Header refactoring: Split up jemalloc_internal.h This is a biggy. jemalloc_internal.h has been doing multiple jobs for a while now: - The source of system-wide definitions. - The catch-all include file. - The module header file for jemalloc.c This commit splits up this functionality. The system-wide definitions responsibility has moved to jemalloc_preamble.h. The catch-all include file is now jemalloc_internal_includes.h. The module headers for jemalloc.c are now in jemalloc_internal_[externs|inlines|types].h, just as they are for the other modules.

Refactor jemalloc.c into multiple source files. Fix a stats bug in large object curruns accounting. Replace tcache_bin_fill() with arena_tcache_fill(), and fix a bug in an OOM error path. Fix API name mangling to coexist with __attribute__((malloc)).

Allow je_malloc_message to be overridden when linking statically If an application wants to override je_malloc_message, it is better to define the symbol locally than to change its value in main(), which might be too late for various reasons.

Implement per-CPU arena. The new feature, opt.percpu_arena, determines thread-arena association dynamically based CPU id. Three modes are supported: "percpu", "phycpu" and disabled. "percpu" uses the current core id (with help from sched_getcpu()) directly as the arena index, while "phycpu" will assign threads on the same physical CPU to the same arena. In other words, "percpu" means # of arenas == # of CPUs, while "phycpu" has # of arenas == 1/2 * (# of CPUs). Note that no runtime check on whether hyper threading is enabled is added yet. When enabled, threads will be migrated between arenas when a CPU change is detected. In the current design, to reduce overhead from reading CPU id, each arena tracks the thread accessed most recently. When a new thread comes in, we will read CPU id and update arena if necessary.

Starting from the second hugepage (in a single arena), "auto" behaves the same as "always", i.e. madvise hugepage right away.

The sleep interval of background threads is dynamic and determined by computing number of pages to purge in the future (based on backlog).

Split decay-based purging into two phases, the first of which uses lazy purging to convert dirty pages to "muzzy", and the second of which uses forced purging, decommit, or unmapping to convert pages to clean or destroy them altogether. Not all operating systems support lazy purging, yet the application may provide extent hooks that implement lazy purging, so care must be taken to dynamically omit the first phase when necessary. The mallctl interfaces change as follows: - opt.decay_time --> opt.{dirty,muzzy}_decay_time - arena.<i>.decay_time --> arena.<i>.{dirty,muzzy}_decay_time - arenas.decay_time --> arenas.{dirty,muzzy}_decay_time - stats.arenas.<i>.pdirty --> stats.arenas.<i>.p{dirty,muzzy} - stats.arenas.<i>.{npurge,nmadvise,purged} --> stats.arenas.<i>.{dirty,muzzy}_{npurge,nmadvise,purged} This resolves #521.
