Zero out VirtualFileSystem::s_the in initializeGlobals().
...
This catches attempts to access the vfs before it's been constructed.

A lot of hacking:
...
- More work on funneling console output through Console.
- init() now breaks off into a separate task ASAP.
- ..this leaves the "colonel" task as a simple hlt idle loop.
- Mask all IRQs on startup (except IRQ2 for slave passthru)
- Fix underallocation bug in Task::allocateRegion().
- Remember how many times each Task has been scheduled.
The panel and scheduling banner are disabled until I get things
working nicely in the (brave) new Console world.

Add a way to initialize VFS globals.
...
This is needed since the kernel loader doesn't even zero out bss,
much less call any static constructors.

List the root directory after mounting /.
...
So cool that it works! It's spewing out a bunch of terminal escape sequences
that the OS console obviously doesn't support, but we'll get there too.

Rework DiskDevice's read() and write() to be non-virtual wrappers.
...
This way subclasses only have to implement readBlock() and writeBlock().
read() and write() require that the offset and length are both divisible
by the blockSize().

BlockDevice -> DiskDevice.
...
BlockDevice was the wrong name for this abstraction, since a block device
is a type of file in a unix system, and we should use that name for that
concept in the fs implementation.
