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.
binutils/
PR 26348
* objcopy.c (copy_object): Report file name with endian error.
Error and return on abfd->read_only.
