Jakob Vukalovic 6a7b20d48b cros_fdt: Rename FdtWriter to Fdt 
Currently crosvm has no support for generating device tree nodes for
platform devices assigned via VFIO. That limits usage of platfor VFIO
devices in VMs.

Additional DT nodes can be added to the DT via the overlay mechanism.
This and the following patches add support for amending the VM device
tree by adding support for device tree overlays.

As the first step, rename the FdtWriter struct to Fdt. It makes sense
to use a more general name as the crate gains additional features.

Bug: b/296796644
Test: cd cros_fdt && cargo test

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
