517b009996 direct_irq: support forwarding of ACPI fixed events
Userspace counterpart for the kernel irq-forward module change
CL:3599199 which adds support for physical ACPI fixed events
forwarding, very similar to physical GPE forwarding.

The mentioned kernel change also modifies the ioctl interface to unify
both types of ACPI events forwarding, but in a backward compatible way,
so this commit is not necessary to keep GPE forwarding working, but it
is required for adding support for fixed events forwarding.

d61e24be2c Revert "direct_irq: Add support for host wakeup capable IRQs"
This reverts commit 0ac97979b6.

Reason for revert: This static configuration for wakeup IRQs is
no longer needed since we have a mechanism for automatic dynamic
configuration of wakeup IRQs based on requests from ChromeOS VM.

BUG=b:228449597
TEST=Boot ManaTEE and verify wakeup from touchpad and other devices.

e6fb841b3f direct_irq: allow to register eventfd for GPE
In ACPI world multiple GPEs (HW wires signaling arbitrary event)
can be associated with single SCI. Any pending GPE causes SCI
to be fired and appropriate GPE handler dispatched. In order
to pass-through GPE to the guest and take virtualization actions,
host kernel provides mechanism to bind physical GPE with SCI eventfd and
forward that information the the event listener (crosvm or KVM most likely).

Add userspace counterpart to host kernel GPE forwarding module
implemented in CL:3488959.

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.

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'.

01527e39b3 devices: vfio: add support for VFIO_REGION_INFO_CAP_MSIX_MAPPABLE
For MSIX-capable PCI devices, some BAR regions are described using
VFIO_REGION_INFO_CAP_MSIX_MAPPABLE:

  The MSIX mappable capability informs that MSIX data of a BAR can be
  mmapped which allows direct access to non-MSIX registers which
  happened to be within the same system page.

Add support for this capability so that VfioRegion stores the correct
mmaps information.

Also, fix a couple break conditions to avoid breaking out early.

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.
