Cleanup of redundant/useless header file inclusion.
ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
/*
* This is a comment.
*/
Changed syntax of grant/deny statements so they now must be inside an
'update-policy' block.
quote rr types when printing grant/deny statements as they can
clash with config file keywords.
Added rcs Id inside comment.
