Summary:
Add the following missing options to `src/main/java/org/rocksdb/CompactRangeOptions.java` and in `java/rocksjni/options.cc` in RocksJava.
For the descriptions and API see the C++ file `include/rocksdb/options.h`, specifically the struct `CompactRangeOptions`
* full_history_ts_low
* canceled
We changed the handle to return an object (of class `Java_org_rocksdb_CompactRangeOptions`) containing a `ROCKSDB_NAMESPACE::CompactRangeOptions` at (almost certainly) 0-offset, rather than a raw `ROCKSDB_NAMESPACE::CompactRangeOptions`.
The `Java_org_rocksdb_CompactRangeOptions` contains as supplementary fields objects (std::string, std::atomic<bool>) which are passed as pointers to the `ROCKSDB_NAMESPACE::CompactRangeOptions` and which must therefore live for as long as the `ROCKSDB_NAMESPACE::CompactRangeOptions`. By placing them in a `Java_org_rocksdb_CompactRangeOptions` we achieve this.
Because the field offset of the `ROCKSDB_NAMESPACE::CompactRangeOptions` member is (very probably) 0, casting the handle to ROCKSDB_NAMESPACE::CompactRangeOptions works (i.e. old methods didn’t have to be changed), but really that’s a minefield and the correct answer is to cast to the correct type (Java_org_rocksdb_CompactRangeOptions) and then use the ROCKSDB_NAMESPACE::CompactRangeOptions field in that. So the get/set methods for existing parameters have this change.
Testing
-------
We added unit tests for getting and setting the newly implemented fields to `CompactRangeOptionsTest`

Summary:
When dynamically linking two binaries together, different builds of RocksDB from two sources might cause errors. To provide a tool for user to solve the problem, the RocksDB namespace is changed to a flag which can be overridden in build time.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6433
Test Plan: Build release, all and jtest. Try to build with ROCKSDB_NAMESPACE with another flag.

Summary:
Closes https://github.com/facebook/rocksdb/issues/4195
CompactRangeOptions are available the CPP API, but not in the Java API. This PR adds CompactRangeOptions to the Java API and adds an overloaded compactRange() method. See https://github.com/facebook/rocksdb/issues/4195 for the original discussion.
This change supports all fields of CompactRangeOptions, including the required enum converters in the JNI portal.
Significant changes:
- Make CompactRangeOptions available in the compactRange() for Java.
- Deprecate other compactRange() methods that have individual option params, like in the CPP code.
- Migrate rocksdb_compactrange_helper() to CompactRangeOptions.
- Add Java unit tests for CompactRangeOptions.
