	* libio/memstream.c (open_memstream): Allocate initial buffer with
	calloc.

	* libio/strops.c: Pretty printing.
	(_IO_str_overflow): Clear uninitialized part of the new buffer.
	(enlarge_userbuf): New function.
	(_IO_str_seekoff): Call it if seek position is larger than current
	buffer.

	* libio/vasprintf.c: Add comment as to why we do not have to use
	calloc instead of malloc to allocate initial buffer.
