6692906: CMS: parallel concurrent marking may be prone to hanging or stalling \
                mutators for periods of time
Summary: Inserted missing yield(check)s in closures used during the work-stealing \
phase of parallel concurrent marking, a missing synchronous yield-request in the cms \
perm gen allocation path, and a terminator-terminator for the offer_termination \
invocation that monitors the yield status of the concurrent marking task. Elaborated \
some documentation comments and made some task queue termination loop flags \
                configurable at start-up to aid debugging in the field.

6794422: Perm gen expansion policy for concurrent collectors
Summary: Concurrent collectors should expand the perm gen without a full STW GC, but \
possibly by triggering a concurrent collection. Temporary band-aid for G1 where no \

                collected concurrently.

6980838: G1: guarantee(false) failed: thread has an unexpected active value in its \
                SATB queue
Summary: Under certain circumstances a safepoint could happen between a JavaThread \
object being created and that object being added to the Java threads list. This could \
cause the active field of that thread's SATB queue to get out-of-sync with respect to \
the other Java threads. The solution is to activate the SATB queue, when necessary, \
before adding the thread to the Java threads list, not when the JavaThread object is \
created. The changeset also includes a small fix to rename the surrogate locker \
thread from "Surrogate Locker Thread (CMS)" to "Surrogate Locker Thread (Concurrent \
                GC)" since it's also used in G1.
