6a79248b42 dm vdo permassert: audit all of ASSERT to test for VDO_SUCCESS
Also rename ASSERT to VDO_ASSERT and ASSERT_LOG_ONLY to
VDO_ASSERT_LOG_ONLY.

But re-introduce ASSERT and ASSERT_LOG_ONLY as a placeholder
for the benefit of dm-vdo/indexer.

cc46b9554b dm vdo: add basic hash map data structures
This patch adds two hash maps, one keyed by integers, the other by
pointers, and also a priority heap. The integer map is used for locking of
logical and physical addresses. The pointer map is used for managing
concurrent writes of the same data, ensuring that those writes are
deduplicated. The priority heap is used to minimize the search time for
free blocks.
