kvm tools: Introduce generic I/O thread pool

This patch adds a generic pool to create a common interface for working with
threads within the kvm tool. Main idea here is using this threadpool for all
I/O threads instead of having every I/O module write it's own thread code. The
process of working with the thread pool is supposed to be very simple.

During initialization, each module which is interested in working with the
threadpool will call threadpool__add_jobtype with the callback function and a
void* parameter. For example, virtio modules will register every virt_queue as
a new job type. During operation, When theres work to do for a specific job,
the module will signal it to the queue and would expect the callback to be
called with proper parameters. It is assured that the callback will be called
once for every signal action and each callback will be called only once at a
time (i.e. callback functions themselves don't need to handle threading).

This change was recommended by Ingo Molnar in his reply to mail 'Use the root

explicitly run the 'kvm run --help' command, in case the kvm tool could not find
a default kernel image to boot.

kvm tools: Implement virtio network device

This patch implement virtio network device.
Use '-n virtio or --network=virtio' to enable it.

The current implementation uses tap which needs root privileges to create a
virtual network device (tap0) on host side. Actually, what we need is
CAP_NET_ADMIN.

The host side tap0 is set to 192.168.33.2/24.
You need to configure the guest side eth0 to any ip address in
192.168.33.0/24.

Here are some scp performance test for differenct implementations:
None of rx and tx as thread:
guest to host 3.2MB/s
host to guest 3.1MB/s

Only rx as thread:
guest to host 14.7MB/s
host to guest 33.4MB/s

Both rx and tx as thread(This patch works this way):
guest to host 19.8MB/s
host to guest 32.5MB/s
