aee1155870 virtio-devices, vmm: Move to ExternalDmaMapping from vm-device 
Now that ExternalDmaMapping is defined in vm-device, let's use it from
there.

This commit also defines the function get_host_address_range() to move
away from the vfio-ioctls dependency.

c1be41bfbf net_util: Replace use of rand crate with libc::getrandom() 
The rand crate provides a full cross platform true cryptographic random
number implementation. As such it brings it lots of othe dependencies
and increases our binary size and compile time. This is excessive for
generating a MAC address.

│   │   │   ├── libc v0.2.86
│   │   │   ├── rand_chacha v0.3.0

4ed0e1a3c8 net_util: Simplify TX/RX queue handling 
The main idea behind this commit is to remove all the complexity
associated with TX/RX handling for virtio-net. By using writev() and
readv() syscalls, we could get rid of intermediate buffers for both
queues.

The complexity regarding the TAP registration has been simplified as
well. The RX queue is only processed when some data are ready to be
read from TAP. The event related to the RX queue getting more
descriptors only serves the purpose to register the TAP file if it's not
already.

With all these simplifications, the code is more readable but more
performant as well. We can see an improvement of 10% for a single
queue device.
