More paging stuff.
...
The test userspace process now runs at linear address 0x300000 which is
mapped to a dynamically allocated page from the MemoryManager. Cool!

A userspace process can now GPF and the OS goes on!
...
This is really rickety, but it kinda sorta works for my test GPF!

Allow running in QEMU with "./run q"
...
The kernel doesn't run in QEMU right now and I don't know why.

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.

Andreas Kling
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().

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.

Import the "gerbert" kernel I worked on earlier this year.

It's a lot crappier than I remembered it. It's gonna need a lot of work.

Move readEntireInode() up to FileSystem (from ext2.)

It's just a wrapper around multiple calls to readInodeBytes() now.
