This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Add a new getty/gettytab capability to generate an initial message dynamically. This modification adds a new gettytab(5) option (iM) to specify a program to run that will generate the initial (banner) message that is displayed before the login prompt. Such a capability is useful when dynamic information is needed in the banner message that cannot be supplied by the set of % substitution sequences available in the "im" option.
