PR 868
* libbfd.c (bfd_realloc_or_free): New function. Performs like bfd_realloc, but if the (re)allocation fails, the pointer is freed. * libbfd-in.h: Prototype. * libbfd.h: Regenerate. * bfdio.c (bfd_bwrite): Use the new function. (bfd_seek): Likewise. * bfdwin.c:(bfd_get_file_window): Likewise. * elf-strtab.c (_bfd_elf_strtab_add): Likewise. * elf32-ppc.c (ppc_elf_relax_section): Likewise. * elf32-xtensa.c (vsprintf_msg): Likewise. * mach-o.c (bfd_mach_o_core_fetch_environment): Likewise. * stabs.c (_bfd_link_seciton_stabs): Likewise. * vms-misc.c (_bfd_vms_get_record): Likewise. * vms-tir.c (check_section): Likewise. * vms.c (vms_new_section_hook): Likewise. * elf32-arm.c (elf32_arm_section_map_add): Check that the allocation of sec_data->map succeeded before using it. * elflink.c (elf_link_output_sym): Do not overwrite finfo-> symshndxbuf until it is known that the reallocation succeeded.
