bf55e58e63 Rename test/unit/decay -> test/unit/arena_decay.
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.

3192d6b77d Extents: Have extent_dalloc_gap take ehooks.
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.

356aaa7dc6 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).

585f925055 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.

c9d56cddf2 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.)

change settings set by the configuration system itself.

2e5899c129 Stats: Fix tcache_bytes reporting.
Previously, large allocations in tcaches would have their sizes reduced during
stats estimation.  Added a test, which fails before this change but passes now.

This fixes a bug introduced in 5934846612, which
was itself fixing a bug introduced in 9c0549007d.
