This was not noticed because:
- Logging is not covered in automated testing.

Originally crosvm calls VDA::reset() when either QueueClear the input

not guarantee if drop output buffers.
This CL removes the VDA::reset() call when QueueClear output queue.
Instead, we only clear the records of all the queued output buffers.
Note that it's still a workaround. The correct solution is to expose
VDA::DismissPictureBuffer() to libvda, and then clear the record of
the dismissed output buffer.

When VDA requests crosvm to allocate N output buffers, crosvm will
request the userspace to allocate N+1 output buffers. Then crosvm
keeps one output buffer for notifying EOS.
Originally, after the preserved buffer is dequeued to notify EOS,
crosvm might keep another output buffer for next EOS. If so, then
crosvm will register all the N+1 buffers to VDA.
This CL changes to fix the preserved buffer until VDA requests another
set of output buffers. Also, it introduces another variable to track
the resource ids of queued buffers.

This CL includes several smaller changes to how executors work:
* Replace BTreeMap with Slab, which should give us some small
performance benefits by giving O(1) lookups and reducing memory
allocations when adding new I/O operations. It also gives some
improvements to readability as we no longer have to carry around
"next_*" variables. Slab has no dependencies and we're already
pulling it in via the futures crate.
* WakerToken no longer implements Clone.
* Merge pending_ops and completed_ops in URingExecutor into a single
`ops` Slab and introduce an OpStatus enum that indicates whether an
operation is pending or completed. This also fixes a resource leak
where an operation that was canceled before completion would end up
staying in completed_ops ~forever. Add a test for this leak.
* Add a generation number to RingWakerState and include it in all
RegisteredSources. Since a RegisteredSource can outlive the
RingWakerState that created it, the generation number ensures that
it will only affect the RingWakerState that created it. Add a test
for this.
* Poison RegisteredSource so that it doesn't implement Send or Sync.
Since it's associated with a thread-local executor, sending it
across thread boundaries is not ok.

When switching to async usage of descriptor queues, it is more useful to
consume the offsets and lengths of the descriptor buffers instead of the
buffers mapped as `VolatileSlice`s. Having the offset,length pair and
the guest memory it refers to is enough to initiate async ops.
Async versions of non-offset read/write case aren't possible as using
the existing "seek" offset of the file doesn't make sense with async IO.
Adding the new version modifies the existing API. This is necessary as
now `Reader` and `Writer` own `GuestMemory`, which makes async possible.
TEST=unit tests and new test to exercise the async functions.

Use free + cached memory in the guest instead of available
reported through the balloon stats, which uses some strange heuristics,
for sizing the balloon. This brings it more in line to what
the ChromeOS available counter does.
Also, change the way the memory is balanced such that the
balloon is sized so that the "available" memory in the guest
would be equal the host's available memory.
