FileDataStore: only open a stream when really necessary

                 Key: JCR-2067
                 URL: https://issues.apache.org/jira/browse/JCR-2067
             Project: Jackrabbit Content Repository
          Issue Type: Improvement
            Reporter: Thomas Mueller
            Assignee: Thomas Mueller

Currently, PropertyImpl.getValue() opens a FileInputStream if the FileDataStore is used.
If the application doesn't use the value, this stream is never closed.

  return internalGetValue().toJCRValue(session);
  case PropertyType.BINARY:
    return new BinaryValue(((BLOBFileValue) val).getStream());
  return getDataRecord().getStream();
  return new FileInputStream(file);

One solution is to return a 'lazy' file input stream that only opens the file when reading
from the stream (and closing the file when the last byte was read). Maybe there is already
a class (in Apache Commons maybe?) that can do that.
