Summary: The type in the NEW_C_HEAP_ARRRY and FREE_C_HEAP_ARRAY calls in the buffer \
allocation code was changed from void* to char as the size argument had already been \

6902303: G1: ScavengeALot should cause an incremental, rather than a full, collection
Summary: ScavengeALot now causes an incremental (but possibly partially young, in the \
G1 sense) collection. Some such collections may be abandoned on account of MMU specs. \
Band-aided a native leak associated with abandoned pauses, as well as an MMU tracker \
overflow related to frequent scavenge events in the face of a large MMU denominator \
                interval; the latter is protected by a product flag that defaults to \
                false.

6899058: G1: Internal error in ptrQueue.cpp:201 in nightly tests
Summary: Fixes a race on the dirty card queue completed buffer list between worker \
thread(s) performing a flush of a deferred store barrier (enqueueing a newly \
completed buffer) and worker thread(s) in the RSet updating code claiming completed \
buffers. Removed the routine that removes elements from the completed update buffer \
                queue using a CAS.

6906727: UseCompressedOops: some card-marking fixes related to object arrays
Summary: Introduced a new write_ref_array(HeapWords* start, size_t count) method that \
does the requisite MemRegion range calculation so (some of the) clients of the \
erstwhile write_ref_array(MemRegion mr) do not need to worry. This removed all \
external uses of array_size(), which was also simplified and made private. Asserts \
were added to catch other possible issues. Further, less essential, fixes stemming \
                from this investigation are deferred to CR 6904516 (to follow shortly \
                in hs17).
