Rework the directive parsing code. Instead of using a lot of strcmp()s

2005-04-11T07:20:10Z

on every line that starts with a dot use a minimal perfect hash function and a single strcmp() on the first word after the dot to find out whether it is really a directive call and, if yes, which one. Then directly dispatch to a handler function for that directive (or fall through to the dependency handling code). This makes the directive parse a little bit more strict about the syntax: the directive word must be followed by a character that is not alphanumerical and not an underline (making .undefFOO illegal); .endif and .else can only be followed by comments.
