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.

9cad5639ff Ehooks: remove arena_ind parameter. 
This lives within the ehooks_t now, so that callers don't need to know it.

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.

ae23e5f426 Unify extent_alloc_wrapper with the other wrappers. 
Previously, it was really more like extents_alloc (it looks in an ecache for an
extent to reuse as its primary allocation pathway).  Make that pathway more
explciitly like extents_alloc, and rename extent_alloc_wrapper_hard accordingly.

bb70df8e5b Extent refactor: Introduce ecache module. 
This will eventually completely wrap the eset, and handle concurrency,
allocation, and deallocation.  For now, we only pull out the mutex from the
eset.

a7862df616 Rename extent_t to edata_t. 
This frees us up from the unfortunate extent/extent2 naming collision.

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

a738a66b5c Ehooks: Add some debug zero and addr checks. 
These help make sure that the ehooks return properly zeroed memory when required
to.

4b2e5ee8b9 Ehooks: Add a "zero" ehook. 
This is the first API expansion.  It lets the hooks pick where and how to purge
within themselves.

403f2d1664 Extents: Split out introspection functionality. 
This isn't really part of the core extent allocation facilities.  Especially as
this module grows, having it in its own place may come in handy.

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.

703fbc0ff5 Introduce unsafe reentrancy guards. 
We have to work to circumvent the safety checks in pre_reentrancy when going
down extent hook pathways.  Instead, let's explicitly have checked and unchecked
guards.

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.

4278f84603 Move extent hook getters/setters to arena.c 
This is where they're logically scoped; they access arena data.

d5031ea824 Allow dallocx and sdallocx after tsd destruction. 
After a thread turns into purgatory / reincarnated state, still allow dallocx
and sdallocx to function normally.

4afd709d1f Restructure setters for profiling info 
Explicitly define three setters:

- `prof_tctx_reset()`: set `prof_tctx` to `1U`, if we don't know in
advance whether the allocation is large or not;
- `prof_tctx_reset_sampled()`: set `prof_tctx` to `1U`, if we already
know in advance that the allocation is large;
- `prof_info_set()`: set a real `prof_tctx`, and also set other
profiling info e.g. the allocation time.

Code structure wise, the prof level is kept as a thin wrapper, the
large level only provides low level setter APIs, and the arena level
carries out the main logic.

dd649c9485 Optimize away the tsd_fast() check on fastpath. 
Fold the tsd_state check onto the event threshold check.  The fast threshold is
set to 0 when tsd switch to non-nominal.

The fast_threshold can be reset by remote threads, to refect the non nominal tsd
state change.
