Removed _bfd_debug_info_start, _bfd_debug_info_end and
_bfd_debug_info_accumulate, which were never used.
(BFD_JUMP_TABLE_GENERIC, BFD_JUMP_TABLE_COPY): Defined.
(BFD_JUMP_TABLE_CORE, BFD_JUMP_TABLE_ARCHIVE): Defined.
(BFD_JUMP_TABLE_SYMBOLS, BFD_JUMP_TABLE_RELOCS): Defined.
(BFD_JUMP_TABLE_WRITE, BFD_JUMP_TABLE_LINK): Defined.
* All backends: Changed to use the new BFD_JUMP_TABLE_* macros
rather than the single JUMP_TABLE macro. Removed many of the
weird macro definitions needed to support the monolithic
JUMP_TABLE.
* bfd-in.h (JUMP_TABLE): Removed.
* libbfd-in.h: Define a bunch of macros, and declare a few
functions, for use with the new BFD_JUMP_TABLE_* macros.
* libbfd.c (_bfd_dummy_new_section_hook): Removed.
(bfd_false): Set bfd_error_invalid_operation.
(bfd_nullvoidptr): Likewise.
(bfd_n1): New function.
(_bfd_nocore_core_file_matches_executable_p): Renamed from
_bfd_dummy_core_file_matches_executable_p.
(_bfd_nocore_core_file_failing_command): Similar rename. Set
bfd_error_invalid_operation.
(_bfd_nocore_core_file_failing_signal): Likewise.
(_bfd_generic_get_section_contents): Renamed from
bfd_generic_get_section_contents. Changed all callers.
(_bfd_generic_set_section_contents): Similar rename.
* ieee.c: #if 0 out ieee_bfd_debug_info_start,
ieee_bfd_debug_info_end, ieee_bfd_debug_info_accumulate. They
were never called.
* bfd-in2.h: Rebuilt.
* libbfd.h: Rebuilt.
