was new in 0.2.0, but the
bug was introduced in 0.2.4 when we started supporting IPv6 exits.

b1d56fc589 Decouple ..attach_circuit() from most of its callers.
Long ago we used to call connection_ap_handshake_attach_circuit()
only in a few places, since connection_ap_attach_pending() attaches
all the pending connections, and does so regularly.  But this turned
out to have a performance problem: it would introduce a delay to
launching or connecting a stream.

We couldn't just call connection_ap_attach_pending() every time we
make a new connection, since it walks the whole connection list.  So
we started calling connection_ap_attach_pending all over, instead!
But that's kind of ugly and messes up our callgraph.

So instead, we now have connection_ap_attach_pending() use a list
only of the pending connections, so we can call it much more
frequently.  We have a separate function to scan the whole
connection array to see if we missed adding anything, and log a
warning if so.
