Compaction filter on merge operands Summary: Since Andres' internship is over, I took over https://reviews.facebook.net/D42555 and rebased and simplified it a bit. The behavior in this diff is a bit simpler than in D42555: * only merge operators are passed through FilterMergeValue(). If fitler function returns true, the merge operator is ignored * compaction filter is *not* called on: 1) results of merge operations and 2) base values that are getting merged with merge operands (the second case was also true in previous diff) Do we also need a compaction filter to get called on merge results?

compaction_filter_example
Support for single-primary, multi-secondary instances (#4899) Summary: This PR allows RocksDB to run in single-primary, multi-secondary process mode. The writer is a regular RocksDB (e.g. an `DBImpl`) instance playing the role of a primary. Multiple `DBImplSecondary` processes (secondaries) share the same set of SST files, MANIFEST, WAL files with the primary. Secondaries tail the MANIFEST of the primary and apply updates to their own in-memory state of the file system, e.g. `VersionStorageInfo`. This PR has several components: 1. (Originally in #4745). Add a `PathNotFound` subcode to `IOError` to denote the failure when a secondary tries to open a file which has been deleted by the primary. 2. (Similar to #4602). Add `FragmentBufferedReader` to handle partially-read, trailing record at the end of a log from where future read can continue. 3. (Originally in #4710 and #4820). Add implementation of the secondary, i.e. `DBImplSecondary`. 3.1 Tail the primary's MANIFEST during recovery. 3.2 Tail the primary's MANIFEST during normal processing by calling `ReadAndApply`. 3.3 Tailing WAL will be in a future PR. 4. Add an example in 'examples/multi_processes_example.cc' to demonstrate the usage of secondary RocksDB instance in a multi-process setting. Instructions to run the example can be found at the beginning of the source code.

Fix compact_files_example Summary: See task #7983654. The example was triggering an assert in compaction job because the compaction was not marked as manual. With this patch, CompactionPicker::FormCompaction() marks compactions as manual. This patch also fixes a couple of typos, adds optimistic_transaction_example to .gitignore and librocksdb as a dependency for examples. Adding librocksdb as a dependency makes sure that the examples are built with the latest changes in librocksdb.
