Barrelfish snapshot release

This release is a snapshot of the main Barrelfish source tree as of 2009-12-19. Highlights of this release include:

• Hake, our new (home-grown) build system. As well as fixing a lot of annoyances we had with CMake, this allows us to build binaries for multiple architectures concurrently in the same build tree. For details, see doc/Hake.tex in the source tree.
• A new event tracing framework and visualisation tool (Aquarium), as demonstrated in the poster session at SOSP'09. For details on running this, see tools/demo/guide.pdf in the source tree.
• The Filet-o-Fish (FoF) framework for domain-specific languages, and two DSLs, Fugu and Hamlet, using it in Barrelfish. Further details can be found in the FoF paper from PLOS'09 and in Pierre-Evariste Dagand's Masters Thesis.
• VMkit, an x86_64 virtual machine monitor for Barrelfish, using the AMD SVM hardware extensions (with nested paging support). Futher details are in Raffaele Sandrini's Masters Thesis.
• The USB driver stack described in Animesh Trivedi's Masters Thesis.
• Initial (incomplete) ports to ARM, x86_32 and Beehive architectures. We do not expect these to be usable by anyone yet.
• A more usable shell.
• The APIC interrupt model is now used exclusively (including IOAPICs), allowing drivers to run on any core and have their interrupts routed correctly.

For more general information, please see the FAQ.
