Summary: We now reads table properties in VersionSet::LogAndApply(), which requires options.db_paths to be set. But since ldb_cmd directly creates VersionSet without initialization db_paths, causing a seg fault. This patch fix it by initializing db_paths. log_and_apply_bench still shows segfault, because table cache is nullptr in VersionSet created. Test Plan: Run ldb dump_manifest which used to fail.

Summary: In block based table's hash index checking, when looking for a key that doesn't exist, there is a high chance that a false block is returned because of hash bucket conflicts. In this revision, another check is done to filter out some of those cases: comparing previous key of the block boundary to see whether the target block is what we are looking for. In a favored test setting (bloom filter disabled, 8 L0 files), I saw about 80% improvements. In a non-favored test setting (bloom filter enabled, files are all in L1, files are all cached), I see the performance penalty is less than 3%.

Summary: This diff is adding spatial index support to RocksDB. When creating the DB user specifies a list of spatial indexes. Spatial indexes can cover different areas and have different resolution (i.e. number of tiles). This is useful for supporting different zoom levels. Each element inserted into SpatialDB has: * a bounding box, which determines how will the element be indexed * string blob, which will usually be WKB representation of the polygon (http://en.wikipedia.org/wiki/Well-known_text) * feature set, which is a map of key-value pairs, where value can be int, double, bool, null or a string. FeatureSet will be a set of tags associated with geo elements (for example, 'road': 'highway' and similar) * a list of indexes to insert the element in. For example, small river element will be inserted in index for high zoom level, while country border will be inserted in all indexes (including the index for low zoom level). Each query is executed on single spatial index. Query guarantees that it will return all elements intersecting the specified bounding box, but it might also return some extra non-intersecting elements.

Summary: All public headers need to be under `include/rocksdb` directory. Otherwise, clients include our header files like this: #include <rocksdb/db.h> #include <utilities/backupable_db.h> // still our public header! Also, internally, we include: #include "utilities/backupable/backupable_db.h" // internal header #include "utilities/backupable_db.h" // public header which is confusing. This way, when we install rocksdb as a system library, we can just copy `include/rocksdb` directory to system's header files. We can't really copy `utilities` directory to system's header files.

Summary: Add a function GetOptions(), where based on four parameters users give: read/write amplification threshold, memory budget for mem tables and target DB size, it picks up a compaction style and parameters for them. Background threads are not touched yet. One limit of this algorithm: since compression rate and key/value size are hard to predict, it's hard to predict level 0 file size from write buffer size. Simply make 1:1 ratio here.
