For some strange reason, this was not needed with systemd v208.
But it's needed with systemd v215 on current Debian sid, and entirely
makes sense.

Stop modifying the value of our DirReqStatistics torrc option just
because we're not a bridge or relay. This bug was causing Tor
Browser users to write "DirReqStatistics 0" in their torrc files
as if they had chosen to change the config.

Fixes bug 4244; bugfix on 0.2.3.1-alpha.

Bugfix on ed8f020e; bug not in any
released version of Tor.  Found by Coverity; this is CID 1239290.

Fixes bug 11679; bugfix on 0.2.2.6-alpha

Patch from teor; ticket 13177.

Clients now send the correct address for their chosen rendezvous point
when trying to access a hidden service. They used to send the wrong
address, which would still work some of the time because they also
sent the identity digest of the rendezvous point, and if the hidden
service happened to try connecting to the rendezvous point from a relay
that already had a connection open to it, the relay would reuse that
connection. Now connections to hidden services should be more robust
and faster. Also, this bug meant that clients were leaking to the hidden
service whether they were on a little-endian (common) or big-endian (rare)
system, which for some users might have reduced their anonymity.

Fixes bug 13151; bugfix on 0.2.1.5-alpha.

Also, apply it.

These wrappers went into place when the default type for our unit
test functions changed from "void fn(void)" to "void fn(void *arg)".

To generate this patch, I did the same hokey-pokey as before with
replacing all operators used as macro arguments, then I ran a
coccinelle script, then I ran perl script to fix up everything that
used legacy_test_helper, then I manually removed the
legacy_test_helper functions, then I ran a final perl script to put
the operators back how they were.

This should get rid of most of the users of the old test_*
functions.  Some are in macros and will need manual cleanup, though.

This patch is for 13119, and was automatically generated with these
scripts.  The perl scripts are there because coccinelle hates
operators as macro arguments.

Fixes bug in c887e20e; bug in no released Tor version.

"At this point in the code, msg has been set to a string
constant. But the tor code checks that msg is not NULL, and the
redundant NULL check confuses the analyser[...] To avoid this
spurious warning, the patch initialises msg to NULL."

Patch from teor. another part of 13157.

"The NULL pointer warnings on the return value of
tor_addr_to_in6_addr32() are incorrect. But clang can't work this
out itself due to limited analysis depth. To teach the analyser that
the return value is safe to dereference, I applied tor_assert to the
return value."
