* 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.

DESCRIPTION
<<fiprintf>> is a restricted version of <<fprintf>>: it has the same

formatting---the <<f>>, <<g>>, <<G>>, <<e>>, and <<F>> type specifiers
are not recognized.
RETURNS
<<fiprintf>> returns the number of bytes in the output string,
save that the concluding <<NULL>> is not counted.
<<fiprintf>> returns when the end of the format string is
encountered. If an error occurs, <<fiprintf>>
returns <<EOF>>.
PORTABILITY
<<fiprintf>> is not required by ANSI C.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,

DESCRIPTION DESCRIPTION

arguments and behavior, save that it cannot perform any floating-point <<asiprintf>>, are the same as <<printf>>, <<fprintf>>,
formatting: the <<f>>, <<g>>, <<G>>, <<e>>, and <<F>> type specifiers <<sprintf>>, <<snprintf>>, and <<asprintf>>, respectively,
are not recognized. only that they restrict usage to non-floating-point format
specifiers.
RETURNS RETURNS
<<siprintf>> returns the number of bytes in the output string, <<siprintf>> and <<asiprintf>> return the number of bytes in the output string,
save that the concluding <<NULL>> is not counted. save that the concluding <<NULL>> is not counted.
<<siprintf>> returns when the end of the format string is <<iprintf>> and <<fiprintf>> return the number of characters transmitted.
encountered. If an error occurs, <<iprintf>> and <<fiprintf>> return <<EOF>> and
<<asiprintf>> returns -1. No error returns occur for <<siprintf>>.
PORTABILITY PORTABILITY

DESCRIPTION
<<iscanf>>, <<fiscanf>>, and <<siscanf>> are the same as
<<scanf>>, <<fscanf>>, and <<sscanf>> respectively, only that
they restrict the available formats to non-floating-point
format specifiers.
The routines <<_iscanf_r>>, <<_fiscanf_r>>, and <<_siscanf_r>> are reentrant
versions of <<iscanf>>, <<fiscanf>>, and <<siscanf>> that take an additional
first argument pointing to a reentrancy structure.
RETURNS
<<iscanf>> returns the number of input fields successfully
scanned, converted and stored; the return value does
not include scanned fields which were not stored.
If <<iscanf>> attempts to read at end-of-file, the return
value is <<EOF>>.
If no fields were stored, the return value is <<0>>.
PORTABILITY
<<iscanf>>, <<fiscanf>>, and <<siscanf>> are newlib extensions.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

DESCRIPTION
<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>> and
<<vsniprintf>> are (respectively) variants of <<iprintf>>, <<fiprintf>>,
<<asiprintf>>, <<siprintf>>, and <<sniprintf>>. They differ only in
restricting the caller to use non-floating-point format specifiers.
RETURNS
The return values are consistent with the corresponding functions:
<<vasiprintf>>/<<vsiprintf>> returns the number of bytes in the output string,
save that the concluding <<NULL>> is not counted.
<<viprintf>> and <<vfiprintf>> return the number of characters transmitted.
If an error occurs, <<viprintf>> and <<vfiprintf>> return <<EOF>> and
<<vasiprintf>> returns -1. No error returns occur for <<vsiprintf>>.
PORTABILITY
<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>> and <<vsniprintf>>
are newlib extensions.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

DESCRIPTION
<<viscanf>>, <<vfiscanf>>, and <<vsiscanf>> are (respectively) variants
of <<iscanf>>, <<fiscanf>>, and <<siscanf>>. They differ only in
allowing their caller to pass the variable argument list as a
<<va_list>> object (initialized by <<va_start>>) rather than
directly accepting a variable number of arguments.
RETURNS
The return values are consistent with the corresponding functions:
<<viscanf>> returns the number of input fields successfully scanned,
converted, and stored; the return value does not include scanned
fields which were not stored.
If <<viscanf>> attempts to read at end-of-file, the return value
is <<EOF>>.
If no fields were stored, the return value is <<0>>.
The routines <<_viscanf_r>>, <<_vfiscanf_f>>, and <<_vsiscanf_r>> are
reentrant versions which take an additional first parameter which points to the
reentrancy structure.
PORTABILITY
These are newlib extensions.
Supporting OS subroutines required:

DESCRIPTION
<<vsniprintf>> is a restricted version of <<vsnprintf>>: it has the same
arguments and behavior, save that it cannot perform any floating-point
formatting: the <<f>>, <<g>>, <<G>>, <<e>>, and <<F>> type specifiers
are not recognized.
RETURNS
<<vsniprintf>> returns the number of bytes in the output string,
save that the concluding <<NULL>> is not counted.
<<vsniprintf>> returns when the end of the format string is
encountered.
PORTABILITY
<<vsniprintf>> is not required by ANSI C.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
