Driver testing enhancement: Making so that you can write shitty drivers in your testing unikernel Minor refactoring: Moving defines from source to header files
Modern Virtio (>=1.0) implementation needed for VirtioFS. Split Virtio queues were implemented because the VirtioFS device does not support packed. This is a feature enhancement. The Virtio plane is designed with the possibility of this being implemented in the future.
Testing the following: 1) Enqueue of an entire buffer chain 2) Multiple buffer chains in flight 3) Stress testing with many chains and kicks 4) Testing interrupt and callback
Tests revived: posix/integration/file_fd fs/integration/memdisk fs/integration/fat32 fs/integration/vfs Requires diskbuilder to work. Please accept diskbuilder PR.
VirtioFS: 1) VirtioFS driver together with FUSE structs 2) Test for demonstrating read and write functionality VirtioPMEM: 1) VirtioPMEM driver 2) Copied test from fat32 that uses PMEM as memdisk Dependencies are diskbuilder and vmrunner.

This is an oversized PR that will be reposted (most likely). Meant mostly for later discussion.
Dependencies: Vmrunner and diskbuilder (reviving several old file system tests and test for VirtioPMEM).
Consists of:
Uses a Virtio console device for testing.
The VirtioPMEM test demonstrates this.
