Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.
* bfd.c (bfd_get_relocated_section_contents): Now a function, tries calling
routine from input bfd target vector for bfd_indirect_link_order. Put a
declaration into the header file.

* elf32-mips.c (gprel16_with_gp): New function, split out from
mips_elf_gprel16_reloc.
(mips_elf_gprel16_reloc): Call it. If output bfd target vector isn't elf
flavoured, abort, since it's assumed to be elf in some of this code, including
the code that looks up the gp value.
(elf32_mips_get_relocated_section_contents): New function, modified from
bfd_generic_get_relocated_section_contents to deal with passing gp to
gprel16_with_gp.

(bfd_section_from_shdr): In SHT_STRTAB case, check bfd_section,
not rawdata. Don't set rawdata if e_shstrndx. Use bfd_section
rather than rawdata in commented out code. In SHT_REL[A] case,
don't bother to check elf_section_data of section returned by
section_from_elf_index.
(elf_fake_sections): Set bfd_section, not rawdata. Don't set
size.
(elf_map_symbols): Don't set elf_num_section_syms. Don't create

* libelf.h (_bfd_elf_make_section_from_shdr): Declare.
* elfcode.h (bfd_section_from_shdr): Use new function
_bfd_elf_make_section_from_shdr to create BFD sections. If a
reloc section does not use the main symbol table, or it is part of
the process image, treat it as a normal section, not relocs.
* elf32-mips.c (mips_elf_section_from_shdr): Use new function
_bfd_elf_make_section_from_shdr.

have already been read in.

18 to 16.
(PCREL16_EXPANSION_ADJUSTMENT): Define.
(mips_relocate_refhi): Take adjust argument.
(mips_relocate_section): Handle reloc offsets stored in section
used_by_bfd field. Call mips_relax_pcrel16 to handle details of
expanding an out of range PCREL16. Keep trace of adjustments
required by expansions. Set s and unset h when converting a reloc
from undefined to section. Change handling of PC relative relocs:
if against a section, they are correct in the object file, if
against an external symbol they are pcrel_offset.
