[drlvm][memory] Native memory management and tuning
---------------------------------------------------

                 Key: HARMONY-5684
                 URL: https://issues.apache.org/jira/browse/HARMONY-5684
             Project: Harmony
          Issue Type: Improvement
          Components: DRLVM
            Reporter: Andrey Yakushev


There are several problems in DRLVM with native memory usage. For example:
- Native memory usage couldn't be monitored currently in details via java.lang.management
functionality
- No explicit way to replace system native memory allocator to other memory managers in order
to improve performance or footprint
- Too many variants of the native memory allocations in DRLVM
- Poor memory usage control (like leaks, double free calling, etc.)
- Potential crash in diagnostics when OutOfMemory occur
- Frequent native memory usage could cause OutOfMemory if GC wouldn't be timely called
- No detail trace for the native memory usage

Adding of some functionality to solve these would be hepful I think?
