Redo r52569 in a way that doesn't break the GUI. Add a mem_pool member to

tree_data and reference it directly when allocating/freeing tree items. This
lets us keep multiple around when we need them, and still lets us use
wmem_free_all for a major speedup. It also, coincidentally, lets us get rid of
the annoying fi_tmp hack that was needed before, since that element gets swept
up in the free_all with everything else.

Keep one pool cached to avoid creating/destroying a pool for each packet,
another minor performance win.

The various changes in approach seem to balance out pretty much exactly, this
still gives ~11% over pre-52569.
