Update.
* libio/iofopncook.c (_IO_cookie_seekoff): Define. Mark offset as
invalid to disable optimizations in fileops which won't work here.
(_IO_cookie_jumps): Use it.
(_IO_old_cookie_jumps): Likewise.
* libio/fmemopen.c (fmemopen_seek): Result must be returned in *P,
not the return value.
* stdio-common/Makefile (tests): Add tst-fmemopen2.
* stdio-common/tst-fmemopen2.c: New file.
