tlist.h:
Change interface to allow storing of handle address in timer structure.
aispoll.h, aispoll.c:
Change define for timer handle.
tlist.c:
Store handle address in timer structure. When timer expires, wipe
out the handle address's value, since the timer is no longer valid.
This allows double frees, or frees on handles that haven't been
added.
One note of caution: a handle cannot be moved into another variable
and be expected to work properly for double frees.
