4fea40f008 fuzz: Balloon: Reduce the guest memory size and queue size 
With the guest memory size of 1MB, a valid descriptor size can be close
to the guest memory size (e.g. 1MB) and can contain close to 256k
valid pfn entries (each entry is 4 bytes). Multiplying the queue
size (e.g. 256), there can be close to 64 millions pfn entries to
process in a single request. This is why the oss-fuzz reported a
timeout (with a limit of 60s).

By reducing the guest memory size and the queue size, the worst-case now
is 8 million pfn entries for fuzzing, which can be finished in around 20
seconds according to my local experiment.

Also added a `simple_api_full_command()` to avoid having to specify the

ef603fde4c fuzz: Reduce the guest memory size for balloon fuzzer 
As the virt queues are initialized with random bytes from the fuzzing
engine, a descriptor buffer for the available ring can have a very large
length (e.g. up to 4GB). This means there can be up to 1 billion
entries (e.g. page frame number) for virtio-balloon to process a signal
available descriptor (given each entry is 4 bytes). This is the reason
why oss-fuzz reported a hanging issue for this fuzzer, where the
generated descriptor buffer length is 4,278,321,152.

We can avoid this kind of long execution by reducing the size of guest
memory. For example, with 1MB of guest memory, the number of descriptor
entries for processing is limited ~256K.

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.
