Summary: The patch adds iterator support to the integrated BlobDB implementation. Whenever a blob reference is encountered during iteration, the corresponding blob is retrieved by calling `Version::GetBlob`, assuming the `expose_blob_index` (formerly `allow_blob`) flag is *not* set. (Note: the flag is set by the old stacked BlobDB implementation, which has its own blob file handling/blob retrieval logic.) In addition, `DBIter` now uniformly returns `Status::NotSupported` with the error message `"BlobDB does not support merge operator."` when encountering a blob reference while performing a merge (instead of potentially returning a message that implies the database should be opened using the stacked BlobDB's `Open`.) TODO: We can implement support for lazily retrieving the blob value (or in other words, bypassing the retrieval of blob values based on key) by extending the `Iterator` API with a new `PrepareValue` method (similarly to `InternalIterator`, which already supports lazy values).
