Add stats unit tests.

#include "test/jemalloc_test.h"
Stats: Fix tcache_bytes reporting. Previously, large allocations in tcaches would have their sizes reduced during stats estimation. Added a test, which fails before this change but passes now. This fixes a bug introduced in 593484661261c20f75557279931eb2d9ca165185, which was itself fixing a bug introduced in 9c0549007dcb64f4ff35d37390a9a6a8d3cea880.

Refactor huge allocation to be managed by arenas. Refactor huge allocation to be managed by arenas (though the global red-black tree of huge allocations remains for lookup during deallocation). This is the logical conclusion of recent changes that 1) made per arena dss precedence apply to huge allocation, and 2) made it possible to replace the per arena chunk allocation/deallocation functions. Remove the top level huge stats, and replace them with per arena huge stats. Normalize function names and types to *dalloc* (some were *dealloc*). Remove the --enable-mremap option. As jemalloc currently operates, this is a performace regression for some applications, but planned work to logarithmically space huge size classes should provide similar amortized performance. The motivation for this change was that mremap-based huge reallocation forced leaky abstractions that prevented refactoring.

Implement two-phase decay-based purging. 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.

Hide size class computation behind a layer of indirection. This class removes almost all the dependencies on size_classes.h, accessing the data there only via the new module sc.h, which does not depend on any configuration options. In a subsequent commit, we'll remove the configure-time size class computations, doing them at boot time, instead.

SC: Make some key size classes static. The largest small class, smallest large class, and largest large class may all be needed down fast paths; to avoid the risk of touching another cache line, we can make them available as constants.

Remove --disable-tcache. Simplify configuration by removing the --disable-tcache option, but replace the testing for that configuration with --with-malloc-conf=tcache:false. Fix the thread.arena and thread.tcache.flush mallctls to work correctly if tcache is disabled. This partially resolves #580.

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.

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.

Add basic reentrancy-checking support, and allow arena_new to reenter. This checks whether or not we're reentrant using thread-local data, and, if we are, moves certain internal allocations to use arena 0 (which should be properly initialized after bootstrapping). The immediate thing this allows is spinning up threads in arena_new, which will enable spinning up background threads there.
