Wenchen Fan 84a3399908 [SPARK-18028][SQL] simplify TableFileCatalog ... ## What changes were proposed in this pull request? Simplify/cleanup TableFileCatalog: 1. pass a `CatalogTable` instead of `databaseName` and `tableName` into `TableFileCatalog`, so that we don't need to fetch table metadata from metastore again 2. In `TableFileCatalog.filterPartitions0`, DO NOT set `PartitioningAwareFileCatalog.BASE_PATH_PARAM`. According to the [classdoc](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/PartitioningAwareFileCatalog.scala#L189-L209), the default value of `basePath` already satisfies our need. What's more, if we set this parameter, we may break the case 2 which is metioned in the classdoc. 3. add `equals` and `hashCode` to `TableFileCatalog` 4. add `SessionCatalog.listPartitionsByFilter` which handles case sensitivity. ## How was this patch tested? existing tests.
