crosvm has never actually supported running on a 32-bit x86 host, only
x86-64. Remove the cfg(target_arch = "x86") checks throughout the tree
to make this clear (and to simplify the code).
This doesn't affect the code running inside the guest, which can still
be a 32-bit x86 operating system if launched via --bios, for example.

A plugin might care to be immediately notified when a write

while the plugin calls back to resume the VM.
Unfortunately this means that multiple messages can be queued up in the

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.
