Add more explanation in doc/HACKING about how to read gcov output,
including a reference to the gcov documentation in the GCC manual.
Also add details about how our postprocessing scripts modify gcov
output.
When we added HTTPTunnelPort, the answer that we give when you try
to use your SOCKSPort as an HTTP proxy became wrong. Now we explain
that Tor sorta _is_ an HTTP proxy, but a SOCKSPort isn't.
I have left the status line the same, in case anything is depending
on it. I have removed the extra padding for Internet Explorer,
since the message is well over 512 bytes without it.
Fixes bug 23678; bugfix on 0.3.2.1-alpha.
Because our monotonic time interface doesn't play well with value set to 0,
always initialize to now() the scheduler_last_run at init() of the KIST
scheduler.

When a channel is scheduled and flush cells returns 0 that is no cells to
flush, we flag it back in waiting for cells so it doesn't get stuck in a
possible infinite loop.
It has been observed on moria1 where a closed channel end up in the scheduler
where the flush process returned 0 cells but it was ultimately kept in the
scheduling loop forever. We suspect that this is due to a more deeper problem
in tor where the channel_more_to_flush() is actually looking at the wrong
queue and was returning 1 for an empty channel thus putting the channel in the
"Case 4" of the scheduler which is to go back in pending state thus
re-considered at the next iteration.
This is a fix that allows the KIST scheduler to recover properly from a not
entirelly diagnosed problem in tor.

When we added single_conn_free_bytes(), we cleared the outbuf on a
connection without setting outbuf_flushlen() to 0. This could cause
an assertion failure later on in flush_buf().
Fixes bug 23690; bugfix on 0.2.6.1-alpha.
This caused a BUG log when we noticed that the circuit had no
channel. The likeliest culprit for exposing that behavior is
d769cab3e5, where we made circuit_mark_for_close() NULL out
the n_chan and p_chan fields of the circuit.
Fixes bug 8185; bugfix on 0.2.5.4-alpha, I think.
My current theory is that this is just a marked circuit that hasn't
closed yet, but let's gather more information in case that theory is
wrong.
Diagnostic for 8185.
This patch ensures that we return TOR_COMPRESS_BUFFER_FULL in case we
have a input bytes left to process, but are out of output buffer or in
case we need to finish where the compression implementation might need
to write an epilogue.

The clock_skew_warning() refactoring allowed calls from
or_state_load() to control_event_bootstrap_problem() to occur prior
bootstrap phase 0, causing an assertion failure. Initialize the
bootstrap status prior to calling clock_skew_warning() from
or_state_load().
or_state_load() was using an incorrect sign convention when calling
clock_skew_warning() to warn about state file clock skew. This caused
the wording of the warning to be incorrect about the direction of the
skew.
Previously we would detect the system openssl on OSX, and then fail
to use it, since we required Open 1.0.1 or later. That's silly!
Instead of looking for RAND_add(), look for TLSv1_1_method(): it was
introduced in 1.0.1, and is also present in LibreSSL.
Also, add the hombebrew path to our search path here.
Fixes bug 23602; bugfix on 0.2.7.2-alpha.
Authority IPv6 addresses were originally added in 0.2.8.1-alpha.
This leaves 3/8 directory authorities with IPv6 addresses, but there
are also 52 fallback directory mirrors with IPv6 addresses.
Resolves 19760.
RENDEZVOUS1 cell is 84 bytes long in v3 and 168 bytes long in v2 so this
commit pads with random bytes the v3 cells up to 168 bytes so they all look
alike at the rendezvous point.

This warning is caused by a different tv_usec data type on macOS
compared to the system on which the patch was developed.
Fixes 23575 on 0.3.2.1-alpha.
