jilles 129853101d 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.

# This file lists all the builtin commands. The first column is the name
# of a C routine.
# The -j flag specifies that this command is to be excluded from systems
# without job control.
# The -h flag specifies that this command is to be excluded from systems
# based on the NO_HISTORY compile-time symbol.
# The -s flag specifies that this is a POSIX 'special built-in' command.
# The rest of the line specifies the command name or names used to run the
# command. The entry for bltincmd, which is run when the user does not specify
# a command, must come first.
#
# NOTE: bltincmd must come first!
