[PATCH v2 1/5] Pre-cleanup: Remove unnecessary redefinitions of std symbols.

[Zack Weinberg]

Two files in stdio-common were unnecessarily redefining some standard
symbols as their _IO_ aliases, which causes problems for a build with
the visibility of libio.h reduced.

This changes installed stripped libraries, because the line numbering
changes in vfprintf.c, which changes the messages associated with a
bunch of assertions.  However, if it weren't entangled with a scary
change I wouldn't be hesitating to call it an obvious cleanup.

	* stdio-common/vfprintf.c: Don't redefine FILE, va_list, or BUFSIZ.
        * stdio-common/tstgetln.c: Don't redefine ssize_t.
