stdioext OpenVMS patch.

[John E. Malmberg]

On OpenVMS, the struct _iobuf is needed to access members of the struct
FILE.

This is a patch for the affected stdioext modules to compile on OpenVMS.

The approach looks generally right, but I'd request a couple of changes
before this can go in:

* Is _IOERR defined on OpenVMS? In some files, you treat OpenVMS
as part of the _IOERR case, in others you do it before _IOERR. Which
is not consistent.
If _IOERR is defined on OpenVMS, please update all
#elif defined _IOERR /* AIX, HP-UX, IRIX, OSF/1, Solaris, OpenServer, mingw, MSVC, NonStop Kernel */
lines to include OpenVMS at the end of the comment.

* Instead of defining a variable 'stream', please using the same coding
style as for the other platforms: use macro fp_ which is defined to
a cast expression through lib/stdio-impl.h.

* The fbufmode.c change has a regression for all non-Windows, non-OpenVMS
platforms.

* The freading.c change is misindented.

Thank you. That greatly simplifies the updated attached patch.

Reverted back to original code.

No longer applicable.

Thanks. Applied (with comment changes also in fflush.c, fseeko.c).
