Lispequ.lisp patches

[Ranson <ranson@lannion.cnet.fr>]

I have found that after applying the p1/p2 patch to lispequ.lisp, the file
is no longer compilable (well, neither it is before...). I have applied
the following changes to the source, that make the file compilable and
loadable. I hope I didn't break anything:
- Move the definitions of $t_vector and $t_lfun before their first respec-
tive reference.
- Replace the occurrence of #.$v_data by $v_data.
