Calling dwarf_peeled_die_type with a NULL results pointer is an error,
check early that result is not NULL so dwarf_formref_die and
dwarf_peel_type won't try to set the NULL Dwarf_Die.
* backends/libebl_CPU.h (dwarf_peeled_die_type): Move check
for results == NULL to start of function.

binutils 2.40 introduces DW_TAG_unspecified_type for assembly
functions with an unknown return type. This breaks the
run-funcretval.sh testcase because dwfl_module_return_value_location
returns an error for such functions because it cannot determine the
return value location. Fix that by treating DW_TAG_unspecified_type
as if the DIE doesn't have a DW_AT_type.
Also update the testcase to explicitly checking for
DW_TAG_unspecified_type and printing "returns unspecified type".

On the low level, they are the same as pointers. The change needs to be
done for all backends, so define a function and a macro to avoid
repetition. Also add a native test, which has to be implemented in C++.
Add the configure check for it.

We used to do several sanity checks when the ebl backend libraries
were loaded to make sure there was no version mismatch. When initializing
the backend we passed the current Ebl struct size so the library could
check it supported the given Ebl struct and we checked that the init
method returned the correct build time module version string. Neither
are necessary now that the backends are builtin.
Remove both the struct size check and the MODVERSION string (which
wasn't actually checked anymore). Make the init function return the
given Ebl handle or NULL on error (no init function currently indicates
any error).

Add new function dwarf_peel_type. Some type annotations in DWARF are
specified by modifier tag type wrappers instead of attributes.
For type aliases (typedef) and qualifiers (const, volatile, restrict)
tags dwarf_peel_type follows the DW_AT_type attributes till it finds
a base, user-defined, reference or pointer type DIE.
Use this new function in the backends for return type DIEs (replacing
the existing dwarf_peel_type there) and in dwarf_aggregate_size so
it can provide the sizes for qualified types too. Add a new version
and testcase for the new dwarf_aggregate_size functionality.

The DW_TAG_mutable_type was only mentioned in an early draft of DWARFv3.
But was removed because there are no C++ mutable qualified types. It was
replaced by a new attribute DW_AT_mutable on DW_TAG_member DIEs. The new
attribute is available in dwarf.h.
http://dwarfstd.org/ShowIssue.php?issue=050223.1
DW_TAG_mutable_type was only used internally in some backends (which
just ignored it anyway). dwarves did use it to turn it into a string
value, libabigail used it and ignored it (patches to remove sent).
GCC, GDB and binutils don't use nor define it.

dwarf_attr () or dwarf_form () functions leave typedie NULL when they fail
because of missing attribute or unexpected form. In such cases first check
the DIE exists and return error instead of calling dwarf_tag () and crashing.
This also happens in the testsuite with native tests when elfutils is build
without DWZ support on a distro that uses DWZ DWARF compression on system
libraries. Only the backends used dwarf_tag () directly without checking,
all other uses in elfutils already checked whether the given DIE was NULL.
