Change subject: IMPALA-5717: Support for reading ORC data files
......................................................................


Patch Set 17:

Sorry that I find a bug in this patch. Please wait until I fix it. Repro:

 hive> create table tmp_orc (a int, b string, c int) stored as orc;
 hive> insert overwrite table tmp_orc select 1, "abc", 2;
 impala> invalidate metadata tmp_orc;
 impala> select * from tmp_orc;
 hive> insert overwrite table tmp_orc select 3, "ccc", 3;
 impala> refresh tmp_orc;
 impala> select * from tmp_orc;

The orc lib reports that ORC postscript length is invalid in the final query.
