aa8b280f1c adjust the splay tree implementation so that it creates fewer cons 
cells when searching in the tree

Two tricks: represent lists of nodes as improper lists so singleton
lists don't allocate a cons and pass around two accumulators that
correspond to the hd & tl of a path, instead of cons'ing that up
into a list and them immediately taking it apart again

measurement: when starting up drracket with
collects/drracket/private/unit.rkt and then waiting for the colorer to
finish, and then inserting an open quote right before the first open
quote in the file (and waiting again for the colorer to finish)
creates 249000 cons cells before this change and 116000 after this
change

After a little more work, I'm pretty much convinced that this was
the wrong approach and that the splaying implementation should just
change to not allocate the paths into lists at all, thus removing
the other 116k cons cells. (I plan to get to this another day;
it should not be difficult now that I roughly understand how these
things work.)

I also looked into top-down splaying and found these notes to
be illuminating:

  http://digital.cs.usu.edu/~allan/DS/Notes/Ch22.pdf

They essentially convinced me that we cannot use top-down splaying
here, since the "reassembling" stage requires moving some arbitrary,
unexplored subtree from a right-child to a left-child, and thus the
left-subtree-length cannot be updated properly.

11994bd4f8 fix a bug in the module lexer; it was returning the wrong length for the tokens 
it creates when the #lang line isn't well-formed (eg "#lang racke").

65fd0234ad add a unicode test to scheme-lexer.rkt 
and change the tests so they all run with port line
counting enabled (or else the unicode test fails)

adjust module-lexer.rkt tests so they can run in either
port-counting mode or not (but currently run them all in
port-counting mode because scheme-lexer doesn't work without it)

also make a first stab at what needs to change in the module
lexer to make it work in non port line-counting mode

1eaf53d4cb adjust the module lexer so that it treats the entire range that 
'read-language' uses as a single token in the case that read-language
fails. This helps it to deal with things like s-exp and at-exp
properly
