For running under SEV, we need to instruct virtio-mmio to use bounce
buffers through the DMA API, but there's currently no way of
signalling this using the device properties.
Force the use of the DMA API until there's a proper way to do this.

Bundle qboot (used as FW by libkrun-SEV) and initrd into the
library. To simplify the build process, we import then as binary blobs
into the project. Their source code can be found at the following
repositories:
- https://github.com/slp/qboot-krunfw
- https://github.com/slp/initrd-krunfw

Even if sk_shutdown == SHUTDOWN_MASK, allow processing of OP_RST
packets. This prevents RST storms caused by dangling sockets.
Also, rename previous patch files to homogenize them.

We don't really support restarting the conventional way, so ignore
"run_cmd" so we can fall back to an emergency sync and reboot.

If the socket already has another wrapped socket, don't create a new
one.
This fixes a bug where would break s2vi when userspace calls to listen()
on an already listening socket to change its attributes.
