  rng-builtin: add an RNG backend that uses qemu_guest_getrandom()

Add a new RNG backend using QEMU builtin getrandom function.

It can be created and used with something like:

    ... -object rng-builtin,id=rng0 -device virtio-rng,rng=rng0 ...

  virtio-rng: Keep the default backend out of VirtIORNGConf

The default backend is only used within virtio_rng_device_realize().
Replace VirtIORNGConf member default_backend by a local variable.
Adjust its type to reduce conversions.

While there, pass &error_abort instead of NULL when failure would be a
programming error.

  virtio-pci: Add Function Level Reset support

Using FLR becomes convenient in cases where resetting the bus is
impractical, for example, when debugging the behavior of individual
functions.

  libvhost-user: fix SLAVE_SEND_FD handling

It doesn't look like this could possibly work properly since
VHOST_USER_PROTOCOL_F_SLAVE_SEND_FD is defined to 10, but the
dev->protocol_features has a bitmap. I suppose the peer this
was tested with also supported VHOST_USER_PROTOCOL_F_LOG_SHMFD,
in which case the test would always be false, but nevertheless
the code seems wrong.

Use has_feature() to fix this.

  libvhost-user: introduce and use vu_has_protocol_feature()

This simplifies the various has_feature() checks, we already
have vu_has_feature() but it checks features, not protocol
features.
