* objfiles.h (struct obj_section): Remove addr and endaddr fields.

Browse Source 
(obj_section_offset, obj_section_addr, obj_section_endaddr): New
	macros.
	* objfiles.c (add_to_objfile_sections): Don't set addr, endaddr
	and offset.  Use size_t instead of unsigned long.
	(build_objfile_section_table): Use size_t instead of unsigned
	long.
	(objfile_relocate): Don't relocate s->addr and s->endaddr, they're
	gone.
	(find_pc_sect_section): Use obj_section_addr and
	obj_section_endaddr.
	* symfile.c (symfile.c): Remove code that maps sections
	offsets in "addr" to the object's sections.
	* blockframe.c (find_pc_partial_function): Use obj_section_endaddr.
	* gcore.c (gcore_create_callback): Use obj_section_addr and
	obj_section_endaddr.
	* maint.c (print_objfile_section_info): Likewise.
	* printcmd.c (sym_info): Use obj_section_addr and
	obj_section_endaddr.
	* symtab.c (fixup_section): Likewise.

/* This is a SVR4/SunOS specific hack, I think. In any event, it
screws RS/6000. sym_offsets should be doing this sort of thing,
because it knows the mapping between bfd sections and
section_offsets. */
/* This is a hack. As far as I can tell, section offsets are not
target dependent. They are all set to addr with a couple of
exceptions. The exceptions are sysvr4 shared libraries, whose
offsets are kept in solib structures anyway and rs6000 xcoff
which handles shared libraries in a completely unique way.
Section offsets are built similarly, except that they are built
by adding addr in all cases because there is no clear mapping
from section_offsets into actual sections. Note that solib.c
has a different algorithm for finding section offsets.
These should probably all be collapsed into some target
independent form of shared library support. FIXME. */
