c434dee664 * elf64-x86-64.c: Major rework that introduces all recent changes
to the x86-64 backend.  Get a closer match to elf32-i386.
	(struct elf64_x86_64_dyn_relocs): Rename from
	elf64_x86_64_pcrel_relocs_copied, add additional fields.  Change
	all users.
	(struct elf64_x86_64_link_hash_table): Add short cuts to some
	sections.
	(link_hash_newfunc): Rename from elf64_x86_64_link_hash_newfunc,
	remove casts, initialize new hash members.
	(create_got_section): New.
	(elf64_x86_64_create_dynamic_sections): New.
	(elf64_x86_64_copy_indirect_symbol): New.
	(elf64_x86_64_check_relocs): Don't allocate space for dynamic
	relocs, .got or .relgot here but do it in allocate_dynrelocs.
	Reference count possible .plt and .got entries.  Don't test input
	section SEC_READONLY here to try to avoid copy relocs, and keep
	dyn_relocs regardless of ELF_LINK_NON_GOT_REF.  Don't set
	DF_TEXTREL here.  Delay setting of variables until needed.  Cache
	pointer to "sreloc" section in elf_section_data. Tweak condition
	under which .got created.  Report files with bad relocation
	section names.
	(elf64_x86_64_gc_sweep_hook): Sweep dyn_relocs and local_dynrel.
	Reference count possible .plt entries.  Don't deallocate .got and
	.relgot space here.
	(elf64_x86_64_adjust_dynamic_symbol): Handle nocopyreloc.  Don't
	do copy reloc processing for weakdefs.  Remove redundant casts and
	aborts.  Delay setting of vars until needed.  Move creation of
	dynamic symbols and allocation of .plt and .rela.plt to
	allocate_dynrelocs.  Replace BFD_ASSERT with abort.
	(WILL_CALL_FINISH_DYNAMIC_SYMBOL): New.
	(allocate_dynrelocs): New.
	(readonly_dynrelocs): New.
	(elf64_x86_64_size_dynamic_sections): Call readonly_dynrelocs.
	Allocate space for dyn relocs.  Replace BFD_ASSERT with abort.
	Zero out the dynamic allocated content space.
	(elf64_x86_64_discard_copies): Removed.
	(elf64_x86_64_relocate_section): Make use of dynamic section
	short-cuts.  Localise vars, and delay setting.  Better error
	reporting, replace BFD_ASSERT with abort.  Check
	ELF_LINK_HASH_DEF_DYNAMIC to see if a symbol is not defined in the
	regular object file and tread the weak definition as the normal
	one.  Don't discard relocs for undefweak or undefined symbols and
	check !DEF_REGULAR as well as DEF_DYNAMIC in test for avoided copy
	relocs.
	(elf64_x86_64_finish_dynamic_symbol): Don't copy relocs for
	symbols that have been forced local.  Use same test to decide if
	we can use a relative reloc for got as relocate_section.  Expand
	SHN_UNDEF comment.  Move expressions out of function calls.
	Replace BFD_ASSERT with abort.
	(bfd_elf64_bfd_final_link): Removed.
	(elf_backend_copy_indirect_symbol): Define.

dc810e3900 Touches most files in bfd/, so likely will be blamed for everything..
o  bfd_read and bfd_write lose an unnecessary param and become
   bfd_bread and bfd_bwrite.

o  bfd_*alloc now all take a bfd_size_type arg, and will error if
   size_t is too small.  eg. 32 bit host, 64 bit bfd, verrry big files
   or bugs in linker scripts etc.

o  file_ptr becomes a bfd_signed_vma.  Besides matching sizes with
   various other types involved in handling sections, this should make
   it easier for bfd to support a 64 bit off_t on 32 bit hosts that
   provide it.

o  I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
   generally available.  They now cast their args to bfd_vma and
   bfd_byte * as appropriate, which removes a swag of casts from the
   source.

o  Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
   aout-encap.c.

o  Zillions of formatting and -Wconversion fixes.
