Alice Frosi e4892e3396 qemu/qmp: preparation for s390x support
This PR prepares for the s390x support. It introduces:
 - a generalization of ccw and pci devices. The variables for the pci devices
   have been renamed by removing the Pci suffix. They have been moved to the
   qemu_arch_base.go
 - the mapping isVirtioPCI has been move to qemu_arch_base.go because in
   this way a different mapping can be added for other architecture (e.g
   s390x)
 - the functions QemuNetdevParam and QemuDeviceParam have been moved to
   qemu_arch_base.go. In this way, they could be reimplemented for other
   architecture for the case VHOSTUSER
 - a function disableModern has been introduced to check if the device is
   a pci device and then returns the right parameters. In the case of ccw
   devices, they don't have the disable-modern flag
 - a function mqParameter has been introduced to return the right
   parameters for the mq case. The virtio-net-ccw device doesn't have the
   vectors flag
 - in qemu_arch_base_test.go contains the test and strings that can be
   overwritten for other architectures (e.g s390). The devices names and
   the flags for the devices can be overwritten.
 - the string for the romfile has been replaced by a variable romfile
   that could be left empty if the devices doesn't support a romfile as
   for the ccw devices for s390.
 - clean-up: the disable-modern=on/off options have been changed to
   disable-modern=true/false. In the code there was a mixture of on/true
   off/false

Fixes: #61

Virtual Machine Manager for Go

Go Report Card Build Status GoDoc Coverage Status

Virtual Machine Manager for Go (govmm) is a suite of packages that provide Go APIs for creating and managing virtual machines. There's currently support for only one hypervisor, qemu/kvm, support for which is provided by the github.com/intel/govmm/qemu package.

The qemu package provides APIs for launching qemu instances and for managing those instances via QMP, once launched. VM instances can be stopped, have devices attached to them and monitored for events via the qemu APIs.

The qemu package has no external dependencies apart from the Go standard library and so is nice and easy to vendor inside other projects.
