a0c1f4ac57 Rtree: take the base allocator as a parameter. 
This facilitates better testing by avoiding mixing of the "real" base with the
base used by the rtree under test.

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.

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.

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).

6a622867ca Add "thread.idle" mallctl. 
This can encapsulate various internal cleaning logic, and can be used to free up
resources before a long sleep.

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.

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.

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.

b55419f9b9 Restructure profiling 
Develop new data structure and code logic for holding profiling
related information stored in the extent that may be needed after the
extent is released, which in particular is the case for the
reallocation code path (e.g. in `rallocx()` and `xallocx()`).  The
data structure is a generalization of `prof_tctx_t`: we previously
only copy out the `prof_tctx` before the extent is released, but we
may be in need of additional fields. Currently the only additional
field is the allocation time field, but there may be more fields in
the future.

The restructuring also resolved a bug: `prof_realloc()` mistakenly
passed the new `ptr` to `prof_free_sampled_object()`, but passing in
the `old_ptr` would crash because it's already been released.  Now
the essential profiling information is collectively copied out early
and safely passed to `prof_free_sampled_object()` after the extent is
released.
