Dodji Seketeli b00ba10e1d xml reader: Fix recursive qualified & reference type definition 
This is a followup patch for the fix for
https://bugzilla.redhat.com/show_bug.cgi?id=1944088, which was in the
patch:

    commit 51ae965305

	abixml reader: Fix recursive type definition handling

After that patch, I noticed that qualified and reference types also
need to be able to handle the case where their underlying/pointed-to
type recursively refers to the type being created.  Just like typedef
and pointer types in that patch.

This patch thus adjusts build_qualified_type_decl and
build_reference_type_def to support that.  It also adjusts the
qualified_type_def and reference_type_def classes to support being
created without underlying/pointed-to type initially.

	* include/abg-ir.h (qualified_type_def::qualified_type_def):
	Declare a constructor with no underlying type.
	(reference_type_def::reference_type_def): Declare a constructor
	with no pointed-to type.
	(reference_type_def::set_pointed_to_type): Declare new method.
	* src/abg-ir.cc (qualified_type_def::priv::priv): Define a
	constructor that takes no underlying type.
	(qualified_type_def::build_name): Make this work even on
	incomplete types with no underlying type.  In that case, this
	behaves like if the underlying type is "void".
	(qualified_type_def::qualified_type_def): Define a constructor
	that takes no underlying type.
	(qualified_type_def::get_size_in_bits): Make this work on
	incomplete types with no underlying type.
	(qualified_type_def::set_underlying_type): Adjust to properly
	update this type when a new underlying type is set.  Particularly,
	its name and the lookup maps from the type scope.
	(reference_type_def::reference_type_def): Define a constructor
	that takes no pointed-to type.
	(reference_type_def::set_pointed_to_type): Define new function.
	* src/abg-reader.cc (build_qualified_type_decl): Construct the
	qualified type early before we try to construct its underlying
	type.  Associate this incomplete type with the type-id.  Then try
	to construct the underlying type.  During its construction, if
	this incomplete qualified type is needed due to recursion then it
	can be used, leading to just one qualified type being used as it
	should be.
	(build_reference_type_def): Likewise for building incomplete
	reference type first before its pointed-to type.

README 

This is the Application Binary Interface Generic Analysis and
Instrumentation Library.

It aims at constructing, manipulating, serializing and de-serializing
ABI-relevant artifacts.

The set of artifacts that we are intersted is made of quantities like
types, variable, fonctions and declarations of a given library or
program.  For a given library or program this set of quantities is
called an ABI corpus.

This library aims at (among other things) providing a way to compare
two ABI Corpora (apparently the plural of corpus is copora, heh,
that's cool), provide detailed information about their differences,
and help build tools to infer interesting conclusions about these
differences.
