f40f49c8a5 Bug 478576 - infinite loop in jemalloc:chunk_recycle_reserve; r=pavlov 
Avoid an infinite loop if the malloc reserve is depleted and there are no
registered event notification handlers.

9ee1b50d11 Bug 446096: Integrate upstream jemalloc optimizations, r=pavlov 
Enhance arena_chunk_map_t to directly support run coalescing, and use
the chunk map instead of red-black trees where possible.  Remove the
red-black trees and node objects that are obsoleted by this change.  The
net result is a ~1-2% memory savings, and a substantial allocation speed
improvement.

Add a radix tree to optimize isalloc_validate().

0481b0a0ab Bug 446090: Fix assertions in jemalloc, r=pavlov 
Create a custom assert() implementation in order to avoid recursive
deadlock.  Enable assertions on Windows (for debug builds).

d6f55ddb16 Bug 427109: Add memory reserve and xmalloc() API, r=benjamin 
Add support for a memory reserve, which is managed via the reserve_*() API.

Add xmalloc() variants of malloc()-like functions.  These functions never
return NULL.

d5c3782159 Bug 432475: Remove _malloc_options abuse, r=benjamin 
Don't abuse _malloc_options to set platform-specific options, since doing so
makes the MALLOC_OPTIONS environment variable less useful.

97c3fc2779 Bug 431739: Limit dirty page purging, r=benjamin 
Limit dirty page purging so that it terminates once the number of pages is no
more than half the limit.

Add a separate tree to track arena chunks that contain dirty pages.  This
substantially improves worst case allocation performance, since O(lg n) tree
search can be used instead of O(n) tree iteration.

Use rb.h instead of tree.h for red-black trees, in order to reduce memory
overhead.

380151b1da Bug 431743: Upstream jemalloc fixes, r=benjamin 
Incorporate upstream jemalloc fixes from FreeBSD:
  * Detect overflow for huge allocations via sbrk(2).
  * Fix deadlock for base (internal) allocations in OOM case.
  * Fix bitmap vector initialization for small allocation runs.
