RESEND: Inter-VM shared memory PCI device

resend for bug fix related to removal of irqfd

Support an inter-vm shared memory device that maps a shared-memory object as a
PCI device in the guest. This patch also supports interrupts between guest by
communicating over a unix domain socket. This patch applies to the qemu-kvm
repository.

-device ivshmem,size=&lt;size in format accepted by -m&gt;[,shm=&lt;shm name&gt;]

Interrupts are supported between multiple VMs by using a shared memory server
by using a chardev socket.

-device ivshmem,size=&lt;size in format accepted by -m&gt;[,shm=&lt;shm name&gt;]
           [,chardev=&lt;id&gt;][,msi=on][,ioeventfd=on][,vectors=n][,role=peer|master]
    -chardev socket,path=&lt;path&gt;,id=&lt;id&gt;

The shared memory server, sample programs and init scripts are in a git repo here:
