bit_util: Add fls_ functions; "find last set".
...
These simplify a lot of the bit_util module, which had grown bits and pieces of
this functionality across a variety of places over the years.
While we're here, kill off BIT_UTIL_INLINE and don't do reentrancy testing for
bit_util.

bit_util: Change ffs functions indexing.

Making these 0-based instead of 1-based makes calling code simpler and will be
more consistent with functions introduced in subsequent diffs.

For now, this is just a stub containing the ecaches, with no surrounding code
changed. Eventually all the core allocator bits will be moved in, in the
subsequent stack of commits.

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.)
