When used as a shell builtin, this program decoded a subset of arguments
known to printf(3) and then used printf() to format it... The only
problem what the #define printf out1fmt. The code was behaving differently
when run as a shell builtin since out1fmt() isn't printf(3).

Simple hack. Print to a buffer and fputs (also #defined for sh) the
result. This should fix the printf builtin problem in PR#1673, rather
than leaving the call commented out. (printf.o was being statically linked
in anyway, we might as well use it)

Move out some of the shell builtin bogosity from printf's source to
sh's builtin/bltin.h.

Remove trailing whitespace.

Make the syntax checks for the format string more strict. The string
"%8*s" is no longer considered to be a valid format description.

This closes PR bin/386.

POSIX says that octal escapes have the format \ddd in the format string,
but \0ddd in a %b argument, with a length restriction of 3 octal digits
in either case. This seems silly, but it needs to be right so it's possible
to write an octal escape followed by an ordinary digit. Solaris printf(1)
and GNU printf(1) also behave this way.

Example: "printf '\0752'" now produces "=2" instead of garbage.

Prefer {u,}intmax_t over the deprecated {u_,}quad_t.

Sync program's usage() with manpage's SYNOPSIS.

Handle null characters in the format string. A \0 in the argument passed to %b
still results in trucation but this is be much harder to fix.

No reason to write \a and \v as octal escape sequences.

- Move parts of the long main() function into a new function doformat().
- Rewrite the loop in main() to be more understandable.

Assign 0.0 to the variable passed to getfloating() if the argument is missing.

Replace buggy for-loops to skip certain character with strspn(). If *fmt was
'\0' (eg in the invocation 'printf %'), the for-loop would miss the terminating
null character.
