7e6c8a7286 Emap: Standardize naming. 
Namespace everything under emap_, always specify what it is we're looking up
(emap_lookup -> emap_edata_lookup), and use "ctx" over "info".

ac50c1e44b Emap: Remove direct access to emap internals. 
In the process, we do a few local cleanups and optimizations.  In particular,
the size safety check on tcache flush no longer does a redundant load.

06e42090f7 Make jemalloc.c use the emap interface. 
While we're here, we'll also clean up some style nits.

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.

08eb1e6c31 Emap: Comments and cleanup 
Document some of the public interface, and hide the functions that are no longer
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.
