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.

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

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.
