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.

1d449bd9a6 Emap: Internal rtree context setting. 
The only time sharing an rtree context saves across extent operations isn't a
no-op is when tsd is unavailable.  But this happens only in situations like
thread death or initialization, and we don't care about shaving off every
possible cycle in such scenarios.

231d1477e5 Rename emap_split_prepare_t -> emap_prepare_t.

e210ccc57e Move extent2 -> extent. 
Eventually, we may fully break off the extent module; but not for some time.  If
it's going to live on in a non-transitory state, it might as well have the nicer
name.

865debda22 Rename extent.h -> edata.h. 
This name is slightly pithier; a full-on rename will come shortly.

92a511d385 Make extent module hermetic. 
In the form of extent2.h.  The naming leaves something to be desired, but I'll
leave that for a later diff.

e08c581cf1 Extent: Get rid of extent-specific pre/post reentrancy calls. 
These are taken care of by the ehook module; the extra increments and
decrements are safe but unnecessary.

9f6eb09585 Extents: Eagerly initialize extent hooks. 
When deferred initialization was added, initializing required copying
sizeof(extent_hooks_t) bytes after a pointer chase. Today, it's just a single
pointer loaded from the base_t. In subsequent diffs, we'll get rid of even that.

41187bdfb0 Extents: Break extent-struct/arena interactions 
Specifically, the extent_arena_[g|s]et functions and the address randomization.

These are the only things that tie the extent struct itself to the arena code.

c9cdc1b27f Limit to exact fit on Windows with retain off. 
W/o retain, split and merge are disallowed on Windows.  Avoid doing first-fit
which needs splitting almost always.  Instead, try exact fit only and bail out
early.

4e36ce34c1 Track the leaked VM space via the abandoned_vm counter. 
The counter is 0 unless metadata allocation failed (indicates OOM), and is
mainly for sanity checking.
