Summary:
Extend the plugin architecture to allow for the inclusion, building and testing of Java and JNI components of a plugin. This will cause the JAR built by `$ make rocksdbjava` to include the extra functionality provided by the plugin, and will cause `$ make jtest` to add the java tests provided by the plugin to the tests built and run by Java testing.
The plugin's `<plugin>.mk` file can define:
```
<plugin>_JNI_NATIVE_SOURCES
<plugin>_NATIVE_JAVA_CLASSES
<plugin>_JAVA_TESTS
```
The plugin should provide java/src, java/test and java/rocksjni directories. When a plugin is required to be build it must be named in the ROCKSDB_PLUGINS environment variable (as per the plugin architecture). This now has the effect of adding the files specified by the above definitions to the appropriate parts of the build.
An example of a plugin with a Java component can be found as part of the hdfs plugin in https://github.com/riversand963/rocksdb-hdfs-env - at the time of writing the Java part of this fails tests, and needs a little work to complete, but it builds correctly under the plugin model.

For RocksDB v7 major release. Remove previously deprecated Java API methods and associated tests
- where equivalent/alternative functionality exists and is already tested AND
- where the core RocksDB function/feature has also been removed
- OR the functionality exists only in Java so the previous deprecation only affected Java methods
RETAIN deprecated Java which reflects functionality which is deprecated by, but also still supported by, the core of RocksDB.

Summary:
For RocksJava 7 we will move from requiring Java 7 to Java 8.
* This simplifies the `Makefile` as we no longer need to deal with Java 7; so we no longer use `javah`.
* Added a java-version target which is invoked by the java target, and which exits if the version of java being used is not 8 or greater.
* Enforces java 8 as a minimum.
* Fixed CMake build.
* Fixed broken java event listener test, as the test was broken and the assertions in the callbacks were not causing assertions in the tests. The callbacks now queue up assertion errors for the main thread of the tests to check.
* Fixed C++ dangling pointers in the test code.

Summary:
Transaction multiGet convert to list-based.
RocksDB Java (non-transactional) has multiGetAsList() methods to expose multiGet(). These return a list of results. These methods replaced multiGet() methods returning an array of results, which were deprecated in Rocks 6 and are being removed in Rocks 7.
The transactional API still presents multiGet() methods returning arrays, so in Rocks 7 we replace these with multiGetAsList()methods and deprecate the multiGet() methods.
This does not require any changes to the supporting JNI/C++ code, only to the wrappers which present the Java API.

Summary:
For RocksDB 7. Remove deprecated dispose() And as a consequence remove finalize(), which is good Modern Java hygiene.
It is extremely non-deterministic when `finalize()` is called on an object, and resource closure/recovery of underlying native/C++ objects and/or non-memory resource cannot be adequately controlled through GC finalization. The RocksDB Java/JNI interface provides and encourages the use of AutoCloseable objects with close() methods, allowing predictable disposal of resources at exit from try-with-resource blocks.

Summary:
The LastSequence field in the MANIFEST file is the baseline seqno for a recovered DB. Recovering WAL entries might cause the recovered DB's seqno to advance above this baseline, but the recovered DB will never use a smaller seqno.
Before this PR, we were writing the DB's seqno at the time of LogAndApply() as the LastSequence value. This works in the sense that it is a large enough baseline for the recovered DB that it'll never overwrite any records in existing SST files. At the same time, it's arbitrarily larger than what's needed. This behavior comes from LevelDB, where there was no tracking of largest seqno in an SST file.
Now we know the largest seqno of newly written SST files, so we can write an exact value in LastSequence that actually reflects the largest seqno in any file referred to by the MANIFEST. This is primarily useful for correctness testing with unsynced data loss, where the recovered DB's seqno needs to indicate what records were recovered.

- https://github.com/facebook/rocksdb/issues/9338 adds crash-recovery correctness testing coverage for WAL disabled use cases
- https://github.com/facebook/rocksdb/issues/9357 will extend that testing to cover file ingestion
- Added assertion at end of LogAndApply() for `VersionSet::descriptor_last_sequence_` consistency with files
- Manually tested upgrade/downgrade compatibility with a custom crash test that randomly picks between a `db_stress` built with and without this PR (for old code it must run with `-disable_wal=0`)

Summary:
Existing multiGet() in java calls multi_get_helper() which then calls DB::std::vector MultiGet(). This doesn't take advantage of io_uring.
This change adds another JNI level method that runs a parallel code path using the DB::void MultiGet(), using ByteBuffers at the JNI level. We call it multiGetDirect(). In addition to using the io_uring path, this code internally returns pinned slices which we can copy out of into our direct byte buffers; this should reduce the overall number of copies in the code path to/from Java. Some jmh benchmark runs (100k keys, 1000 key multiGet) suggest that for value sizes > 1k, we see about a 20% performance improvement, although performance is slightly reduced for small value sizes, there's a little bit more overhead in the JNI methods.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9266
This diff adds a new tag `CommitWithTimestamp`. Currently, there is no API to trigger writing
this tag to WAL, thus it is unavailable to users.
This is an ongoing effort to add user-defined timestamp support to write-committed transactions.
This diff also indicates all column families that may potentially participate in the same
transaction must either disable timestamp or have the same timestamp format, since
`CommitWithTimestamp` tag is followed by a single byte-array denoting the commit
timestamp of the transaction. We will enforce this checking in a future diff. We keep this
diff small.

Summary:
**Context:**
Searching `TableProperties::properties_offsets` across the codebase reveals that internally it is only used to find the external SST file's global seqno offeset. Therefore we can narrow it down and replace this map property with a uint64_t property `external_sst_file_global_seqno_offset` to save memory usage related to table properties.
Note:
- See PR comments for discussion about potential impact on existing external usage of `TableProperties::properties_offsets`
- See PR comments for discussion on keeping external SST file global seqno's offset VS using a simple flag indicating seqno's existence.
**Summary:**
- Replaced `TableProperties::properties_offsets` with `TableProperties::external_sst_file_global_seqno_offset`
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9212
Test Plan: - Relied on existing tests should be sufficient since `TableProperties::properties_offsets` existed before and should already be tested.

Implementation of https://github.com/facebook/rocksdb/issues/8221, plus/including extension of Java options API to allow the get() of options from RocksDB. The extension allows more comprehensive testing of options at the Java side, by validating that the options are set at the C++ side.
Variations on methods:
MutableColumnFamilyOptions.MutableColumnFamilyOptionsBuilder getOptions()
MutableDBOptions.MutableDBOptionsBuilder getDBOptions()
retrieve the options via RocksDB C++ interfaces, and parse the resulting string into one of the Java-style option objects.
This necessitated generalising the parsing of option strings in Java, which now parses the full range of option strings returned by the C++ interface, rather than a useful subset. This necessitates the list-separator being changed to :(colon) from , (comma).
