6dc51eca81 - Fix setting of MK_GSSAPI option by bsd.own.mk; its value should
default to the value of MK_KERBEROS unless set explicitly by
  WITH_GSSAPI/WITHOUT_GSSAPI.  (This introduces another type of
  MK_* variables which itself is questionable.)

a59d6a8724 Implementing 'fallback' nsswitch source. 'fallback' source is used
when particular function can't be found in nsswitch-module. For
example, getgrouplist(3) will use module-supplied 'getgroupmembership'
function (which can work in an optimal way for such source as LDAP) and
will fall back to the stanard iterate-through-all-groups implementation
otherwise.

3fe21f77bc Hide the building and installation of libgssapi behind the
WITHOUT_KERBEROS knob. While GSS can be used for other things
some third party software (most notably ports/x11/kdelibs3)
takes the presence of libgssapi as an indication that kerberos
is available, and attempts to link with the kerberos libs. If
they are not available, the build will fail.

Because you might want to use GSS but not kerberos, add a knob
to re-enable it if WITHOUT_KERBEROS is present.

Document the new knob, and the new behavior of WITHOUT_KERBEROS.

396a73603d Set the tcb (thread control block) in the child process after a fork.
This protects against a race with an upcall in the parent during the
fork which can clobber the parent's tcb before the vm space is copied
in the child.  The child then gets a corrupted tcb that is either null
or that points to another thread that doesn't exist in the child (after
a fork, only the fork()ing thread exists in the child).

5ea8413d0a Implement dynamic load balancing of thread-->arena mapping, based on lock
contention.  The intent is to dynamically adjust to load imbalances, which
can cause severe contention.

Use pthread mutexes where possible instead of libc "spinlocks" (they aren't
actually spin locks).  Conceptually, this change is meant only to support
the dynamic load balancing code by enabling the use of spin locks, but it
has the added apparent benefit of substantially improving performance due to
reduced context switches when there is moderate arena lock contention.

Proper tuning parameter configuration for this change is a finicky business,
and it is very much machine-dependent.  One seemingly promising solution
would be to run a tuning program during operating system installation that
computes appropriate settings for load balancing.  (The pthreads adaptive
spin locks should probably be similarly tuned.)

26b5e3a18e Implement lazy deallocation of small objects. For each arena, maintain a
vector of slots for lazily freed objects.  For each deallocation, before
doing the hard work of locking the arena and deallocating, try several times
to randomly insert the object into the vector using atomic operations.

This approach is particularly effective at reducing contention for
multi-threaded applications that use the producer-consumer model, wherein
one producer thread allocates objects, then multiple consumer threads
deallocate those objects.
