5bd2e7f606b726b598fdc26fe26a9b4029fab6d3 introduced queued_device_reqs
to accomodate devices that are not ready to receive messages until
they are activated in response to an event. But, devices that are
ready immediately were not added to the map.
When an event came in to one of these sockets (balloon and USB), the
socket file descriptor would be looked up in queued_device_reqs, and
crosvm would then crash because it wouldn't be found.
The correct behaviour, which this patch implements, is to treat a
missing entry the same as a Ready entry. An alternative would have
been to add all other sockets to queued_device_reqs, and set them to
Ready up front, but that would be more difficult to keep up to date
than having a default. This way, only devices that need queueing need
to be added to queued_device_reqs.

If a DiskCommand was received on the crosvm socket before the
virtio-block device was activated, the Token::VmRequest case in the
main event loop would forward the request to the block device socket,
and then wait syncronously for a response. That response would never
come because the device hadn't been activated, and it would never be
activated because the event loop would never continue, and therefore
never be able to respond to the event that causes the device to be
activated. crosvm would therefore just hang forever, waiting for a
response that would never come.
This patch fixes this deadlock by keeping track of whether devices
that send a response in this way have been activated yet. If they
have already been activated, messages are sent and responses are
received as normal. If they have not been activated, messages are
instead put into a per-device queue. Once the device is activated,
queued messages are processed all at once, and then the device is
marked as ready, and the queue is dropped. Future messages are
processed immediately as they come in, with no further queueing.
A device indicates that it is ready by sending a message on its
socket. The main crosvm event loop can then poll the socket, to be
notified when the device is ready. This poll event will only trigger
once -- once it has been received, it is removed from the poll
context.
Currently, the only device type that responds to external control
messages AND needs to be activated by an event is the block device.
The balloon device does not respond to messages, and the xhci
controller device is activated up front. The code is nevertheless
structured so that it should be very easy to drop another kind of
device in to the queuing system, should that be required.

This CL adds a fundamental part of the virtio video device, which will
be shared between the encoder and the decoder.
Both devices uses the virtio-video protocol proposed as RFC v3 [1,2].
The corresponding driver code is at CL:2060327 and its children CLs.
The actual decoding and encoding logic will be implemented in different
CLs.

Receiving no data can be considered a special case for MsgOnSocket. It
doesn't necessarily indicate EOF because usually messages are sent over
a datagram channel and some fixed sized messages are actually zero
sized. This change handles this by adding a specific result for
receiving no data when at least some was expected. This will also
simplify some error handling that had to unpack the `BadRecvSize`
variant.

Previously, writable pmem devices implemented the flush command using
fsync(); however, this does not guarantee synchronization of memory
mappings via mmap() to the file on disk. What we actually need is
msync() on the pmem file mapping, but we don't have access to that
mapping in the pmem child process, and it isn't trivial to pass it along
since it is owned by the Vm object once it has been added as a
mmap_arena.
In order to call msync() on the mapping, add a new VmControl socket so
that the pmem device can request that the main process issues an msync()
on the MemoryMappingArena identified by its slot number.

Poll available memory from the host and guest every second. Resize the
balloon so that available memory in the guest is the same as in the
host.
balancemem_timer adds a Token::BalanceMemory to poll_ctx every second
which creates a balloon stats request.
When the stats results come back from the guest, we compute how much the
balloon should change to balance available memory between the guest and
host. If this new balloon size is > 5% different than the current
balloon size, we make a BalloonControlCommand::Adjust to resize the
balloon.

In order to support 2 vq pairs for virtio-net, this patch create 2
sockets in one tap interface, 2 vq pairs(rx/tx) and 2 threads in
device model, So one vq pair has one thread and one socket in tap
corresponding.
On my SkyLake desktop with crosvm and ubuntu 18.04 guest:
If run one iperf server on host and one iperf client in guest, 2 vq
pairs has the same netwrok bandwidth as 1 vq pair, the bandwidth is
5.99Gbits/sec
If run two iperf server on host and two iperf client in guest,
In 1 vq pair mode, two iperf cliens bandwidth are 3.19Gbits/sec and
3.18Gbits/sec.
In 2 vq pairs mode, two iperf clients bandwidth are 4.87Gbits/sec and
4.86Gbits/sec.
So 2 vq pairs improve net bandwidth 52.7% compared with 1 vq pair in
this case.

current one container contains one group only, but one container could
contain multi groups actually. The main gap that current code to
support multi groups is that container will be initialized multi times
when multi groups exist, as each group will initialize container one time.
This patch extracts the code which should run one time only on a
container, so when the first group is added into container, this
container initialize code will run once. The container once initialize
code contains:
a. Set iommu driver type as VfioType1V2
b. Setup Iommu table on each guest memory region
c. create vfio_kvm device, so kernel kvm and vfio is associated.

Previously, all input events in CrosVM were required to be linux
input_events, which have a timestamp field that is actually unused by
when we send/receive from the guest which are of type
virtio_input_event. This CL allows CrosVM to understand both types of input
events in a first class manner. It is a follow up on
https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/1930405.
This CL also addresses some bugs with window driven input:
1. attach_event_device was being called before the surface was
created, so the devices were never attached.
2. The default touchpad size was not being set to the display window
size.
Additionally, it removes the unused event "filter" feature on event
sources.
Breaking change: from this point forward, CrosVM will treat input events sent
via a socket (e.g. SocketEventSource) to be virtio_input_events.

Change adds supports for providing pre-compiled bpf files as the policy
file for jailing. In short it's more effient to compile once on the
build machine than each time at runtime. Additionally libminijail's
support for more efficient bpfs (which use a binary tree instead of
a linear search) is currently only available via tools that are based
around pre-compiled use.
BUG=None
TEST=Ran build_test and verified that tests can pass with both bpf and
policy files (though the tests might only exercise the jail for the
plugin).

The Deref trait is usually only implemented by smart pointers or by
trivial wrappers around the underlying type. MsgSocket does not fit into
either category because it wraps a `UnixSeqPacket` to provide new
functionality. Having it implement can lead to confusing error messages,
especially for people who are new to rust and are not familiar with the
Deref trait and Deref coercion.
For example, calling `sock.send()` on a MsgSocket without first adding
`use msg_socket::MsgSender` leads to the compiler complaining about
mis-matched types for the `send` method. `UnixSeqPacket::send` expects a
`&[u8]` while `MsgSocket::send` expects a `&M`. The compiler also gives
no clues that it is implicitly coercing the socket to a `&UnixSeqPacket`
and using the `send` method from there.
Drop the `Deref` implementation. `MsgSocket` already implements
`AsRef<UniqSeqPacket>` so anything that _needs_ to access the underlying
`UnixSeqPacket` should just use that.

Adds a stub display that emulates a display without actually
displaying contents anywhere.
This is needed for transitioning Cuttlefish to always using minigbm
as its gralloc implementation. Cuttlefish currently uses a custom
gralloc and hwcomposer implementation when running without hardware
acceleration. The Cuttlefish team would like to start with removing
our custom gralloc implementation and use minigbm. For this, we need
to add a virtio 2D backend to crosvm. Our hwcomposer implementation
currenlly sends framebuffers from the guest to the host via sockets.
The gpu backend still requires a display so we need a stub display
to use with the 2D backend for the period of time while we are
either still using our hwcomposer implementation or until our
hwcomposer implementation is updated to use the virtio backend for
display.
