Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Add parameterized position handling to printf(1).

Add a new %n$ option to change the order of the parameters as
done in the ksh93 builtin printf (among others).

For example:
%printf '%2$1d %1$s\n'

printf(1): Document that %c and precision for %b/%s use bytes, not chars.

This means these features do not work as expected with multibyte characters.

This perhaps less than ideal behaviour matches

printf(1): Document that %c and precision for %b/%s use bytes, not chars.

This means these features do not work as expected with multibyte characters.

This perhaps less than ideal behaviour matches printf(3) and is specified by
POSIX.

printf: Allow multibyte characters for '<char> form, avoid negative codes.

Examples:
LC_ALL=en_US.UTF-8 printf '%d\n' $(printf \'\\303\\244)
LC_ALL=en_US.ISO8859-1 printf '%d\n' $(printf \'\\344

printf: Allow multibyte characters for '<char> form, avoid negative codes.

Examples:
LC_ALL=en_US.UTF-8 printf '%d\n' $(printf \'\\303\\244)
LC_ALL=en_US.ISO8859-1 printf '%d\n' $(printf \'\\344)
Both of these should print 228.

Like some other shells, incomplete or invalid multibyte characters yield the
value of the first byte without a warning.

Note that there is no general way to go back from the character code to the
character.

sh: Add printf builtin.

This was removed in 2001 but I think it is appropriate to add it back:
* I do not want to encourage people to write fragile and non-portable echo
commands by making printf much slower than echo.
* Recent versions of Autoconf use it a lot.
* Almost no software still wants to support systems that do not have
printf(1) at all.
* In many other shells printf is already a builtin.

Side effect: printf is now always the builtin version (which behaves
identically to /usr/bin/printf) and cannot be overridden via PATH (except
via the undocumented %builtin mechanism).

Code size increases about 5K on i386. Embedded folks might want to replace
/usr/bin/printf with a hard link to /usr/bin/alias.
