eabcab2b7c Count freed buffer bytes from buffers when oom-killing circuits. 
Also, aggressively clear the buffers to try to make their bytes go
away fast rather than waiting for the close-marked-connection code
to get 'em.

93c99508d2 Make header includes match declarations in pc_from_ucontext.m4 
With any luck, this will clean up errors where we detect that
REG_{EIP,RIP} is present in autoconf, but when we go to include it,
it isn't there.

adf2fa9b49 Fix compilation under openssl 0.9.8 
It's not nice to talk about NID_aes_{128,256}_{ctr,gcm} when they
don't exist.

Fix on 84458b79a78ea7e26820bf0; bug not in any released Tor.

bd25bda7c0 Remove 'struct timeval now' that was shadowing 'struct timeval now'. 
This was a mistake in the merge commit 7a2b30fe16. It
would have made the CellStatistics code give completely bogus
results. Bug not in any released Tor.

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.

ce8ae49c94 Improve new assertion message logging

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:

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:

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.

f6e07c158f Make the dir-key-crosscert element required 
In proposal 157, we added a cross-certification element for
directory authority certificates. We implemented it in
0.2.1.9-alpha.  All Tor directory authorities now generate it.
Here, as planned, make it required, so that we can finally close
proposal 157.

The biggest change in the code is in the unit test data, where some
old hardcoded certs that we made long ago have become no longer
valid and now need to be replaced.

4aa9affec2 Fix test_cmdline_args to work with old openssl 
If openssl was old, Tor would add a warning about its version in
between saying "no torrc found, using reasonable defaults" and
"configuration was valid".

532f70a807 Change documentation DirServer->DirAuthority 
We renamed the option, but we didn't actually fix it in the log
messages or the docs.  This patch does that.

For #10124.  Patch by sqrt2.

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.
