194b59f44b fuzz: Don't overload meaning of reset()
This function is for really for the transport layer to trigger a device
reset. Instead name it appropriately for the fuzzing specific use case.

b35e6f3018 tracing: Tracing infrastructure
Add a new feature "tracing" that enables tracing functionality via the
"tracer" crate (sadly features and crates cannot share the same name.)

Setup: tracer::start()

The main functionality is a tracer::trace_scope()! macro that will add
trace points for the duration of the scope. Tracing events are per
thread.

Finish: tracer::end() this will write the trace file (pretty printed
JSON) to a file in the current directory.

76dbf85b79 net: Give the user the ability to set MTU
Add a new "mtu" parameter to the NetConfig structure and therefore to
the --net option. This allows Cloud Hypervisor's users to define the
Maximum Transmission Unit (MTU) they want to use for the network
interface that they create.

In details, there are two main aspects. On the one hand, the TAP
interface is created with the proper MTU if it is provided. And on the
other hand the guest is made aware of the MTU through the VIRTIO
configuration. That means the MTU is properly set on both the TAP on the
host and the network interface in the guest.

f38056fc9e virtio-devices, vmm: Simplify virtio-mem resize operation
There's no need to delegate the resize operation to the virtio-mem
thread. This can come directly from the vmm thread which will use the
Mem object to update the VIRTIO configuration and trigger the interrupt
for the guest to be notified.

In order to achieve what's described above, the VirtioMemZone structure
now has a handle onto the Mem object directly. This avoids the need for
intermediate Resize and ResizeSender structures.

e1b483fc88 fuzz: Add fuzzer for virtio-rng
To make the fuzzer faster and more effective, the guest memory is
setup with a much smaller size (comparing with other virtio device
fuzzers) and  a hole between the memory for holding virtio queue and
the rest of guest data. It brings two benefits: 1) avoid writing large
chunk of data from 'urandom' into the available descriptor chain (which
makes the fuzzer faster); 2) reduce substantial amount of overwrites to
the virtio queue data by the data from 'urandom (which makes the fuzzer
more deterministic and hence effective).

43c4270289 rpm: doc: Remove bundled SPEC and update README
Packages targeting various distributions are now available thanks to the
Open Bulid Service. The SPECS have been moved to a separate repo under

https://github.com/cloud-hypervisor/obs-packaging

which documents how to include pre-compiled binaires in a supported
distribution. Besides the Cloud Hypervisor itself, accompanying pieces
like UEFI bins are available, too.

Any contributions to the packaging can be also accepted in
the aforementioned repo. Further integration with the OBS like PR
validation is to be targeted there, too, as far as it can get. As the
packaging topic has moved in a separate repo, the bundled SPEC became
obsolete is suggested for removal.

Fixes: #4257
