Add helpers to add and remove actx entries. (see #3728)

Use the helper in compose update_idx(), to consolidate the resize
logic and simplify the code.

Separate out the actx "free" routine from a routine to empty out the
idx.  The index regeneration routines should flush and rebuild the
index without having to renerate the actx structure.
