'M-x package-install' installs a package if it's not already installed.

See above.

It also _can_ install a newer version of the package if the first 
argument is of type 'package-desc', but that's basically an internal 
overload, not something that can be user interactively, or easily in the 
init script. BTW, the value of package-install-upgrade-built-in has no 
effect on that "overload".
