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.

Test: py .\tools\impl\test_runner.py --arch x86_64

0108238474 Upstream windows build/test script
The patch also adds files to skip building and testing crates on
windows. When we run
```
tools/windows/build_test.py --skip_file_name .windows_build_test_skip
```

the build/test succeeds without actually doing anything as build/test
for all crates is skipped by creating '.windows_build_test_skip'.

993aa7fd49 crosvm: add option to use persistent TAP interface as network device
Currently we have two ways to enable networking on crosvm:

1) Pass all 3 of `--host_ip`, `--netmask` and `--mac` to have crosvm
create and configure a TAP device. This requires crosvm to either be run
as root, or to have the CAP_NET_ADMIN capability,

2) Have another process with the above privileges create and configure
the TAP device before exec'ing crosvm with the TAP FD still open and
passing it to crosvm with the `--tap-fd` argument.

None of these ways are very convenient for development as they either
require to get some privilege every time crosvm is invoked, or to use
another program (not distributed with crosvm) to do the setup.

This patch adds the `tap-name` command-line option which allows to
create a network device from a configured persistent TAP interface,
which doesn't require any kind of privilege.

A persistent TAP interface can be configured on the host as follows:

    # ip tuntap add mode tap user $USER vnet_hdr crosvm_tap
    # ip addr add 10.0.2.1/24 dev crosvm_tap
    # ip link set crosvm_tap up

Then after this one-time setup, $USER will be able to use the
`crosvm_tap` interface by simply passing `--tap-name crosvm_tap` to
crosvm, without any extra option or tool.

This is convenient for development setups as one just needs to
permanently configure the TAP interface using standard Linux tools on
the host once.

BUG=None
TEST=Check that networking works after passing `--tap-name` to crosvm.

e392c46953 base: Add WaitContext
This is a layer above PollContext with a more generic interface.
As PollContext is used so widely, this is quite a large change
in order to accomodate the interface update, especially with the
use of RawDescriptor. In some cases this has caused an echo
of updates to RawDescriptor, which is fine because of our eventual
goal to move the whole codebase to it regardless.

Note there are a few instances of forcing the RawDescriptor update
chain to stop, ex. ioctl. This is to keep the scope of this CL
concentrated and avoid changing entire other areas.

Note that this CL leaves out a few additional pieces of work:
 - The sole usage of EpollContext over PollContext (event_loop),
which poses a bigger challenge for interface changes
 - Full PollToken renaming, which is a tiny change turned difficult
due to the unavailability of type aliases for traits.
 - Renaming certain methods which have been updated to use
RawDescriptor such as keep_fds. Some have enough dependencies that
they are worth avoiding to keep this CL pointed, but will be
addressed in future CLs to make sure the whole codebase is on the
fd->descriptor train

6b19695c81 Add "base" crate and transition crosvm usages to it from sys_util
For now, this crate simply re-exports all of sys_util, but it will
be updated to provide new interfaces when needed. This is the
first step to making crosvm not directly depend on sys_util, so
that we can make the interface changes we need without fear of
negatively affecting (i.e. completely breaking) other usages
within chromeos.

4cbcc26f5c Virtio-net: Add multi queues in multi threads
In order to support 2 vq pairs for virtio-net, this patch create 2
sockets in one tap interface,  2 vq pairs(rx/tx) and 2 threads in
device model, So one vq pair has one thread and one socket in tap
corresponding.

On my SkyLake desktop with crosvm and ubuntu 18.04 guest:
If run one iperf server on host and one iperf client in guest, 2 vq
pairs has the same netwrok bandwidth as 1 vq pair, the bandwidth is
5.99Gbits/sec

If run two iperf server on host and two iperf client in guest,
In 1 vq pair mode, two iperf cliens bandwidth are 3.19Gbits/sec and
3.18Gbits/sec.
In 2 vq pairs mode, two iperf clients bandwidth are 4.87Gbits/sec and
4.86Gbits/sec.
So 2 vq pairs improve net bandwidth 52.7% compared with 1 vq pair in
this case.

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;

the variant means in human terms. Worse, many errors (like the one shown
below) already had error strings written but were being printed from the
calling code in the less helpful Debug representation anyway.

Before:
    [ERROR:src/main.rs:705] The architecture failed to build the vm: NoVarEmpty

After:
    [ERROR:src/main.rs:705] The architecture failed to build the vm: /var/empty doesn't exist, can't jail devices.

49fa08f17b net_util: Get tap interface name when using a raw fd
We use the tap device interface name in some ioctls.  When we are
creating a Tap struct from a raw fd make sure that we also grab the
interface name so that these ioctls don't fail later.

5bbbf61082 lint: Resolve the easier clippy lints
Hopefully the changes are self-explanatory and uncontroversial. This
eliminates much of the noise from `cargo clippy` and, for my purposes,
gives me a reasonable way to use it as a tool when writing and reviewing
code.

Here is the Clippy invocation I was using:

5f787217cc net: Allow passing in a configured tap fd on the command line
Allow the process that spawned crosvm to pass in a configured tap file
descriptor for networking.  If this option is provided then crosvm will
ignore the other networking related command line flags (like mac
address, netmask, etc).

Passing in a configured tap device allows us to run crosvm without
having to give it CAP_NET_ADMIN.

BUG=none
TEST=Start a container and verify that networking still works

d7f036281d net_util: Fix-up failing tests and add a little more coverage
We can't really mock out the underlying TAP ioctls unless we introduce
another layer of abstraction. Instead, this CL allows a test to pass
if the reason that it failed was a permission denial as we would
expect running on Paladins as non-root.

Also adds net_util to the build_test test targets.
