2ef476c9a2 Follow DW_AT_specification when looking up DW_AT_type attributes.
dwarf_attrval_*() will search the parent DIE referenced by a
DW_AT_abstract_origin attribute for the value of the DW_AT_type attribute.
Do the same thing for the DW_AT_specification attributes in variable
definitions emitted by GCC 6.2, and ensure that we return an error rather
than crashing if neither DW_AT_abstract_origin or DW_AT_specification is
found when looking for the value of the DW_AT_type attribute.

9c016dc4b2 API dwarf_attrval_flag() should properly handle an attribute with
(DWARF4) form DW_FORM_flag_present which implicitly indicates the
presence of the attribute. Manual page is updated to reflect this
change.

Note that this was previously fixed in the old libdwarf.
