Subject: libc/misc/gnu/obprintf.c: implement obstack_printf and
 obstack_vprintf

This adds a straight forward implementation for obstack_printf and
obstack_vprintf on uClibc's already existing obstack_grow and
vasprintf.  It does not attempt to port over glibc's implementation
in terms of _IO_* structs and functions.
