Add Hive Metastore (0.13.1) Compiled with Thrift 0.9.2

https://github.com/apache/hive/blob/release-0.13.1/metastore/if/hive_metastore.thrift
Remove `\metastore\HiveObjectType`

`\metastore\HiveObjectType` is broken because we can't use reserved names like
`GLOBAL` in PHP class constants. We don't use `\metastore\HiveObjectType` (yet)
so just comment it out. This problem is an result of a Thrift
[bug](https://issues.apache.org/jira/browse/THRIFT-1209).
Rename `\metastore\Function` to `\metastore\HiveFunction`

Another case of a reserved PHP word used in the Hive Thrift interface causing
broken code.
