We shouldn't actually need this code nearly anywhere we build:
getdelim is POSIX, and mingw provides it.

We need to define this function when compiling with clang -m32 -ftrapv,
since otherwise we get link errors, since apparently some versions
of libclang_rt.builtins don't define a version of it that works? Or
clang doesn't know to look for it?

This definition is taken from the LLVM source at
  https://llvm.org/svn/llvm-project/compiler-rt/trunk/lib/builtins/mulodi4.c

I've also included the license (dual BSD-ish/MIT-ish).

This is taken verbatim from openssh 6.8p1, which appears to have
lightly tweaked it from the openbsd version.

Because in 95 years, we or our successors will surely care about
enforcing the BSD license terms on this code.  Right?

siphash is a hash function designed for producing hard-to-predict
64-bit outputs from short inputs and a 128-bit key.  It's chosen for
security and speed.

This M4 module lets us learn the right way (out of at least 18
possibilities) to extract the current PC for stack-trace-fixup-in-signal
purposes.  The Google Performance Tools license is 3-clause BSD.

There are as many divergent implementations of sys/queue.h as there
are operating systems shipping it, it would seem.  They have some code
in common, but have drifted apart, and have added other stuff named
differently.  So I'm taking a relatively sane one, and hoping for the
best.

I'm taking OpenBSD's in particular because of the lack of external
dependencies, the presence of a CIRCLEQ (we could use one of those in
places), and the liberal licensing terms.

I'm naming the file tor_queue.h, since historically we've run into
trouble having headers with the same names as system headers (log.h,
for example.)

when tor starts.
this breaks rpms and maybe other packages.

 At the start of the LICENSE and AUTHORS files, explain "LICENSE for what? AUTHORS of what?"  Apparently this has confused some people, who see our names in an AUTHORS file in a bundle, and so decide that we must be the go-to people tor tech support on the bundle.
