* libc/include/stdio.h: Add new iprintf and iscanf variants. Also
do some reordering.
* libc/machine/powerpc/vfscanf.c: Remove __sccl function.
* libc/stdio/Makefile.am: Add support for new iprintf and iscanf
family functions.
* libc/stdio/Makefile.in: Regenerated.
* libc/stdio/fiprintf.c: Remove doc to siprintf.c.
* libc/stdio/iprintf.c: Ditto.
* libc/stdio/local.h (__svfiscanf_r): New prototype.
* libc/stdio/siprintf.c: Add docs for various iprintf family functions.
* libc/stdio/sniprintf.c: Move docs to siprintf.c.
* libc/stdio/stdio.tex: Add new functions.
* libc/stdio/vfscanf.c: Split out __sccl function to separate
file and add special name defines so this file can be used
to build vfiscanf.o.
* libc/stdio/asiprintf.c: New file.
* libc/stdio/fiscanf.c: Ditto.
* libc/stdio/iscanf.c: Ditto.
* libc/stdio/sccl.c: Ditto.
* libc/stdio/siscanf.c: Ditto.
* libc/stdio/vasiprintf.c: Ditto.
* libc/stdio/viprintf.c: Ditto.
* libc/stdio/viscanf.c: Ditto.
