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.

Lots of hacking:
...
- Turn Keyboard into a CharacterDevice (85,1) at /dev/keyboard.
- Implement MM::unmapRegionsForTask() and MM::unmapRegion()
- Save SS correctly on interrupt.
- Add a simple Spawn syscall for launching another process.
- Move a bunch of IO syscall debug output behind DEBUG_IO.
- Have ASSERT do a "cli" immediately when failing.
This makes the output look proper every time.
- Implement a bunch of syscalls in LibC.
- Add a simple shell ("sh"). All it can do now is read a line
of text from /dev/keyboard and then try launching the specified
executable by calling spawn().
There are definitely bugs in here, but we're moving on forward.

Launching an arbitrary ELF executable from disk works! :^)
...
This is so cool! It's a bit messy now with two Task constructors,
but eventually they should fold into a single constructor somehow.

Oops, StringImpl's "the empty string" global was not always initialized.

These "oops forgot to initialize" bugs are getting annoying...
