ptrlist: make linearize_ptr_list() generic
The ptrlist API has a function to copy the elements of a ptrlist
into an array but it's not typed and thus needs a wrapper (or casts)
for each type it's used for. Also, 'linearize' is confusing since
this is unrelated to Sparse's linearization.
Simplify this by adding a generic (but type-safe) macro for this
with a more descriptive name: ptr_list_to_array()
