2a80d6f15b Avoid a printf format specifier warning. 
This dodges a warning emitted by the FreeBSD system gcc when compiling
libc for architectures which don't use clang as the system compiler.

3f0dc64c6b Allow setting extent hooks on uninitialized auto arenas. 
Setting extent hooks can result in initializing an unused auto arena.  This is
useful to install extent hooks on auto arenas from the beginning.

8b14f3abc0 background_thread: add max thread count config 
Looking at the thread counts in our services, jemalloc's background thread
is useful, but mostly idle.  Add a config option to tune down the number of threads.

4be74d5112 Consolidate the two memory loads in rtree_szind_slab_read(). 
szind and slab bits are read on fast path, where compiler generated two memory
loads separately for them before this diff.  Manually operate on the bits to
avoid the extra memory load.

6d02421730 extents: Remove preserve_lru feature. 
preserve_lru feature adds lots of complication, for little value.
Removing it means merged extents are re-added to the lru list, and may
take longer to madvise away than they otherwise would.

Canaries after removal seem flat for several services (no change).

21eb0d15a6 Fix a background_thread shutdown issue. 
1) make sure background thread 0 is always created; and 2) fix synchronization
between thread 0 and the control thread.

4c36cd2cc5 Stats printing: Convert arena large stats to use emitter. 
This completes the conversion; we now have only structured text output.

a9f3cedc6e Stats printing: remove a spurious newline. 
This was left over from a previous emitter conversion.  It didn't affect the
correctness of the output.

ebe0b5f828 Emitter: Add support for row-based output in table mode.

9e1846b004 Stats printing: move non-mutex arena stats to the emitter. 
Another step in the conversion process.  The mutex is a little different,
because we we want to emit it as an array.

8076b28721 Stats printing: Remove explicit callback passing to stats_print_helper. 
This makes the emitter the only source of callback information, which is a step
towards where we want to be.

0d20eda127 Stats printing: Move emitter -> manual cutoff point. 
This makes it so that the "general" portion of the stats code is completely
agnostic to emitter type.

27a8fe6780 Introduce the emitter module. 
The emitter can be used to produce structured json or tabular output.  For now
it has no uses; in subsequent commits, I'll begin transitioning stats printing
code over.

e4f090e8df Add opt.thp which allows explicit hugepage usage. 
"always" marks all user mappings as MADV_HUGEPAGE; while "never" marks all
mappings as MADV_NOHUGEPAGE. The default setting "default" does not change any
settings.  Note that all the madvise calls are part of the default extent hooks
by design, so that customized extent hooks have complete control over the
mappings including hugepage settings.

6b35366ef5 Skip test_alignment_and_size if percpu_arena is enabled. 
test_alignment_and_size needs a lot of memory.  When percpu_arena is enabled,
multiple arenas may cause the test to OOM.

26b1c13982 Background threads: fix an indexing bug. 
We have a buffer overrun that manifests in the case where arena indices higher
than the number of CPUs are accessed before arena indices lower than the number
of CPUs.  This fixes the bug and adds a test.

dd7e283b6f Tweak the ticker paths to help GCC generate better code. 
GCC on its own isn't quite able to turn the ticker subtract into a memory
operation followed by a js.

f78d4ca3fb Modify configure to determine return value of strerror_r. 
On glibc and Android's bionic, strerror_r returns char* when
_GNU_SOURCE is defined.

Add a configure check for this rather than assume glibc is the
only libc that behaves this way.

ba5992fe9a Improve the fit for aligned allocation. 
We compute the max size required to satisfy an alignment.  However this can be
quite pessimistic, especially with frequent reuse (and combined with state-based
fragmentation).  This commit adds one more fit step specific to aligned
allocations, searching in all potential fit size classes.
