This commit adds two additional helpers to opal/class:
- OPAL_HASH_TABLE_FOREACH_PTR: Same as OPAL_HASH_TABLE_FOREACH but
operating on ptr hash tables. This is needed because the _ptr
iterator functions take an additional argument.
- OPAL_LIST_FOREACH_DECL: Same as OPAL_LIST_FOREACH but declares
the variable specified in the first argument.
