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().

Create a custom assert() implementation in order to avoid recursive
deadlock. Enable assertions on Windows (for debug builds).

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.

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.

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.

Bug 431735: Use rb.h instead of tree.h, r=benjamin
...
Use rb.h instead of tree.h for red-black trees, in order to reduce memory
overhead.

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.
