PR python/10705

	* python/python-internal.h: Add lazy_string_object_type
	definition.
	(create_lazy_string_object, gdbpy_initialize_lazy_string)
	(gdbpy_is_lazystring, gdbpy_extract_lazy_string): Define.
	* python/py-value.c (valpy_lazy_string): New function.
	(convert_value_from_python): Add lazy string conversion.
	* python/py-prettyprint.c (pretty_print_one_value): Check if
	return is also a lazy string.
	(print_string_repr): Add lazy string printing branch.
	(print_children): Likewise.
	* python/py-lazy-string.c: New file. Implement lazy strings.
	* python/python.c (_initialize_python): Call
	gdbpy_initialize_lazy_string.
	* varobj.c (value_get_print_value): Add lazy string printing
	branch.  Account for encoding.

	* p-lang.h (pascal_printstr);
	* f-lang.c (f_printstr): Likewise.
	* m2-lang.c (m2_printstr): Likewise.
	* objc-lang.c (objc_printstr): Likewise.
	* p-lang.c (pascal_printstr): Likewise.
	* scm-lang.c (scm_printstr): Likewise.
	* c-valprint.c (c_val_print): Update LA_PRINT_STRING call for
	encoding argument.
	* ada-valprint.c (ada_printstr): Likewise.
	* f-valprint.c (f_val_print): Likewise
	* m2-valprint.c (m2_val_print): Likewise.
	* p-valprint.c (pascal_val_print): Likewise.
