df6bd478ee Implement the client side of proposal 198
This is a feature removal: we no longer fake any ciphersuite other
than the not-really-standard SSL_RSA_FIPS_WITH_3DES_EDE_CBC_SHA
(0xfeff).  This change will let servers rely on our actually
supporting what we claim to support, and thereby let Tor migrate to
better TLS ciphersuites.

As a drawback, Tor instances that use old openssl versions and
openssl builds with ciphers disabled will no longer give the
"firefox" cipher list.

your openssl/sed/sha1sum happened to live in a directory with a space in

7363eae13c Use the EVENT_BASE_FLAG_NOLOCK flag to prevent socketpair() invocation
In Tor 0.2.2, we never need the event base to be notifiable, since we
don't call it from other threads.  This is a workaround for bug 4457,
which is not actually a Tor bug IMO.

e1c6431e42 Correct the handling of overflow behavior in smartlist_ensure_capacity
The old behavior was susceptible to the compiler optimizing out our
assertion check, *and* could still overflow size_t on 32-bit systems
even when it did work.

3a890b3b70 Properly refcount client_identity_key
In a2bb0bf we started using a separate client identity key. When we are
in "public server mode" (that means not a bridge) we will use the same
key. Reusing the key without doing the proper refcounting leads to a
segfault on cleanup during shutdown. Fix that.

Also introduce an assert that triggers if our refcount falls below 0.
That should never happen.

c5a3664f27 Fix zlib macro brokenness on osx with zlib 1.2.4 and higher.
From the code:
   zlib 1.2.4 and 1.2.5 do some "clever" things with macros.  Instead of
   saying "(defined(FOO) ? FOO : 0)" they like to say "FOO-0", on the theory
   that nobody will care if the compile outputs a no-such-identifier warning.

   Sorry, but we like -Werror over here, so I guess we need to define these.
   I hope that zlib 1.2.6 doesn't break these too.

Possible fix for bug 1526.

1ba90ab655 Fix a potentially useless integer overflow check.
GCC 4.2 and maybe other compilers optimize away unsigned integer
overflow checks of the form (foo + bar < foo), for all bar.

Fix one such check in `src/common/OpenBSD_malloc_Linux.c'.

718252b253 Check return value in fmt_addr
Previously, if tor_addr_to_str() returned NULL, we would reuse the
last value returned by fmt_addr().  (This could happen if we were
erroneously asked to format an AF_UNSPEC address.)  Now instead we
return "???".
