824b947be0 Add (size_t) casts to MALLOCX_ALIGN(). 
Add (size_t) casts to MALLOCX_ALIGN() macros so that passing the integer
constant 0x80000000 does not cause a compiler warning about invalid
shift amount.

This resolves #354.

a62e94cabb Remove invalid tests.

for which tests already exist.

e3195fa4a5 Cast PTRDIFF_MAX to size_t before adding 1. 
This fixes compilation warnings regarding integer overflow that were
introduced by 0c516a00c4 (Make *allocx()
size class overflow behavior defined.).

0c516a00c4 Make *allocx() size class overflow behavior defined. 
Limit supported size and alignment to HUGE_MAXCLASS, which in turn is
now limited to be less than PTRDIFF_MAX.

This resolves #278 and #295.

2b1fc90b7b Remove rbt_nil 
Since this is an intrusive tree, rbt_nil is the whole size of the node
and can be quite large.  For example, miscelm is ~100 bytes.

0da8ce1e96 Use table lookup for run_quantize_{floor,ceil}(). 
Reduce run quantization overhead by generating lookup tables during
bootstrapping, and using the tables for all subsequent run quantization.

a9a4684792 Test run quantization. 
Also rename run_quantize_*() to improve clarity.  These tests
demonstrate that run_quantize_ceil() is flawed.

9bad079039 Refactor time_* into nstime_*. 
Use a single uint64_t in nstime_t to store nanoseconds rather than using
struct timespec.  This reduces fragility around conversions between long
and uint64_t, especially missing casts that only cause problems on
32-bit platforms.

243f7a0508 Implement decay-based unused dirty page purging. 
This is an alternative to the existing ratio-based unused dirty page
purging, and is intended to eventually become the sole purging
mechanism.

Add mallctls:
- opt.purge
- opt.decay_time
- arena.<i>.decay
- arena.<i>.decay_time
- arenas.decay_time
- stats.arenas.<i>.decay_time

This resolves #325.

8e82af1166 Implement smoothstep table generation. 
Check in a generated smootherstep table as smoothstep.h rather than
generating it at configure time, since not all systems (e.g. Windows)
have dc.

fed1f9f367 Fix intermittent xallocx() test failures. 
Modify xallocx() tests that expect to expand in place to use a separate
arena.  This avoids the potential for interposed internal allocations
from e.g. heap profile sampling to disrupt the tests.

This resolves #286.

044047fae1 Remove fragile xallocx() test case. 
In addition to depending on map coalescing, the test depended on
munmap() being disabled so that chunk recycling would always succeed.

03eb37e8fd Make mallocx() OOM test more robust.

allocate the majority of virtual address space in a single contiguous
region.

d260f442ce Fix xallocx(..., MALLOCX_ZERO) bugs. 
Zero all trailing bytes of large allocations when
--enable-cache-oblivious configure option is enabled.  This regression
was introduced by 8a03cf039c (Implement
cache index randomization for large allocations.).

Zero trailing bytes of huge allocations when resizing from/to a size
class that is not a multiple of the chunk size.

676df88e48 Rename arena_maxclass to large_maxclass. 
arena_maxclass is no longer an appropriate name, because arenas also
manage huge allocations.

a00b10735a Fix "prof.reset" mallctl-related corruption. 
Fix heap profiling to distinguish among otherwise identical sample sites
with interposed resets (triggered via the "prof.reset" mallctl).  This
bug could cause data structure corruption that would most likely result
in a segfault.

4a2a3c9a6e Don't purge junk filled chunks when shrinking huge allocations 
When junk filling is enabled, shrinking an allocation fills the bytes
that were previously allocated but now aren't. Purging the chunk before
doing that is just a waste of time.

This resolves #260.

arenas_cache is torn down.
