We commonly do a dwarf_attr_integrate followed by dwarf_formref_die,
with no care for the Dwarf_Attribute, so I captured that idiom in an
inline function.
* dwarf_wrappers.h (dwarf_attr_die): New.
* dwarf_wrappers.cxx (dwarf_type_name): Call dwarf_attr_die.
* dwflpp.cxx (dwflpp::print_members): Ditto.
(dwflpp::find_struct_member): Ditto.
* tapsets.cxx (dwarf_derived_probe::saveargs): Ditto.
(uprobe_derived_probe::saveargs): Ditto.
(resolve_tracepoint_arg_type): Ditto.
(tracepoint_derived_probe::build_args): Ditto.

* dwarf_wrappers.cxx (dwarf_type_name): Moved here from tapsets.cxx, and
added a variant that returns a string for easier ostreaming.
* dwflpp.cxx (dwflpp::print_members): Use dwarf_type_name for errors.
(dwflpp::find_struct_member): Ditto.
(dwflpp::translate_components): Ditto.
(dwflpp::translate_final_fetch_or_store): Ditto.
(dwflpp::literal_stmt_for_pointer): Ditto.
* tapsets.cxx (dwarf_derived_probe::saveargs): Pass die to
dwarf_type_name by pointer instead of reference.
(uprobe_derived_probe::saveargs): Ditto.
(resolve_tracepoint_arg_type): Ditto.

Elfutils prior to 0.143 didn't use attr_integrate when looking up the
decl_file or decl_line, so the attributes would sometimes be missed.
For those old versions, we define custom implementations to do the
integration.
* dwarf_wrappers.cxx (dwarf_decl_file_integrate): New.
(dwarf_decl_line_integrate): New.
* dwarf_wrappers.h: Add macros to redirect calls to the above functions.
* dwflpp.cxx (dwflpp::iterate_over_labels): Replace a manual attribute
lookup that is the same as dwarf_decl_line.

The dwarf_diename in elfutils learned a long time ago to use
dwarf_attr_integrate when looking up the name. Our minimum elfutils
0.126 has this, so we don't need to kludge it ourselves.

It's not a terribly clean split, but moving it helps reveals some of the
knots that need to be untangled.

New dwarf_wrappers.h, dwarf_wrappers.cxx for for idiomatic access to
libdwarf and refactoring somethings out of the giant classes in tapsets.cxx.
