[SPARK-3970] Remove duplicate removal of local dirs

The shutdown hook of `DiskBlockManager` would remove localDirs. So do not need to register them with `Utils.registerShutdownDeleteDir`. It causes duplicate removal of these local dirs and corresponding exceptions.

[SPARK-4030] Make destroy public for broadcast variables

This change makes the destroy function public for broadcast variables. Motivation for the change is described in https://issues.apache.org/jira/browse/SPARK-4030.
This patch also logs where destroy was called from if a broadcast variable is used after destruction.

SPARK-2621. Update task InputMetrics incrementally

The patch takes advantage an API provided in Hadoop 2.5 that allows getting accurate data on Hadoop FileSystem bytes read.  It eliminates the old method, which naively accepts the split size as the input bytes.  An impact of this change will be that input metrics go away when using against Hadoop versions earlier thatn 2.5.  I can add this back in, but my opinion is that no metrics are better than inaccurate metrics.

This is difficult to write a test for because we don't usually build against a version of Hadoop that contains the function we need.  I've tested it manually on a pseudo-distributed cluster.

[SQL] Fixes caching related JoinSuite failure

PR #2860 refines in-memory table statistics and enables broader broadcasted hash join optimization for in-memory tables. This makes `JoinSuite` fail when some test suite caches test table `testData` and gets executed before `JoinSuite`. Because expected `ShuffledHashJoin`s are optimized to `BroadcastedHashJoin` according to collected in-memory table statistics.

This PR fixes this issue by clearing the cache before testing join operator selection. A separate test case is also added to test broadcasted hash join operator selection.

TRUNCATE TABLE table_name [PARTITION partition_spec];
partition_spec:
  : (partition_col = partition_col_value, partition_col = partiton_col_value, ...)
Removes all rows from a table or partition(s). Currently target table should be native/managed table or exception will be thrown. User can specify partial partition_spec for truncating multiple partitions at once and omitting partition_spec will truncate all partitions in the table.

[SPARK-4107] Fix incorrect handling of read() and skip() return values

`read()` may return fewer bytes than requested; when this occurred, the old code would silently return less data than requested, which might cause stream corruption errors.  `skip()` faces similar issues, too.

This patch fixes several cases where we mis-handle these methods' return values.
