elf_backend_copy_indirect_symbol so that backend has a chance to
copy other necessary fields.
* elf-bfd.h (struct elf_backend_data): Update description of
elf_backend_copy_indirect_symbol.
* elf.c (_bfd_elf_link_hash_copy_indirect): Bail out after
copying flags if this is a weakdef.
* elfxx-ia64.c (elfNN_ia64_hash_copy_indirect): Likewise.
(elfNN_ia64_aix_add_symbol_hook): Use elf_link_hash_lookup rather
than bfd_link_hash_lookup.

reloc processing for weakdefs.

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.
