Some *_free functions threw asserts when passed NULL. Now all of them
accept NULL as input and perform no action when called that way.

This gains us consistence for our free functions, and allows some
code simplifications where an explicit null check is no longer necessary.

The file listing for excluded files was outdated. tree.h doesn't
exist anymore, and several other files were missing.

It turns out that OpenSSL 0.9.8m is likely to take a completely
different approach for reenabling renegotiation than OpenSSL 0.9.8l
did, so we need to work with both. :p   Fixes bug 1158.

Avoid crashing if the client is trying to upload many bytes and the
circuit gets torn down at the same time, or if the flip side
happens on the exit relay. Bugfix on 0.2.0.1-alpha; fixes bug 1150.

plus some other unrelated touchups that have been sitting in my
sandbox

New config option "CircuitStreamTimeout" to override our internal
timeout schedule for how many seconds until we detach a stream from
a circuit and try a new circuit. If your network is particularly
slow, you might want to set this to a number like 60.

aka Fix an instance where a Tor directory mirror might accidentally
log the IP address of a misbehaving Tor client. Bugfix on
0.1.0.1-rc.

shouldn't actually change anything, but who knows.

On this OSX version, there is a stub mlockall() function
that doesn't work, *and* the declaration for it is hidden by
an '#ifdef _P1003_1B_VISIBLE'.  This would make autoconf
successfully find the function, but our code fail to build
when no declaration was found.

This patch adds an additional test for the declaration.

Also, regenerate the detached-signature document whenever any signatures are
successfully added.

Allegedly echo -e is a bashism.  Remove it from debian/rules, we don't need it anyways (closes: #478631)

libssl 0.9.8k-6 disabled autorenegotation, and the -dev package
introduced the SSL3_FLAGS_ALLOW_UNSAFE_LEGACY_RENEGOTIATION flag.

Since we now set that flag if available we want to make sure that it
*is* available when building.

Therefore build-depend on libssl-dev >= 0.9.8k-6.

If we build against earlier versions we will not work once libssl gets
upgraded to a version that disabled renegotiations.

work with libssl that has renegotiation disabled by default.
