Discussion about unifying the wording buffer/node/element in G1, especially classes using G1SegmentedArray and related classes

[Albert Yang]

> The relationship is: Segmented array (1) <---> (N) buffer (1) <---> (M) element. So element is an item, e.g. an offset, a pointer, ...

Picking one suggestion from your first email:

G1CardSetAllocator::_num_free_nodes

node -> elem

`_num_free_slot` is, IMO, more accurate. An element is sth the user of the segmented array who provides.

> can I assume you mean: Segmented array (1) <---> (N) slot (1) <---> (M) element ?

One segmented array contains N subarray, each subarray contains M slots (M can be different for different subarrays), each slot contains a single element (provided by users of this data structure) or empty (initial state).

segmented array (1) -- subarray (N) -- slot (M) -- element (1)
