Portlib should be extended to support NIO's mmap funtions
---------------------------------------------------------

                 Key: HARMONY-982
                 URL: http://issues.apache.org/jira/browse/HARMONY-982
             Project: Harmony
          Issue Type: Improvement
          Components: Classlib
            Reporter: Paulex Yang


The port layer currently has the following memory mapping API's

hymmap_map_file()
hymmap_munmap_file()
hymmap_capabilities()

However, these assume that a file exists, that it will be mapped read-only and that the mapping
will only happen to whole file.  All these assumptions are broken by the nio requirements,
so that the current NIO's mmap features are implemented by platform-dependent native codes.
