Summary: This change enables custom implementations of FilterPolicy to wrap a variety of NewBloomFilterPolicy and select among them based on contextual information such as table level and compaction style. * Moves FilterBuildingContext to public API and elaborates it with more useful data. (It would be nice to put more general options-like data, but at the time this object is constructed, we are using internal APIs ImmutableCFOptions and MutableCFOptions and don't have easy access to ColumnFamilyOptions that I can tell.) * Renames BloomFilterPolicy::GetFilterBitsBuilderInternal to GetBuilderWithContext, because it's now public. * Plumbs through the table's "level_at_creation" for filter building context. * Simplified some tests by adding GetBuilder() to MockBlockBasedTableTester. * Adds test as DBBloomFilterTest.ContextCustomFilterPolicy, including sample wrapper class LevelAndStyleCustomFilterPolicy. * Fixes a cross-test bug in DBBloomFilterTest.OptimizeFiltersForHits where it does not reset perf context.
