The blkio block driver will need to look up the file descriptor for a given pointer. This is possible in softmmu builds where the RAMBlock API is available for querying guest RAM. Add stubs so tools like qemu-img that link the block layer still build successfully. In this case there is no guest RAM but that is fine. Bounce buffers and their file descriptors will be allocated with libblkio's blkio_alloc_mem_region() so we won't rely on QEMU's qemu_ram_get_fd() in that case.
