    PR26348, Malloc error in write_zeros

    This adds a few more sanity checks on ELF objects, and a BFD flag to
    disable objcopy and strip when fuzzed input files belong in the "too
    hard" basket.

            PR 26348
            * bfd.c (struct bfd): Add read_only.
            * elfcode.h (elf_swap_shdr_in): Test both sh_offset and sh_size.
            Set read_only on warning.
            (elf_object_p): Sanity check program header alignment.  Set
            read_only on warning.
            * bfd-in2.h: Regenerate.
            PR 26348
            * objcopy.c (copy_object): Report file name with endian error.
            Error and return on abfd->read_only.
