Instead of synchronously waiting for balloon stat responses in the
control loop, add the balloon tube to the wait context and handle the
responses asynchronously. This allows us to get rid of the 100ms timeout
on stat requests, which in turn means we can get rid of the id field in
stat/wss messages because there are no longer "stale" requests.
The fact that balloon stat requests will no longer timeout may require
that clients handle timeouts themselves, instead of relying on a
hardcoded timeout in the crosvm implementation. This adds a new function
to crosvm_control to allow getting the balloon stats with a timeout.

Truncating a large file can result in a significant amount of IO for
updating the filesystem metadata. When swap is disabled because an app
is being launched, this IO ends up competing with the IO needed to
launch the app, resulting in significant latency.
When disabling swap because of an app launch, cleaning up the swap file
is not high priority. However, when disabling swap because of low disk
space, the swap file needs to be cleaned up immediately. As such, make
the slow cleanup of the swap file an extra parameter to disabling swap.

devices can still be running and potentially modifying the env (filling
up buffers, modifying variables). The aim of this CL is to put the
devices to sleep when the VM is put in suspended mode, and to wake the
devices when the VM goes back to resumed mode.
Added new flag to `suspend` and `resume` commands: `--full`
which does a full VM suspend.
Added new VmRequest: SuspendVm, ResumeVm.

for ease of initial implementation the number of WSS bins was hard-coded
to 4, however the WSS spec and kernel driver permit any number of bins
between 2-16. this patchset introduces a crosvm run flag which allows to
override the default 4 bins.
the protobuf-encoded WSS report will scale the number of bins correctly
in the return value, however the C crosvm_control_* API will always use
an array of 16 buckets, with a `num_bins` parameter that indicates how
many of them are actually valid. this has been done to preserve safety
across the ffi boundary.
this patchset also removes the sending of an initial WSS config. the
coordinating program (e.g. concierge et al.) is responsible for sending
the config to the guest after boot via the crosvm_control_* API. this is
largely due to the fact there may be various desirable configs for
varying scenarios and it does not make sense to have a baked-in default
config anymore.
