Remove workaround code for bug539
We fixed bug 539 (where directories would say "503" but send data
anyway) back in 0.2.0.16-alpha/0.1.2.19. Because most directory
versions were affected, we added workaround to make sure that we
examined the contents of 503-replies to make sure there wasn't any
data for them to find. But now that such routers are nonexistent,
we can remove this code. (Even if somebody fired up an 0.1.2.19
directory cache today, it would still be fine to ignore data in its
erroneous 503 replies.)

Fix some 'impossible' overflow bugs in byte counting
The first was genuinely impossible, I think: it could only happen
when the amount we read differed from the amount we wanted to read
by more than INT_MAX.
The second is just very unlikely: it would give incorrect results to
the controller if you somehow wrote or read more than 4GB on one
edge conn in one second. That one is a bugfix on 0.1.2.8-beta.

Look at the right errno when sending reason for connect() failure
In afe414 (tor-0.1.0.1-rc~173), when we moved to
connection_edge_end_errno(), we used it in handling errors from
connection_connect(). That's not so good, since by the time
connection_connect() returns, the socket is no longer set, and we're
supposed to be looking at the socket_errno return value from
connection_connect() instead. So do what we should've done, and
look at the socket_errno value that we get from connection_connect().

Remove superfluous -g -O2 compiler argument
Autoconf adds -g -O2 by default, so adding it ourselves is not required.
It also caused a warning with clang for every source file, so remove it
here. Fixes last issue of ticket 2696.

Consider sending stream-level SENDME cells on partial flushes.
Right now, we only consider sending stream-level SENDME cells when we
have completely flushed a connection_edge's outbuf, or when it sends
us a DATA cell. Neither of these is ideal for throughput.
This patch changes the behavior so we now call
connection_edge_consider_sending_sendme when we flush _some_ data from
an edge outbuf.

Use observed instead of declared uptime for HSDir
It is important to verify the uptime claim of a relay instead of just
trusting it, otherwise it becomes too easy to blackhole a specific
hidden service. rephist already has data available that we can use here.

Fix log message when we have too few dirauths
The calculation of when to send the logmessage was correct, but we

Disallow reject6 and accept6 lines in descriptors
This fixes a remotely triggerable assert on directory authorities, who
don't handle descriptors with ipv6 contents well yet. We will want to
revert this once we're ready to handle ipv6.

Avoid spurious bwhist parsing failures
This should fix a bug that special ran into, where if your state file
didn't record period maxima, it would never decide that it had
successfully parsed itself unless you got lucky with your
uninitialized-variable values.
This patch also tries to improve error messags in the case where a
maximum value legitimately doesn't parse.

Fix GETINFO config-text for private networks
In private networks, the defaults for some options are changed. This
means that in options_validate(), where we're testing that the defaults
are what we think they are, we fail. Use a workaround by setting a
hidden configuration option _UsingTestingTorNetwork when we have altered
the configuration this way, so that options_validate() can do the right
thing.
Fixes bug 2250, bugfix on 0.2.1.2-alpha (the version introducing private
network options).
