This is really more of an end-to-end test at the arena level; it's not just of
the decay code in particular any more.

We're almost to the point where the extent code doesn't know about arenas at
all. In that world, we shouldn't pull them out of the arena.

Introduce lockedint module.
...
This pulls out the various abstractions where some stats counter is sometimes an
atomic, sometimes a plain variable, sometimes always protected by a lock,
sometimes protected by reads but not writes, etc. With this change, these cases
are treated consistently, and access patterns tagged.
In the process, we fix a few missed-update bugs (where one caller assumes
"protected-by-a-lock" semantics and another does not).

Move cache index randomization out of extent.
...
This is logically at a higher level of the stack; extent should just allocate
things at the page-level; it shouldn't care exactly why the callers wants a
given number of pages.

Optimize meld in qr module
...
The goal of `qr_meld()` is to change the following four fields
`(a->prev, a->prev->next, b->prev, b->prev->next)` from the values
`(a->prev, a, b->prev, b)` to `(b->prev, b, a->prev, a)`.
This commit changes
```
a->prev->next = b;
b->prev->next = a;
temp = a->prev;
a->prev = b->prev;
b->prev = temp;
```
to
```
temp = a->prev;
a->prev = b->prev;
b->prev = temp;
a->prev->next = a;
b->prev->next = b;
```
The benefit is that we can use `b->prev->next` for `temp`, and so
there's no need to pass in `a_type`.
The restriction is that `b` cannot be a `qr_next()` macro, so users
of `qr_meld()` must pay attention. (Before this change, neither `a`
nor `b` could be a `qr_next()` macro.)
