The current model of loader copy "rom blobs" and kept in memory until
a reset occurs and waste host memory.
This serial of patches uses private reset handlers to load from hard
disk on reset, which could make loader framework more dynamic and
reduce the memory consumption of QEMU process.

use image_file_reset to reload initrd image
use uimage_reset to reload uimage
use elf_reset to reload elf image
free the memory malloced by load_at()
