cc289f40b6 Propagate tsdn to default extent hooks. 
This avoids bootstrapping issues for configurations that require
allocation during tsd initialization.

This resolves #390.

02a475d89a Use extent_commit_wrapper() rather than directly calling commit hook. 
As a side effect this causes the extent's 'committed' flag to be
updated.

487093d999 Fix regressions related extent splitting failures. 
Fix a fundamental extent_split_wrapper() bug in an error path.

Fix extent_recycle() to deregister unsplittable extents before leaking
them.

Relax xallocx() test assertions so that unsplittable extents don't cause
test failures.

9a645c612f Fix an extent [de]allocation/[de]registration race. 
Deregister extents before deallocation, so that subsequent
reallocation/registration doesn't race with deregistration.

4e910fc958 Fix extent_alloc_dss() regressions. 
Page-align the gap, if any, and add/use extent_dalloc_gap(), which
registers the gap extent before deallocation.

c4bb17f891 Fix gdump triggering regression. 
Now that extents are not multiples of chunksize, it's necessary to track
pages rather than chunks.

f8f0542194 Modify extent hook functions to take an (extent_t *) argument. 
This facilitates the application accessing its own extent allocator
metadata during hook invocations.

This resolves #259.

6f29a83924 Add rtree lookup path caching. 
rtree-based extent lookups remain more expensive than chunk-based run
lookups, but with this optimization the fast path slowdown is ~3 CPU
cycles per metadata lookup (on Intel Core i7-4980HQ), versus ~11 cycles
prior.  The path caching speedup tends to degrade gracefully unless
allocated memory is spread far apart (as is the case when using a
mixture of sbrk() and mmap()).

819417580e Fix rallocx() sampling code to not eagerly commit sampler update. 
rallocx() for an alignment-constrained request may end up with a
smaller-than-worst-case size if in-place reallocation succeeds due to
serendipitous alignment.  In such cases, sampling may not happen.

d28e5a6696 Improve interval-based profile dump triggering. 
When an allocation is large enough to trigger multiple dumps, use
modular math rather than subtraction to reset the interval counter.
Prior to this change, it was possible for a single allocation to cause
many subsequent allocations to all trigger profile dumps.

When updating usable size for a sampled object, try to cancel out
the difference between LARGE_MINCLASS and usable size from the interval
counter.
