HADOOP-16202. Enhanced openFile(): mapreduce and YARN changes. (#2584/2)
These changes ensure that sequential files are opened with the
right read policy, and split start/end is passed in.

As well as offering opportunities for filesystem clients to
choose fetch/cache/seek policies, the settings ensure that
processing text files on an s3 bucket where the default policy
is "random" will still be processed efficiently.

This commit depends on the associated hadoop-common patch,
which must be committed first.
