Convert libc/stdio from K&R to ANSI C

And add '__restrict' where it appeared in the header prototypes

Renumber clauses to reduce diffs to other versions

2013-04-23T13:33:13+00:00

NetBSD, OpenBSD, and Android's Bionic all number the clauses 1 through 3,
so follow suit to make comparison easier.

# If I've done so improperly on a file, please let me know.

Rename cantwrite() to prepwrite(). The latter is less confusing,

2004-06-08T05:45:48+00:00

since the macro isn't really a predicate, and it has side-effects.
Also, don't set errno if prepwrite() fails, since this is done in
prepwrite() now.

If handed a file pointer we can't write to, set errno properly to EBADF

in order to get SUSv2 conformant behavior in higher level calls like
fputs() and puts().

I believe have made all of libc .c's as consistent as possible.

Re-arrange my funopen(3) fix to minimize differences with original stdio code,

Add fp->_offset optimization in _SAPP+_SOPT case

Move all stdio internal flags processing and setting out of __sread(),

2001-09-02T19:10:10+00:00

__swrite() and __sseek() to higher level. According to funopen(3) they all
are just wrappers to something like standard read(2), write(2) and
lseek(2), i.e. must not touch stdio internals because they are replaceable
with any other functions knows nothing about stdio internals. See example
of funopen(3) usage in sendmail sources f.e.

NOTE: this is original stdio bug, not result of my range checkin added.
