Change subject: IMPALA-8561: Eliminate mtime=-1 for HDFS scan ranges (part 1)
......................................................................


Patch Set 3:

This fixes mtime plumbing. There will be another change to add some extra 
validation to HdfsParquetScanner::ProcessFooter() when we read a larger footer.

This passed core tests, I'm running exhaustive. I'm thinking through 
appropriate tests to add.
