[PATCH 0/4] Java: add LAC support

[Akim Demaille]

This series of commits adds LAC support for Java.  I still need to
write some documentation about it, but it should be a good starting
point for Adela to port this into D.

Of course much of the credit should go to Adrian Vogelsgesang, since I
copied his implementation in C++.  And, well, to Joel E. Denny, for
inventing LAC in the first place.

There's one thing I don't understand well in the Java parser, opiniond
would be most welcome!

I used Vector because I don't like having to deal with low-level
components.  Yet YYStack implements the stacks by hand, on top of
arrays.  Why?  Should we never use Vector?  Or always?

Cheers!
