* Makefile.in (hpread.o, pa64solib.o, somsolib.o): Add $(hppa_tdep_h)
	* hppa-tdep.c (hppa_objfile_priv_data): New.
	(SR4EXPORT_LDIL_OFFSET, SR4EXPORT_LDO_OFFSET): Use
	HPPA_INSTRUCTION_SIZE.
	(read_unwind_info): Use objfile_data to reference unwind info.
	(find_unwind_entry): Likewise.
	(hpread_adjust_stack_address): Move to hpread.c.
	(_initialize_hppa_tdep): Register hppa objfile data.
	* hppa-tdep.h (HPPA_INSTRUCTION_SIZE): Define.
	(unwind_table_entry, unwind_stub_types): Move from tm-hppa.h.
	(obj_unwind_info, obj_private_struct): Move from tm-hppa.h, and rename
	with hppa_ prefix.
	* hpread.c (hppa-tdep.h): Include.
	(hpread_adjust_stack_address): Move from hppa-tdep.c.
	(hpread_read_function_type, hpread_read_doc_function_type)
	(hpread_process_one_debug_symbol): Call hpread_adjust_stack_address
	directly. Use objfile_data to access solib data.
	* pa64solib.c (hppa-tdep.h): Include.
	(pa64_solib_add_solib_objfile): Use objfile_data to access solib data.
	* somsolib.c (hppa-tdep.h): Include.
	(som_solib_add_solib_objfile): Use objfile_data to access solib data.
	* config/pa/tm-hppa.h (frame_info, frame_saved_regs, value, type)
	(inferior_status): Remove unused forward declarations.
	(INSTRUCTION_SIZE): Move to hppa-tdep.c.
	(unwind_table_entry, unwind_stub_types, obj_unwind_info)
	(obj_private_struct): Move to hppa-tdep.h.
	(HPREAD_ADJUST_STACK_ADDRESS): Remove.

TODO/maybe: think about splitting this into two parts; the unwind data is
common to all hppa targets, but is only used in this file; we can register
that separately and make this static. The solib data is probably hpux-
specific, so we can create a separate extern objfile_data that is registered
by hppa-hpux-tdep.c and shared with pa64solib.c and somsolib.c. */
