Each device does not know whether it is a multi-function device when it
is created; this is only possible to determine once all devices have
been added to the PCI bus. Change the PCI root code to check for this
and update the multi-function bit dynamically at runtime.
The multifunction option for the stub PCI device is also removed; it
will be determined automatically, so there is no need for the user to
specify it.

This CL makes the builder wait until we got at least 5 commits to

not matter much.

store the command into a set of pending commands, but when doing so we

For bridge's memroy and prefetch memory window, current the limit is
smaller than the base, this means pcie rp doesn't support this window,
but OS still allocates 2M memroy window and 2M prefetch memory window
for it, this has two problems:
a. kernel allocates mmio, but crosvm's system allocator doesn't capture
this allocation and crosvm still use system allocator to allocate mmio
for hotplug in device, so it may have conflict between kernel and crosvm.
b. the 2MB window is too small, as the added device behind this bridge
is allocated mmio from this window by kernel, if device required mmio
is large than 2MB, the device couldn't work.
This commit preallocates 8MB memory window and 64MB prefetch memory window
for one pcie rp, and let kernel allocate mmio for its children devices
from this window, kernel also maintains the allocation and free of this
window, crosvm system allocator doesn't care about which device own the
segment of this window.

Currently the crosvm encoder device only supports single-buffer frames,
yet the encoder requires as many buffers to be submitted as there are
component planes in the frame (e.g. 2 for NV12).
This is incorrect and in effect the encoder ignores all but the first
plane, but nonetheless it expects the number of submitted buffers to be
equal to the number of component planes. This makes it impossible to fix
the issue at the kernel level using http://crrev.com/c/3358090.
Change the expectation about the number of buffers to support both
single-planar and multi-planar submissions. That way we won't break the
encoder while fixing the problem on the guest side.

In ARCVM `genfs_contexts`, we have hard-coded rules with device node id for
network and virtio-gpu. In crosvm virtio devices creation, the
device node id is assigned by order, so introducing 2 virtio-snd devices
will shift id to id+2 for those devices created after virtio-snd.
This will break ARCVM-next boot.
Changes:
Move virtio-snd device creation after virtio GPU.

This fixes a bug introduced by [1] when removing vfio device and
'device_num' is zero.
A panic occured when unplug a vfio device:
[ERROR:src/panic_hook.rs:90] thread 'crosvm_vcpu4' panicked at 'attempt to subtract with overflow', devices/src/vfio.rs:462:9
The variable group.device_num is 0 when subtract. And when initalizes a
