[BZ #1996]
* libio/memstream.c (open_memstream): Allocate initial buffer with
calloc.
* libio/wmemstream.c (open_wmemstream): Likewise.
* 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/wstrops.c: Likewise.
* libio/vasprintf.c: Add comment as to why we do not have to use
calloc instead of malloc to allocate initial buffer.
* libio/Makefile (tests): Add bug-memstream1 and bug-wmemstream1.
* libio/bug-memstream1.c: New file.
* libio/bug-wmemstream1.c: New file.
