ba185e3eba Zero out VirtualFileSystem::s_the in initializeGlobals(). 
This catches attempts to access the vfs before it's been constructed.

79ffdb7205 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.

2d1d01661b 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.

705832f387 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.

8293a0ff36 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().

9cd0a34b5c 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.

9528edab92 Move readEntireInode() up to FileSystem (from ext2.) 
It's just a wrapper around multiple calls to readInodeBytes() now.

1f41a36c52 Add a Unix namespace for foo_t types. 
This allows me to keep prototyping things on a random desktop machine,
even if that machine has its own ideas about foo_t types.
