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.
