acc162000f Add conditional compilation for unix-only crates
Instead of configuring which crates to --exclude in
test_config.py, we can use conditional compilation to
exclude code that is not supported on windows.

This allows more fine-grained control and also allows
us to use plain cargo for building without complicated
configuration and exclusions.

36bb092978 qcow_utils: add qcow feature to Cargo.toml
When the qcow2 support was moved behind a Cargo feature flag
(--features=qcow), the qcow_utils crate had some of its code modified to
check for `#[cfg(feature = "qcow")]`, but this feature was not actually
present in its Cargo.toml file, so enabling it had no effect.

This can be verified by checking the libqcow_utils.so contains a
create_qcow_with_size() function that does more than just return
-EINVAL.

4fea399df9 Reformat imports
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.

ae5118f5c7 Enable windows tests for a few crates
Run tests for sys_util_core, poll_token_derive and balloon_control on
windows.

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
file to the crate.

The patch modifies and uses the script that runs linux tests.
This patch also allows us to
- build/test child crate even if parent crate has disabled build/test.
- avoid building crosvm if it is not explicitly specified.

RIP short lived .windows_build_test_skip. You allowed us to run noop
kokoro tests.

f9b035d50c Support composite disks.
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.

aecf9a4dee edition: Remove extern crate lines
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;

59bb712992 edition: Update qcow and qcow_util to 2018 edition
Separated out of CL:1513058 to make it possible to land parts
individually while the affected crate has no other significant CLs
pending. This avoids repeatedly introducing non-textual conflicts with
new code that adds `use` statements.

94923406ae qcow_utils: do not close given fds in convert_to_* functions
The `convert_to_*` functions take ownership of the passed FDs even
though they should not according to the function's contract. This change
clones the passed FDs so that the caller can retain ownership of its
FDs.

This change also wraps most of the implementations in catch_unwind so
that panics do not unwind past FFI boundaries, which is undefined
behavior.

7f9b9ea344 qcow: add convert API and export it in qcow_utils
This will be used in vm_concierge's ExportDiskImage function in order to
allow a minimal qcow2 image to be written on the fly (containing only
the required clusters in a tightly-packed image file). It also allows
future flexibility to change the underlying disk image file format while
still exporting qcow2 images (e.g. via `vmc export`).

For testing, add a qcow_img `convert` command, which can convert
between raw and qcow2 as both source and destination.

BUG=None
TEST=Use qcow_img to convert a raw image to qcow2 and back and verify
     its contents are the same as the original.

2dcb632405 qcow: Set refcounts for initial clusters.
All qcow clusters need to have their refcounts set. Add a `new` method
to `Qcowfile` and use it instead of just headers from the library.

The new method will loop over the initial clusters and initialize their
refcounts.

Add a `create_qcow2` option to the main executable so there is a way to
test image creation that doesn't require DBUS and Concierge.
