Annotated Virtio-Net feature bits supported by Qemu, added feature bits added to virtio more recently.
Updated copyright notice in Info.plist and startup console message.
Specifically build against OSX 10.8 SDK, not latest. This will produce builds that work on 10.7+.

I'm going to try and set up a build system for creating builds for older systems.
Bugfix: When destroying interrupt handler, disable it first.
Fixed logic error when enabling network interface without debugger started.
Only enable interrupt handler when the main ethernet interface is enabled.

The debugger client doesn't need the interrupt handler.
Fixed shutdown ordering. Make sure the ethernet interface and debugger clients are detached by the time the driver shuts down, and interrupts are no longer firing or being handled when we clear the DMA buffers.
Bugfix: avoid stomping on packet header buffer memory when freeing it on shutdown.

This fixes the panic that occurred when unloading the kext while running the kernel with -zp -zc and thus a timing-dependent kernel memory corruption otherwise. This makes the kext fully unloadable at runtime.
Speed up the kernel debugger by initially waiting less in polled send.
License change: now using LGPLv3.
New 0.9.4 release, including installer binary!
