Implement /proc/PID/vm.
...
Refactored SyntheticFileSystem to maintain an arbitrary directory structure.
ProcFileSystem creates a directory entry in /proc for each new process.

Lots of hacking to make a very simple "ls" utility.
...
I added a dead-simple malloc that only allows allocations < 4096 bytes.
It just forwards the request to mmap() every time.
I also added simplified versions of opendir() and readdir().

Generalize the SpinLock and move it to AK.
...
Add a separate lock to protect the VFS. I think this might be a good idea.
I'm not sure it's a good approach though. I'll fiddle with it as I go along.
It's really fun to figure out all these things on my own.

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.

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