Free linker hash table from bfd_close.
Also tidies numerous error exit paths in various link_hash_table_create functions that failed to free memory. include/ * bfdlink.h (struct bfd_link_hash_table): Add hash_table_free field. bfd/ * archive.c: Include bfdlink.h. (_bfd_archive_close_and_cleanup): Call linker hash_table_free. * bfd.c (struct bfd): Add is_linker_output field. * elf-bfd.h (_bfd_elf_link_hash_table_free): Update prototype. * linker.c (_bfd_link_hash_table_init): Set up hash_table_free, link.hash and is_linker_output. (_bfd_generic_link_hash_table_free): Replace bfd_link_hash_table* param with bfd*. Assert is_linker_output and link.hash, and clear them before exit. * elf-m10300.c (elf32_mn10300_link_hash_table_free): Replace bfd_link_hash_table* param with bfd*. Hack is_linker_output and link.hash so we can free two linker hash tables. (elf32_mn10300_link_hash_table_create): Create static_hash_table first. Clean up on errors. Set hash_table_free pointer. * elf32-arm.c (elf32_arm_link_hash_table_free): Replace bfd_link_hash_table* param with bfd*. (elf32_arm_link_hash_table_create): Clean up on errors. Set hash_table_free pointer. * elf32-avr.c, * elf32-hppa.c, * elf32-i386.c, * elf32-m68hc1x.c, * elf32-m68k.c, * elf32-metag.c, * elf32-nios2.c, * elf32-xgate.c, * elf64-ia64-vms.c, * elf64-ppc.c, * elf64-x86-64.c, * elflink.c, * elfnn-aarch64.c, * elfnn-ia64.c, * elfxx-sparc.c, * xcofflink.c: Similarly. * simple.c (bfd_simple_get_relocated_section_contents): Save and clear link.next before creating linker hash table. Clean up on errors, and restore link.next on exit. * elf32-m68hc1x.h (m68hc11_elf_bfd_link_hash_table_free): Delete. * elf32-xgate.h (xgate_elf_bfd_link_hash_table_free): Delete. * elfxx-sparc.h (_bfd_sparc_elf_link_hash_table_free): Delete. * libcoff-in.h (_bfd_xcoff_bfd_link_hash_table_free): Delete. * hash.c (bfd_hash_table_init_n): Free table on error. * libbfd-in.h (_bfd_generic_link_hash_table_free): Update proto. * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. * libcoff.h: Regenerate.
