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.

b14fdaaca0 Add a missing prof_alloc_rollback() call. 
In the case where prof_alloc_prep() is called with an over-estimate of
allocation size, and sampling doesn't end up being triggered, the tctx
must be discarded.

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.

db72272bef Use rtree-based chunk lookups rather than pointer bit twiddling. 
Look up chunk metadata via the radix tree, rather than using
CHUNK_ADDR2BASE().

Propagate pointer's containing extent.

Minimize extent lookups by doing a single lookup (e.g. in free()) and
propagating the pointer's extent into nearly all the functions that may
need it.

2d2b4e98c9 Add element acquire/release capabilities to rtree. 
This makes it possible to acquire short-term "ownership" of rtree
elements so that it is possible to read an extent pointer *and* read the
extent's contents with a guarantee that the element will not be modified
until the ownership is released.  This is intended as a mechanism for
resolving rtree read/write races rather than as a way to lock extents.
