til_tap: convert taps to intrusive public structs

The previous commit implemented taps in a way requiring
allocations and cleanup.  Let's experiment a bit and just make
them absolutely minimal named typed variable+indirection
bindings.

The helpers are retained, but converted to initializers rather
than new() style constructors.  They provide type-checking of the
variable and indirection pointer, and prevent incorrect TIL_TYPE
values going in til_type_t.type for the supplied bound
elems+ptr.
