Switch from libcollections to liballoc (gated on an "alloc" feature)
...
libcollections was recently merged into liballoc:
https://github.com/rust-lang/rust/pull/42648
I went ahead and also added an "alloc" feature which no_std users can use to opt
into liballoc features (i.e. any code using Vec). This should have no effect on
anything but no_std usage. It does make it possible for people without
allocators to use curve25519-dalek if they want though. Might be nice for
"bare metal" development.
All that said, from what I can gather liballoc, while not "stable", should
likely stick around for the forseeable future.
Some backstory on the liballoc/libcollections merge here:

It's already obvious that it's constant-time because it's in the subtle

Being able to do `P * s`, but not `s * P`, is slightly annoying, particularly
with longer equations when it is desired to be able to glance at the maths and
see that the code is the same.
Now either syntax is allowed.
