[src/trunk]: src Replace boot_ustar with xxboot_ustarfs.
details: https://anonhg.NetBSD.org/src/rev/ba780a929990

description:
Replace boot_ustar with xxboot_ustarfs.
The old boot_ustar had many hard coding and was small(<1KB).
The new xxboot_ustarfs is a part of integrated larger(<8KB) xxboot.
We had to maintain three similar but not the same bootloaders, but
now we have two!
