548754cd2f Specify file paths via Path instead of PathBuf
Many functions took a reference to PathBuf, but then just passed the
parameter to File::open(), so they can be changed to a reference to
Path instead to avoid a potential allocation.

cf55111b9b acpi: FACS support, minor fixes for acpi forwarding.
User provided DSDT/MADT/FADT tables will have precedence
over crosvm generated data, with crosvm only overriding
critical FADT fields to match ACPI tables placement.
Also, this patch adds mandataory empty FACS structure.

Check the S1 capability by "#echo standby > /sys/power/state" from guest
side. Linux guest is suspended. And resume linux guest by "#crosvm resume
crosvm.sock" from host side.

020fbf04c2 x86_64: generate ACPI tables
Add acpi_rsdp_addr in boot_params to allow crosvm to pass
a physicall address of RSDP to the Linux guest kernel, so
that the linux guest kernel can parse the constructed ACPI
tables and enable the ACPI.

Although there is ACPI tables but as we still have "acpi=off"
in command line parameter, there is still no ACPI in guest kernel.

The ACPI construction refers to the implementation of the
Cloud-hypervisor commit:
