This adds a new disk file type next to raw files and qcow images that
represent an indirection to further raw disk files. The disk file
itself is a proto file with references to file paths for other disks to
open and their virtual offsets and lengths.
The intention is to make it easy to assemble a single virtual hard disk
out of several distinct partition files. In the particular case of
Cuttlefish running Android in a VM, this is relevant as the Android
build system distributes partitions as separate raw files. While the
simple solution is to pass each partition as a separate raw disk, some
functionality (like the bootloader) assumes there is a partition table
with multiple distinct partitions on a single disk.
Implementing composite disk support in the VMM bridges this gap through
supporting the general-purpose case of a disk built out of multiple
component files.
If desired, this can be extended to support qcow files to support
unusual configurations like a mixed qcow/raw disk.
Enabled with the "composite-disk" feature.

This manifested itself in a couple places that were turning shared
memory buffers into slices for the purposes of passing these slices to
`Read` and `Write` trait methods.
However, this required the removal of the methods that took `Read` and
`Write` instances. This was a convenient interface but impossible to
implement safely because making slices from raw pointers without
enforcing safety guarantees causes undefined behaviour in Rust. It turns
out lots of code in crosvm was using these interfaces indirectly, which
explains why this CL touches so much.

- In vhost where the original code allocates a Vec<u8> with 1-byte
alignment and casts the Vec's data pointer to a &mut vhost_memory
which is required to be 8-byte aligned. Underaligned references of
type &T or &mut T are always undefined behavior in Rust.
- Same pattern in x86_64.
- Same pattern in plugin::vcpu.
- Code in crosvm_plugin that dereferences a potentially underaligned

The newer protobuf version depends on the tempfile crate rather than
tempdir, the latter being now deprecated. So I replaced our immitation
tempdir crate with one that matches the API of tempfile instead. As a
reminder, we use this crate as a patch to avoid pulling in all of the
rand crate and its many dependencies.

The Ac97 device provides the guest with an audio playback device. All

The device is emulated by `Ac97Dev` which interfaces with the PCI bus.
`Ac97Dev` uses `Ac97` to drive audio functions and emulate the device
registers. Physical Ac97 devices consist of two parts, the bus master
and a mixer. These two sets of registers are emulated by the

`Ac97BusMaster` handles audio samples and uses `Ac97Mixer` to determine

This CL adds a crate `sync` containing a type sync::Mutex which wraps
the standard library Mutex and mirrors the same methods, except that
they panic where the standard library would return a PoisonError. This
API codifies our error handling strategy around poisoned mutexes in
crosvm.
- Crosvm releases are built with panic=abort so poisoning never occurs.
A panic while a mutex is held (or ever) takes down the entire process.
Thus we would like for code not to have to consider the possibility of
poison.
- We could ask developers to always write `.lock().unwrap()` on a
standard library mutex. However, we would like to stigmatize the use
of unwrap. It is confusing to permit unwrap but only on mutex lock
results. During code review it may not always be obvious whether a
particular unwrap is unwrapping a mutex lock result or a different
error that should be handled in a more principled way.
Developers should feel free to use sync::Mutex anywhere in crosvm that
they would otherwise be using std::sync::Mutex.

The Scm object was made to reduce the number of heap allocations in
the hot paths of poll loops, at the cost of some code complexity. As it
turns out, the number of file descriptors being sent or received is
usually just one or limited to a fixed amount that can easily be covered
with a fixed size stack allocated buffer.
This change implements that solution, with heap allocation as a backup
in the rare case that many file descriptors must be sent or received.
This change also moves the msg and cmsg manipulation code out of C and
into pure Rust. The move was necessary to allocate the correct amount
of buffer space at compile time. It also improves safety by reducing the
scope of unsafe code. Deleting the code for building the C library is
also a nice bonus.
Finally, the removal of the commonly used Scm struct required
transitioning existing usage to the ScmSocket trait based methods. This
includes all those changes.

Note passing this cpuid info itself is not sufficient unless
CPU vendor is something Linux kernel recognizes. Therefore, I am
removing cute spoofing of the vendor id, allowing host value to
pass through.
I believe it is generally a bad idea to spoof vendor id as lots of
kernel and user space code gets confused and may take unoptimized paths.

This implements DMABuf allocation type in the virtio wayland
device.
We attempt to locate a supported DRM device prior to engaging
the device jail. If found, the DRM device is passed to the
wayland device code and used to serve DMABuf allocations.
DMABuf support can be disabled by not providing crosvm with
access to any DRM device nodes.
The guest is expected to handle the case when DMABuf allocation
fails and fall-back to standard shared memory.
This initial change uses DRM directly but is structured in a
way that would allow the allocator to be replaced by minigbm
with minimal effort.

This creates a trait that different architectures can implement to
support running Linux VMs.
In the implementation on X86 we remove some error and return errors
from lower-level modules as appropriate. These modules now implement
the Error trait so we can get meaningful descriptions without an extra
error from the calling function. This still keeps all the ifdefs in
linux.rs for now until we have another implementation to use for ARM.
