This is the mega-ucontext commit. It replaces the task switching mechanism with a new one inspired by ucontext. It works under Linux, OS X and Windows, and is Valgrind clean on Linux and OS X (provided the runtime is built with gcc).
This commit also moves yield and join to the standard library, as requested in #42. Join is currently a no-op though.

Added lock_and_signal::signal_all(), and made the rust_kernel::join() use wait instead of yield.

Tidy up the sync dir, remove dead or mis-designed code in favour of OS primitives, switch rust_kernel to use a lock/signal pair and wait rather than spin.

Lots of design changes around proxies and message passing. Made it so that domains can only talk to other domains via handles, and with the help of the rust_kernel.

Added a few utility classes, cleaned up the include order of .h files, and started to make the Rust kernel own domain message queues rather than the Rust domains themselves.

Implemented an lock free queue based on this paper http://www.cs.rochester.edu/~scott/papers/1996_PODC_queues.pdf, the "lock free queue" we had before wasn't lock free at all.

Putting out the burning tree on Windows. Turns out you can completely starve threads by not yielding on windows/vmware, really weird.

Added a message passing system based on lock free queues for inter-thread communication. Channels now buffer on the sending side, and no longer require blocking when sending. Lots of other refactoring and bug fixes.
