PR mi/14741:
	* mi/mi-cmd-var.c (varobj_update_one): Take value of
	attribute "dynamic" and "displayhint" from printed child,
	not the root variable.

	* gdb.python/py-mi.exp: Correct expected results for attribute
	"dynamic" returned by -var-update.
	Add test case for correct handling of "diplayhint" for children
	of dynamic varobjs.
	* gdb.python/py-prettyprint.c (set_itme): New function.
	(bug_14741) New function.
	(main) Add call to bug_14741().
	* gdb.python/py-prettyprint.py (class ArrayPrinter): New class.
