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

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.
