Originally, we clear all the output resources when getting
ProvidePictureBuffers command from VDA. At this point only VDA
discards the output buffers. crosvm should keep the output resources
until the output queue is cleared.
Note that at crrev.com/c/2494602, GAVDA will ignore the output buffers
after calling ProvidePictureBuffers(). So it's safe that crosvm passes
the output buffers after getting ProvidePictureBuffers command.

This disables the VIRTIO_RING_F_EVENT_IDX optimization, which seems to
be causing I/O to sometimes not complete when used with the Linux virtio

race/memory ordering issue when reading and updating the event index),
but disabling the feature flag is enough to get back to a reliable state
while the failure is debugged.
The particular test case that triggers this typically reproduces as a

This CL makes the following fundamental changes to cros_async:
1. Removes PollOrRing and replaces it with IoSourceExt, and the
subtraits ReadAsync & WriteAsync. The blanket implementation of
IoSourceExt has been dropped, and replaced with source specific
implementations of the trait. Those implementations are where
the code from PollOrRing has been moved.
2. Pinning for IoSource has been dropped from UringSource & the uring
futures. This appears to be safe because the IoSource doesn't contain
any self refs, or perform any operations beyond forwarding to the
RegisteredSource. (The FD is duped before being passed to
RingWakerState by RegisteredSource, so there doesn't seem to be any
data which would require pinning.)
3. U64Source was replaced by EventAsync.
It also switches all Error enums to use thiserror, which reduces
boilerplate.

to close the fd would trigger an assert. Note that because fds are

bitstream or output fds.

This allows code to create references to traits such as `&dyn Vcpu` for
`&dyn IrqChip`. This also allows keeping such traits inside of opaque
`Box` like wrappers.
To achieve this, trait methods referencing `Self` have an additonal
`where` clause that restricts them to sized types. Associated types are
removed and replaced with their trait equivalents (as parameters) or an
opaque Box (as return values).
To work around certain cases where a concrete type is needed, such as
for KVM based `IrqChip` impls, the `downcast_rs` trait is used to allow
`dynamic_cast` style casting.
The binary size impact of this change is small. For comparison, here is
the size change with this commit:

New option, --size-only, speeds up using build_test for getting release
binary size by skipping everything else. The lto flag is also added for
release builds to get a more realistic comparison.
The list of crates to test is built up automatically instead of
hard coded. To modify what gets included, empty .build_test_* files are
checked for existance. This is better than hard coding the list of
packages because it was frequently out of date.
For certain crate tests, a dynamic library that only exists in a sysroot
is required. This change includes a fix that adds the sysroot's lib
directory to the LD_LIBRARY_PATH env variable, similar to how
PKG_CONFIG_LIBDIR is modified.

There are no *at variants for the xattr syscalls so we were using the
path-based variants by reading the /proc/self/fd symlink. While this
symlink can track renames it cannot track if the user hard links the
file to some other location and then unlinks the original location. In
this case the symlink simply shows that the path was deleted even though
the fd is still valid.
To deal with this, stop using the path-based method. For regular files
and directories, we can simply open them and then make the appropriate
f{get,set,list,remove}xattr syscall. For non-regular files and
directories we can emulate an *at syscall by changing the CWD to /proc
and then making the path-based syscall via the self/fd path. Even
though the symlink is no longer valid, manipulating the fd via this path
still works.

This removes RunnableVcpu as an associated type on Vcpu traits, instead
using the new VcpuRunHandle type to enforce the same guarantees. This
simplifies implementations of Vcpu becuase only one impl is needed with
all the methods provided.
The other advantage to removing RunnableVcpu was that a Vcpu could be
try_cloned, defeating the purpose of consuming the Vcpu in the first
place with to_runnable. The type system and ownership model gave a false
sense of compile time safety. The usage of VcpuRunHandle is more
consistent with the fact that it is a runtime check that the programmer
is doing the safe thing. It's also consistent with all hypervisor impls.

Previously DataInit did not specify that any implementor `T` must not
contain implicit padding, though implementors of DataInit often include
a safety statement mentioning that they have no implicit padding. This
CL updates DataInit to clarify that any implementor must certify it has
no implicit padding to be safe / free of undefined behavior.

This is mostly a place holder that will be replaced if and when we
determine a complete plan for consuming crates from rust-vmm.

Originally we clear all the fields about both input and output
resource when either input or output queue gets ResourceDestroyAll
command.
In this CL, we handle this command for the input or output queue
separately.

At crrev.com/c/2416067 we split OutputResources out of Context struct.
Similiarly, this CL splits the fields that related to the input
resource to a dedicated struct `InputResources`.
Note that the field `res_id_to_res_handle` was shared by both input
and output resources. This CL split this field into both InputResources
and OutputResources struct.

At crrev.com/c/2416067 we split the fields that are related to output
resource from Context struct out to OutputResources struct. Also, we
move the methods that only interact with these fields to the
OutputResources's implementation. However, these methods are designed
from the aspect of Context struct, not OutputResources.
In this CL, we re-design the method of OutputResources to make the
interaction between Context and OutputResources more clear.

Some fields of the `Context` struct are related to the output
resources. These fields should be cleared together. This CL
consolidates these fields to another struct to make the code clear.
Note that we add `keep_resources` and `set_output_buffer_count` fields
into OutputResources struct. Originally these two fields are not
cleared with other fields together. So this CL is not just a refactor
CL, it changes the reset logic.

Previously, the VFIO code was using a single IRQ VM control socket
within an Arc<> container for both MSI and MSI-X; however, MsgSocket is
not technically Sync. In order to remove the Sync trait from MsgSocket,
split the MSI and MSI-X uses into two separate sockets and remove the
Arc wrapper.
