HADOOP-12994 patch 003
-address chris's concerns
-add an option for supports positioned readable; default is driven by "supports
seek"
-split up test operations into separate test cases
-tested on local, hdfs, s3 filesystems
I've caught the EOF in Azure and downgraded to a -1, but not tested it...my ASF
MSDN sub hasn't renewed; I'm chasing that up, and am currently azureless

> Some work on S3a has shown up that there aren't tests catching regressions in
> readFully, reviewing the documentation shows that its specification could be
> improved.

> # review the implementations
> # add tests (proposed: to the seek contract; streams which support seek
> should support positioned readable)
> # fix code, where it differs significantly from HDFS or LocalFS
