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.

overhead.
