Add the --disable-initial-exec-tls configure option.
...
Right now we always make our TLS use the initial-exec model if the compiler
supports it. This change allows configure-time disabling of this setting, which
can be helpful when dynamically loading jemalloc is the only option.

processing loop.

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

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.

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.

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.

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).

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.

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.
