8da69b69e6 Fix support for GNU/kFreeBSD
The configure.ac seciton right now is the same for Linux and kFreeBSD,
which results into an incorrect configuration of e.g. defining
JEMALLOC_PROC_SYS_VM_OVERCOMMIT_MEMORY instead of FreeBSD's
JEMALLOC_SYSCTL_VM_OVERCOMMIT.

GNU/kFreeBSD is really a glibc + FreeBSD kernel system, so it needs its
own entry which has a mixture of configuration options from Linux and
FreeBSD.

3ec279ba1c Fix test/unit/pages.
As part of the metadata_thp support, We now have a separate swtich
(JEMALLOC_HAVE_MADVISE_HUGE) for MADV_HUGEPAGE availability.  Use that instead
of JEMALLOC_THP (which doesn't guard pages_huge anymore) in tests.

8fdd9a5797 Implement opt.metadata_thp
This option enables transparent huge page for base allocators (require
MADV_HUGEPAGE support).

048c6679cd Remove external linkage for spin_adaptive
The external linkage for spin_adaptive was not used, and the inline
declaration of spin_adaptive that was used caused a probem on FreeBSD
where CPU_SPINWAIT is implemented as a call to a static procedure for
x86 architectures.

1ab2ab294c Only read szind if ptr is not paged aligned in sdallocx.
If ptr is not page aligned, we know the allocation was not sampled. In this case
use the size passed into sdallocx directly w/o accessing rtree.  This improve
sdallocx efficiency in the common case (not sampled && small allocation).

3800e55a2c Bypass extent_alloc_wrapper_hard for no_move_expand.
When retain is enabled, we should not attempt mmap for in-place expansion
(large_ralloc_no_move), because it's virtually impossible to succeed, and causes
unnecessary syscalls (which can cause lock contention under load).

7c22ea7a93 Only run test/integration/sdallocx non-reentrantly.
This is a temporary workaround until we add some beefier CI machines.  Right
now, we're seeing too many OOMs for this to be useful.

e6aeceb606 Logging: log using the log var names directly.
Currently we have to log by writing something like:

  static log_var_t log_a_b_c = LOG_VAR_INIT("a.b.c");
  log (log_a_b_c, "msg");

This is sort of annoying.  Let's just write:

  log("a.b.c", "msg");

b28f31e7ed Split out cold code path in newImpl
I noticed that the whole newImpl is inlined. Since OOM handling code is
rarely executed, we should only inline the hot path.

a9f7732d45 Logging: allow logging with empty varargs.
Currently, the log macro requires at least one argument after the format string,
because of the way the preprocessor handles varargs macros.  We can hide some of
that irritation by pushing the extra arguments into a varargs function.

9761b449c8 Add a logging facility.
This sets up a hierarchical logging facility, so that we can add logging
statements liberally, and turn them on in a fine-grained manner.

0975b88dfd Fall back to FD_CLOEXEC when O_CLOEXEC is unavailable.
Older Linux systems don't have O_CLOEXEC.  If that's the case, we fcntl
immediately after open, to minimize the length of the racy period in
which an
operation in another thread can leak a file descriptor to a child.

fb6787a78c Add a test of behavior under multi-threaded forking.
Forking a multithreaded process is dangerous but allowed, so long as the child
only executes async-signal-safe functions (e.g. exec).  Add a test to ensure
that we don't break this behavior.

0a4f5a7eea Fix deadlock in multithreaded fork in OS X.
On OS X, we rely on the zone machinery to call our prefork and postfork
handlers.

In zone_force_unlock, we call jemalloc_postfork_child, reinitializing all our
mutexes regardless of state, since the mutex implementation will assert if the
tid of the unlocker is different from that of the locker.  This has the effect
of unlocking the mutexes, but also fails to wake any threads waiting on them in
the parent.

To fix this, we track whether or not we're the parent or child after the fork,
and unlock or reinit as appropriate.

This resolves #895.

52fc887b49 Avoid inactivity_check within background threads.
Passing is_background_thread down the decay path, so that background thread
itself won't attempt inactivity_check.  This fixes an issue with background
thread doing trylock on a mutex it already owns.

9b1befabbb Add minimal initialized TSD.
We use the minimal_initilized tsd (which requires no cleanup) for free()
specifically, if tsd hasn't been initialized yet.

Any other activity will transit the state from minimal to normal.  This is to
workaround the case where a thread has no malloc calls in its lifetime until
during thread termination, free() happens after tls destructors.
