port virtio_disk to virtio spec 1.0+
...
The legacy interface is confusing. It's better to make virtio_disk
conform to the virtio spec. This is supported in QEMU since 4.2 by
disabling force-legacy for virtio-mmio.

Assert that the size in mappages() is always positive
...
If va % PGSIZE == 0 and size == 0, we have last < a at the start of
the loop so we might never terminate. That being said, this
particular case couldn't be triggered for now.

Rename icache to itable
...
The inode cache isn't really a cache. The main purpose of it is to
allow for synchronization (locking individual inodes), providing
long-lived references to inodes, and ensuring that there is only inode
in memory.
