This takes another small step towards disentangling the build system from the old AT&T environment. The USAGE_LICENSE macros with author and copyright information, which was formerly generated dynamically for each file from a database, are eliminated and the copyright/author information is instead inserted into the AST getopt usage strings directly. Repetitive license/copyright information is also removed from the getopt strings in the builtin commands (src/lib/libcmd/*.c and src/cmd/ksh93/data/builtins.c). There's no need to include 55 identical license/copyright strings in the ksh binary; one (in the main ksh getopt string, shown by ksh --man) ought to be enough! This makes the ksh binary about 10k smaller. It does mean that something like 'enum --author', 'typeset --license' or 'shift --copyright' will now not show those notices for those builtins, but I doubt anyone will care.
