ENHANCED: partial_string/3 no longer creates atoms
...
As a consequence, resulting strings are now quickly reclaimed on
backtracking.
This addresses #2912 .
Test case:
:- use_module(library(iso_ext)).
:- use_module(library(lists)).
ab(a).
ab(b).
Sample query:
?- length(Ls, 1_000_000),
maplist(ab, Ls),
partial_string(Ls, Es0, []),
Es0 == Ls.
Ls = "aaaaaaaaaaaaaaaaaaa ...", Es0 = "aaaaaaaaaaaaaaaaaaa ..."
; Ls = "aaaaaaaaaaaaaaaaaaa ...", Es0 = "aaaaaaaaaaaaaaaaaaa ..."
; Ls = "aaaaaaaaaaaaaaaaaaa ...", Es0 = "aaaaaaaaaaaaaaaaaaa ..."
; Ls = "aaaaaaaaaaaaaaaaaaa ...", Es0 = "aaaaaaaaaaaaaaaaaaa ..."
; Ls = "aaaaaaaaaaaaaaaaaaa ...", Es0 = "aaaaaaaaaaaaaaaaaaa ..."
; ... .
running in constant memory.

Fix allocate_pstr randomly refusing to properly allocate memory
...
This one was a toughie: it turns out that using `ptr::align_of()`` was
a bad idea, since the buffer in `Heap` itself is not aligned to
`Heap::heap_cell_alignment()`, so `ptr::align_of()` would sometimes
return lower values than expected.
That made for an heisenbug: if the alignment of the heap happened to be 4,
then the bug wouldn't trigger.
