Commit the flex output into revision control, for the benefit of those
without flex or with only very old flex. This change is split into a
separate patch for ease of review. Generated with flex 2.5.35-6 on
Debian lenny i386, by running "make" in the libxl directory. No
manual changes in this commit.
