This patch implement HECI virtualization backend service based on virtio
userspace framework. This service introduce a virtio-heci device model
for DM, and can be enabled by DM parameter '-s [BUS NO],virtio-heci'.
The HECI virtualization need both backend service in device-model and
frontend driver in guest to work. Backend service mainly emulates HECI
device's behaviors to satisfy frontend driver. They are based on virtio
userspace framework. Currently, it is using two virtqueues, one is for
TX and another is for RX.

problems by adhering to the strict anti-aliasing rules and also
initializing the 'tfd' variable where the compile believed it
_could_ be used uninitialized.

The acrnctl can help user to create, delete, launch and stop UOSs,
To see what it can do, just run:
# acrnctl
or
# acrnctl help
you may see:
support:
list
start
stop
del
add
Use acrnctl [cmd] help for details
There are examples:
(1) add a VM
Each time you can just add one VM. Suppose you have an UOS
launch script, such as launch_UOS.sh
you can run:
# acrnctl add launch_UOS.sh -U 1
vm1-14:59:30 added
Note that, launch script shoud be able to launch ONE UOS. If
it fail, it is better to print some error logs, to tell user
the reason, so that he knows how to solve it.
The vmname is important, the acrnctl searchs VMs by their
names. so duplicated VM names are not allowed. Beside, if the
launch script changes VM name at launch time, acrnctl will
not recgonize it.
(2) delete VMs
# acrnctl del vm1-14:59:30
(3) show VMs
# acrnctl list
vm1-14:59:30 untracked
vm-yocto stop
vm-android stop
(4) start VM
you can start a vm with 'stop' status, each time can start
one VM.
# acrnctl start vm-yocto
(5) stop VM
you can stop VMs, if their status is not 'stop'
# acrnctl stop vm-yocto vm1-14:59:30 vm-android

2. Send the appropriate PCI interrupt for the device.
* If MSI-X capability is enabled:
1. If config_msix_vector is not NO_VECTOR, request the appropriate
MSI-X interrupt message for the device, config_msix_vector sets
