Dodji Seketeli 1483f6cb49 abilint: add the --show-type-use option 
"abilint --show-type-use <type-id> <abixml-file>" is a facility that
shows how a type defined in an abixml file is used.  That is, it emits
a textual representation of how the use a type is used up until the
function or global variable that constitutes an entry point in the API
corpus.  Here is an example of its use:

    test-read-write$ abilint --noout --show-type-use type-id-5 test17.xml
    Type ID 'type-id-5' is for type 'enum E'
    The usage graph for that type is:
    | -> enum E -> E S::m2 -> class S -> S* -> method void S::S()
    | -> enum E -> E S::m2 -> class S -> S* -> method void S::__base_ctor ()
    | -> enum E -> E S::m2 -> class S -> S* -> method void S::__comp_ctor ()
    | -> enum E -> E S::m2 -> class S -> S* -> method void S::S(S&)
    | -> enum E -> E S::m2 -> class S -> S* -> S& -> method void S::S(S&)
    | -> enum E -> E S::m2 -> class S -> S* -> S& -> S var
    | -> enum E -> E S::m2 -> class S -> S* -> S& -> E S::m2 -> class S -> S* -> method void S::S()
    | -> enum E -> E S::m2 -> class S -> S* -> S& -> E S::m2 -> class S -> S* -> method void S::__base_ctor ()
    | -> enum E -> E S::m2 -> class S -> S* -> S& -> E S::m2 -> class S -> S* -> method void S::__comp_ctor ()
    | -> enum E -> E S::m2 -> class S -> S* -> S& -> E S::m2 -> class S -> S* -> method void S::S(S&)
    | -> enum E -> E S::m2 -> class S -> S* -> S& -> E S::m2 -> class S -> S* -> S& -> method void S::S(S&)
    | -> enum E -> E S::m2 -> class S -> S* -> S& -> E S::m2 -> class S -> S* -> S& -> S var
    $

The screenshot above should be self explanatory.

This facility is useful to analyse type usage and find potential
issues in how libabigail represents some types.

To activate this feature, one needs to configure the package with the
configure option "--enable-show-type-use-in-abilint".

	* configure.ac: Define the --enable-show-type-use-in-abilint
	configure option.  It defines the WITH_SHOW_TYPE_USE_IN_ABILINT
	macro.
	* include/abg-reader.h (read_translation_unit): Add an overload
	that takes the read context.
	(get_types_from_type_id, get_artifact_used_by_relation_map):
	Declare new functions.
	* src/abg-reader.cc (get_types_from_type_id)
	(get_artifact_used_by_relation_map): Declare these functions as
	friend of the read_context type.
	(read_context::m_artifact_used_by_map):
	(read_context::key_type_decl): Replace the shared_ptr<type_base>
	type of the first parm by the equivalent type_base_sptr type.
	(read_context::{record_artifact_as_used_by,
	record_artifacts_as_used_in_fn_decl,
	record_artifacts_as_used_in_fn_type}): Add new methods guarded by
	the WITH_SHOW_TYPE_USE_IN_ABILINT macro.
	(get_types_from_type_id, get_artifact_used_by_relation_map): Define
	new functions guarded by the WITH_SHOW_TYPE_USE_IN_ABILINT macro.
	(read_translation_unit): Define new overload.
	(RECORD_ARTIFACT_AS_USED_BY, RECORD_ARTIFACTS_AS_USED_IN_FN_DECL)
	(RECORD_ARTIFACTS_AS_USED_IN_FN_TYPE): Define new macros.
	(build_function_decl, build_var_decl, build_qualified_type_decl)
	(build_pointer_type_def, build_reference_type_def)
	(build_function_type, build_array_type_def, build_enum_type_decl)
	(build_typedef_decl, build_class_decl, build_union_decl): Use the
	macros above to mark the relevant sub-types as used by the
	artifact being built.
	* tools/abilint.cc (struct artifact_use_relation_tree): Define new
	type, guarded by the WITH_SHOW_TYPE_USE_IN_ABILINT macro.
	(fill_artifact_use_tree, build_type_use_tree, emit_trace)
	(emit_artifact_use_trace, emit_artifact_use_trace)
	(show_how_type_is_used): Define static functions guarded by the
	WITH_SHOW_TYPE_USE_IN_ABILINT macro.
	(display_usage): Add doc string for the --show-type-use option,
	guarded by the WITH_SHOW_TYPE_USE_IN_ABILINT macro.
	(parse_command_line): Parse the --show-type-use option, guarded by
	the WITH_SHOW_TYPE_USE_IN_ABILINT macro.
	(main): Slight re-organisation to make the abixml file reading use
	a read_context.  That read context is then used to analyze how a
	given type is used whenever the --show-type-use option is used.
