- Update to version 4.1.0

New features:
  * Implement decay-based unused dirty page purging, a major optimization
    with mallctl API impact. This is an alternative to the existing ratio-based
    unused dirty page purging, and is intended to eventually become the sole 
    purging mechanism. New mallctls:
    + opt.purge
    + opt.decay_time
    + arena.<i>.decay
    + arena.<i>.decay_time
    + arenas.decay_time
    + stats.arenas.<i>.decay_time
  * Add --with-malloc-conf, which makes it possible to embed a default options
    string during configuration. This was motivated by the desire to specify 
    --with-malloc-conf=purge:decay , since the default must remain purge:ratio
    until the 5.0.0 release.
  * Make *allocx() size class overflow behavior defined. The maximum size
    class is now less thanPTRDIFF_MAX to protect applications against numerical
    overflow, and all allocation functions are guaranteed to indicate errors 
    rather than potentially crashing if the request size exceeds the maximum size class.
  * jeprof:
    + Add raw heap profile support.
    + Add --retain and --exclude for backtrace symbol filtering.
  Optimizations:
  * Optimize the fast path to combine various bootstrapping and configuration
    checks and execute more streamlined code in the common case.
  * Use linear scan for small bitmaps (used for small object tracking). 
   In addition to speeding up bitmap operations on 64-bit systems, this reduces
   allocator metadata overhead by approximately 0.2%.
  * Separate arena_avail trees, which substantially speeds up run tree operations.

+  * Attempt mmap-based in-place huge reallocation. This can dramatically speed up
+    incremental huge reallocation.
+
+  Incompatible changes:
+  * Make opt.narenas unsigned rather than size_t.
+
+  Bug fixes:
+  * Fix stats.cactive accounting regression.
+  * Handle unaligned keys in hash(). This caused problems for some ARM systems.
+  * Refactor arenas array. In addition to fixing a fork-related deadlock, 
+    this makes arena lookups faster and simpler.
+  * Move retained memory allocation out of the default chunk allocation function,
+    to a location that gets executed even if the application installs a custom chunk
+    allocation function. This resolves a virtual memory leak.  
+  * Fix a potential tsd cleanup leak.
+  * Fix run quantization. In practice this bug had no impact unless applications
+    requested memory with alignment exceeding one page. 
+  * Fix LinuxThreads-specific bootstrapping deadlock. (Cosmin Paraschiv) 
+  * jeprof:
+    + Don't discard curl options if timeout is not defined. (@djwatson)
+    + Detect failed profile fetches. (@djwatson)
+ * Fix stats.arenas.<i>.{dss,lg_dirty_mult,decay_time,pactive,pdirty} for --disable-stats case.
