are visible in the guest at the directory /dev/virtio-ports.

implement function to hotplug character devices using as backend
unix sockets, binding a character device with a serial port allows
the communnication between processes running in the guest with
processes running in the host.

`getfd` receives a file descriptor via SCM rights and assign it a name,
this command is useful to send file descriptors from the host, and then
hot plug devices that needs file descriptors like vhost-vsock-pci devices.

`vhostfd` is used to specify the vhost-vsock device fd, and it holds
the context ID previously opened.
`disable-modern` is to disable the use of "modern" devices, by using virtio 0.9
instead of virtio 1.0. Particularly, this is useful when running the VM in a
nested environment.

`vhostfd` is the vhost file descriptor that holds the socket context ID
`disable-modern` prevents qemu from relying on fast MMIO

This commit enables staticcheck in the travis builds and fixes the existing
errors detected by staticcheck. There was one type of error repeated in
qemu.go in which the type of some constants was not explicitly specified.

We need to be able to specify the PCI slot for a bridge while
adding it.
Add test to verify bridge is correctly added.

This enable data-plane for scsi. All drives attached to the
scsi controller will have their IO processed in a single separate
IO thread instead of qemu's main event loop.

IOthreads also known as x-data-plane allow IO to
be processed in a separate thread rather than the main event
loop. This produces much better IO throughput and latency.

VSOCK sockets are added through a vhost PCI device.
It takes a device ID and a context ID, the latter being
the endpoint value to be reached from the host.

Introduce basic vhost-user-blk-pci support.
In adding this, cleaned up the QemuParams function to use a more
appropriate switch statement. Similarly, cleanup up the Valid() logic.
We still need to look into parameterization of the block parameter
fields as well as introducing multiqueue support for the vhost-user devices.

Some comments were network specific for vhost-user devices, which is
incorect. Fixed these.
Renamed the HWAddress field to be Address, so that it could potentially
be used more generically for non-network based vhost-user types.
