9b5d105fc3 Emap: Move in iealloc. 
This is logically scoped to the emap.

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.

used outside of the emap module.

ba0e35411c Rework the bin locking around tcache refill / flush. 
Previously, tcache fill/flush (as well as small alloc/dalloc on the arena) may
potentially drop the bin lock for slab_alloc and slab_dalloc.  This commit
refactors the logic so that the slab calls happen in the same function / level
as the bin lock / unlock.  The main purpose is to be able to use flat combining
without having to keep track of stack state.

In the meantime, this change reduces the locking, especially for slab_dalloc
calls, where nothing happens after the call.

97dd79db6c Implement deallocation events. 
Make the event module to accept two event types, and pass around the event
context.  Use bytes-based events to trigger tcache GC on deallocation, and get
rid of the tcache ticker.

88d9eca848 Enforce page alignment for sampled allocations. 
This allows sampled allocations to be checked through alignment, therefore
enable sized deallocation regardless of cache_oblivious.

38a48e5741 Set reentrancy to 1 for tsd_state_purgatory. 
Reentrancy is already set for other non-nominal tsd states (reincarnated and
minimal_initialized).  Add purgatory to be safe and consistent.

88b0e03a4e Implement opt.stats_interval and the _opts options. 
Add options stats_interval and stats_interval_opts to allow interval based stats
printing.  This provides an easy way to collect stats without code changes,
because opt.stats_print may not work (some binaries never exit).

6342da0970 Ehooks: Further optimize default merge case. 
This avoids the cost of an iealloc in cases where the user uses the default
merge hook without using the default extent hooks.

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.

576d7047ab Ecache: Should know its arena_ind. 
What we call an arena_ind is really the index associated with some particular
set of ehooks; the arena is just the user-visible portion of that.  Making this
explicit, and reframing checks in terms of that, makes the code simpler and
cleaner, and helps us avoid passing the arena itself all throughout extent code.

This lets us put back an arena-specific assert.

57fe99d4be Move relevant index into the ehooks_t itself. 
It's always passed into the ehooks; keeping it colocated lets us avoid passing
the arena everywhere.

c792f3e4ab edata_cache: Remember the associated base_t. 
This will save us some trouble down the line when we stop passing arena pointers
everywhere; we won't have to pass around a base_t pointer either.
