Subject: [PATCH] Some changes for option roms: - don't make users pick the
 name. Names for option roms are in the v3-defined format of pci%04x,%04x.rom
 with the vendor and device id filling in the %04x. - users pass in vendor and
 device id. - users pass in a dest. If the dest is 0, the address of the ROM
 image in FLASH is returned. If the address is non-zero, then the decmpressor
 is called, and it will make sure the ROM image is copied to the destination
 (even in the uncompressed case).

move qemu over to always using ROMFS
