PATCH: change splay_tree_key & splay_tree_value types to void*

[Greg McGary]

Splay trees with string keys & values need to store bounds,
so a `long' doesn't do the job.  I changed `long' to `void*',
but that might be too naive if GCC supports architectures
for which sizeof (long) > sizeof (void*).  If we need
to handle that, then I guess we should make these types
unions.

Anyway, this works fine, and causes no build or testsuite regressions
on conventional 32-bit architectures.
