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.

Setup: tracer::start()

The main functionality is a tracer::trace_scope()! macro that will add

thread.

Finish: tracer::end() this will write the trace file (pretty printed

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).

5f4a6b42c0 qcow: Fix wrong alignment calculation

obviously wrong. Also, following what's done for 'round_down()', the
fixed code does not handle 'alignment == 0' explicitly.
