Cody Schuffelen 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.
