crosvm is switching the import style to use one import per line.
While more verbose, this will greatly reduce the occurence of merge
conflicts going forward.
Note: This is using a nightly feature of rustfmt. So it's a one-off
re-format only. We are considering adding a nightly toolchain to
enable the feature permanently.

Using dotfiles to disable/serialize test runs of a subset of crates does
not work well with third party crates as it forces us to commit the dot

The patch modifies and uses the script that runs linux tests.
This patch also allows us to

- avoid building crosvm if it is not explicitly specified.

Some judgement calls were made about unnecessary wrapping. Usually they
would get resolved by removing the wrapping or returning a convenient
error, but the ones that returned results for consistency with other
functions were added to the allow list.
The error handling in the usb code had a lot of unit error types which
is now a clippy lint. This was resolved by either removing the result
entirely or returning a convenient error.
The field_reassign_with_default lint is faulty and was added to the list
of supressions. This affected virtio-wayland code.

In Rust 2018 edition, `extern crate` is no longer required for importing
from other crates. Instead of writing:
extern crate dep;
use dep::Thing;
we write:
use dep::Thing;
In this approach, macros are imported individually from the declaring
crate rather than through #[macro_use]. Before:
#[macro_use]
extern crate sys_util;
After:
use sys_util::{debug, error};
The only place that `extern crate` continues to be required is in
importing the compiler's proc_macro API into a procedural macro crate.
This will hopefully be fixed in a future Rust release.
extern crate proc_macro;

Macros were previously imported through `#[macro_use] extern crate`,
which is basically a glob import of all macros from the crate. As of
2018 edition of Rust, `extern crate` is no longer required and macros
are imported individually like any other item from a dependency. This CL
fills in all the appropriate macro imports that will allow us to remove
our use of `extern crate` in a subsequent CL.

Previously, the getter and setter functions generated for a bitfield
struct by #[bitfield] all operated on primitive types like bool, u8, u16
etc.
This CL adds support for getters and setters defined in terms of
user-defined enums.
We make an enum bitfield-compatible by adding #[bitfield]. The number of
variants must be a power of 2.
#[bitfield]
enum TwoBits {
Zero = 0b00,
One = 0b01,
Two = 0b10,
Three = 0b11,
}
And then it may be used to specify a field in a bitfield struct.
#[bitfield]
struct Struct {
prefix: BitField1,
two_bits: TwoBits,
suffix: BitField5,
}
The generated getters and setters for this struct would have the
following signatures:
impl Struct {
fn get_prefix(&self) -> u8;
fn set_prefix(&mut self, val: u8);
fn get_two_bits(&self) -> TwoBits;
fn set_two_bits(&mut self, val: TwoBits);
fn get_suffix(&self) -> u8;
fn set_suffix(&mut self, val: u8);

- Check that the total number of bits is a multiple of 8. Previously, it

- Provide B0 .. B64 as shorthand for BitField0 .. BitField64.
- Use `bool` as the bool specifier rather than BitFieldBool.

Rustfmt currently does not touch the content of macro invocations. Also
it used to have a bug where if it changed indentation of a block of code
containing a multi-line macro invocation then the macro input would not
get correspondingly indented. That bug was visible across some of the
code here.
For example:
// rustfmt decides to un-indent the surrounding block:
let data_size_in_bytes = quote!(
( #( #field_types::FIELD_WIDTH as usize )+* ) / 8
);
// poorly formatted resulting code:
let data_size_in_bytes = quote!(
( #( #field_types::FIELD_WIDTH as usize )+* ) / 8
);
// should have been:
