* objfiles.h (SECT_OFF_DATA, SECT_OFF_TEXT, SECT_OFF_BSS,
SECT_OFF_RODATA): Define as functions of OBJFILE. Add
sect_index_text, sect_index_data, sect_index_rodata,
sect_index_bss to objfile structure.
* gdb-stabs.h (SECT_OFF_DATA, SECT_OFF_TEXT, SECT_OFF_BSS,
SECT_OFF_RODATA): Remove.
* objfiles.c (allocate_objfile): Initialize
sect_index_{text,data,bss,rodata} to -1, for error detection.
* symfile.c (default_symfile_offsets): Initialize
sect_index_{text,data,bss,rodata} from bfd information.
* xcoffread.c (xcoff_symfile_offsets): Ditto.
* somread.c (som_symfile_offsets): Initialize
sect_index_{text,data,bss,rodata}.
* coffread.c, dbxread.c, elfread.c, hp-psymtab-read.c,
hp-symtab-read.c, hpread.c, mdebugread.c, minsyms.c,
mipsread.c, objfiles.c, os9kread.c, pa64solib.c, partial-stab.h,
remote-os9k.c, remote-vx.c, remote.c, rs6000-nat.c, somsolib.c,
stabsread.c, symfile.c, xcoffread.c:
Update use of SECT_OFF_{TEXT,DATA,BSS,RODATA} to depend on the
current objfile.
* xcoffread.c: Add new field objfile to find_targ_sec_arg.
