Until we get a havok-source package built with new metadata-bearing autobuild,
the package name in autobuild.xml and CMake must agree with the tarball
filename.

This is an attempt to diagnose a generate_breakpad_symbols.py exception on a
Yosemite TC build host.

Build 296787 of 3p-update-curl includes the latest tip of 3p-curl.

The new TUT library build eliminates the ambiguity about ensure_equals(const
char*, ...) versus ensure_equals(const std::string&, ...). Now it's all based
on const std::string&. Remove pointless const char* overloads and ambiguous
forwarding templates.
With clang in Xcode 6, any new datatypes we intend to use with ensure_equals()
must have operator<<(std::ostream&, datatype) declared BEFORE lltut.h
#includes tut.hpp. Reorder code in certain test source files to guarantee that
visibility.

Update to build on Xcode 6.0 (fix unit tests): point to new version of GLUI that has been built to match viewer

Update to build on Xcode 6.0: point to new version of KDU libs with correct build configs that match viewer (and everything else)

Update to build on Xcode 6.0: Revert to non-hacked version of llphysicsextensions package now we can link

Update to build on Xcode 6.0: point to temporary, hacked version of llphysics_extensions that remove the unusd variables (and therefore warnings/errors) - see TODO list

Update to build on Xcode 6.0: point to new version of tut package that explicitly turns off unused function warnings vs. spreading the code throughout viewer
