56e3f056e9 Tests for backtrace.c 
These need to be a separate executable, since the point of backtrace.c
is that it can crash and write stuff.

d631ddfb59 Make backtrace handler handle signals correctly. 
This meant moving a fair bit of code around, and writing a signal
cleanup function.  Still pretty nice from what I can tell, though.

2662885aa9 Use pc_from_ucontext.m4 from Google Performance Tools 
This M4 module lets us learn the right way (out of at least 18
possibilities) to extract the current PC for stack-trace-fixup-in-signal
purposes.  The Google Performance Tools license is 3-clause BSD.

ce8ae49c94 Improve new assertion message logging 
Don't report that a failure happened in the assertion_failed function just
because we logged it from there.

bd8ad674b9 Add a sighandler-safe logging mechanism 
We had accidentially grown two fake ones: one for backtrace.c, and one
for sandbox.c.  Let's do this properly instead.

Now, when we configure logs, we keep track of fds that should get told
about bad stuff happening from signal handlers.  There's another entry
point for these that avoids using non-signal-handler-safe functions.

063bea58bc Basic backtrace ability 
On platforms with the backtrace/backtrace_symbols_fd interface, Tor
can now dump stack traces on assertion failure.  By default, I log
them to DataDir/stack_dump and to stderr.

7a2b30fe16 Merge remote-tracking branch 'origin/maint-0.2.4' 
Conflicts:
	src/or/relay.c

Conflict changes were easy; compilation fixes required were using
using TOR_SIMPLEQ_FIRST to get head of cell queue.

59f50c80d4 Merge remote-tracking branch 'origin/maint-0.2.3' into maint-0.2.4 
Conflicts:
	src/or/or.h
	src/or/relay.c

Conflicts were simple to resolve.  More fixes were needed for
compilation, including: reinstating the tv_to_msec function, and renaming
*_conn_cells to *_chan_cells.

4aa9affec2 Fix test_cmdline_args to work with old openssl

between saying "no torrc found, using reasonable defaults" and
"configuration was valid".

1b8ceb83c9 Improved circuit queue out-of-memory handler 
Previously, when we ran low on memory, we'd close whichever circuits
had the most queued cells. Now, we close those that have the
*oldest* queued cells, on the theory that those are most responsible
for us running low on memory, and that those are the least likely to
actually drain on their own if we wait a little longer.

Based on analysis from a forthcoming paper by Jansen, Tschorsch,
Johnson, and Scheuermann. Fixes bug 9093.

5de88dda0a circuit_build_failed: distinguish "got DESTROY" case 
Roger spotted this on tor-dev in his comments on proposal 221.

We etect DESTROY vs everything else, since arma likes network
timeout indicating failure but not overload indicating failure.

0de71bf8eb Implement proposal 221: Stop sending CREATE_FAST 
This makes FastFirstHopPK an AUTOBOOL; makes the default "auto"; and
makes the behavior of "auto" be "look at the consensus."
