397da03865 Cache bin: rewrite to track more state. 
With this, we track all of the empty, full, and low water states together.  This
simplifies a lot of the tracking logic, since we now don't need the
cache_bin_info_t for state queries (except for some debugging).

44529da852 Cache-bin: Make flush modifications internal 
I.e. the tcache code just calls a cache-bin function to finish flush (and move
pointers around, etc.).  It doesn't directly access the cache-bin's owned memory
any more.

ff6acc6ed5 Cache bin: simplify names and argument ordering. 
We always start with the cache bin, then its info (if necessary).

e1dcc557d6 Cache bin: Only take the relevant cache_bin_info_t 
Previously, we took an array of cache_bin_info_ts and an index, and dereferenced
ourselves.  But infos for other cache_bins aren't relevant to any particular
cache bin, so that should be the caller's job.

da68f73296 Move percpu_arena_update. 
It's not really part of the API of the arena; it changes which arena we're using
that API on.

909c501b07 Cache_bin: Shouldn't know about tcache. 
Instead, have it take the cache_bin_info_ts to use by pointer.  While we're
here, add a src file for the cache bin.

79f1ee2fc0 Move junking out of arena/tcache code. 
This is debug only and we keep it off the fast path.  Moving it here simplifies
the internal logic.

This never tries to junk on regions that were shrunk via xallocx.  I think this
is fine for two reasons:
- The shrunk-with-xallocx case is rare.
- We don't always do that anyway before this diff (it depends on the opt
  settings and extent hooks in effect).

6c3491ad31 Tcache: Unify bin flush logic. 
The small and large pathways share most of their logic, even if some of the
individual operations are different.  We pull out the common logic into a
force-inlined function, and then specialize twice, once for each value of
"small".

9f4fc27389 Ehooks: Fix a build warning.

a0c1f4ac57 Rtree: take the base allocator as a parameter.

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.
