    DRILL-3492: Add support for encoding/decoding of to/from OrderedBytes

    spanchamiamapr authored jinfengni committed
    format
    
    Description:
    This change allows encoding/decoding of data from/to 'double', 'float',
    'bigint', 'int' and 'utf8' data types to/from OrderedBytes format.
    It also allows for OrderedByte encoded row-keys to be stored in
    ascending as well as descending order.
    
    The following JIRA added the OrderedBytes encoding to HBase:
    https://issues.apache.org/jira/browse/HBASE-8201
    
    This encoding scheme will preserve the sort-order of the native
    data-type when it is stored as sorted byte arrays on disk.
    Thus, it will help the HBase storage plugin if the row-keys have been
    encoded in OrderedBytes format.
    
    This functionality allows us to prune the scan ranges, thus reading much
    lesser data from the server.
    
    Testing Done:
    Added a new unit-test class TestOrderedBytesConvertFunctions.java which
    derives from TestConvertFunctions.java class.
    Also add new test cases to TestHBaseFilterPushDown class that will test
    if we were able to push-down filters correctly and if the results are
    correct.
    
    DRILL-3492 - * Remove repeated allocations of byte arrays and PositionedByteRange objects
    on heap(as suggested by Jason).
    * Remove OrderedBytes encode/decode operations on UTF8 types.
    Reasons -
    1. These operations are slow and incur a lot of heap allocations
    2. UTF8 types maintain their natural sort order when stored as binary arrays.
    
    DRILL-3492 - Remove test code that creates test tables with UTF8 OrderedByte encoding.

    - made the constructor for TopLevelAllocator package private to enforce this
    
    Delete a test that had been commented out for over a year, it no longer compiles due to interface changes and there is plenty of other testing for hash aggregate.
