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().

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.

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.
