Many of the errors touched in this CL already had helpful message
written! But those corresponding enum variants were never being
instantiated, and that bug was masked by Box<dyn Error>. For example see
the Error::LoadCmdline and Error::LoadKernel.
pub enum Error {
LoadCmdline(kernel_loader::Error),
...
}
Before this CL:
// Bug: boxes the underlying error without adding LoadCmdline
kernel_loader::load_cmdline(...)?;
After this CL:

Avoiding Box<dyn Error> makes it less likely that we display errors with

For example the following code which existed before this CL:
let dev_file = OpenOptions::new()
.read(true)
.write(true)
.open(dev_path)
.map_err(|e| Box::new(e))?;
This code converts io::Error directly to Box<dyn Error> without
providing enough context to debug what happened just from the io error
message.
The new code is forced to provide a dedicated Error enum variant which
carries a handwritten message and possibly further context:
.map_err(|e| Error::OpenVinput(dev_path.to_owned(), e))?;

I made a separate function to create each distinct VirtioDeviceStub.
Some advantages:
- Makes it easier to see the top level structure of create_devices
(which used to be 463 lines all in one function) -- how it loops
over inputs, how it decides to conditionally create particular
device types.
- Makes it clearer to follow when resources are shared across multiple
devices, particularly resource_bridge_wl_socket. The uses of
resource_bridge_wl_socket used to be 87 lines apart before this CL.
Now it spans only 27 lines so fits on one screen.
- Reduces indentation to leave more space for rustfmt to format the
device creation in a more readable way.
- Improves the ability to use short variable names whose meanings are
scoped to one device. For example wayland and balloon device
creation used to have to manipulate wayland_device_socket and
balloon_device_socket. Now create_wayland_device and
create_balloon_device can each deal with just a thing called
'socket' whose meaning is specific to the appropriate device.
