MAPREDUCE-7315. LocatedFileStatusFetcher to collect/publish IOStatistics. (#2579) 
Part of the HADOOP-16830 IOStatistics API feature.

If the source FileSystem's listing RemoteIterators
implement IOStatisticsSource, these are collected and served through
the IOStatisticsSource API. If they are not: getIOStatistics() returns
null.

Only the listing statistics are collected; FileSystem.globStatus() doesn't
provide any, so IO use there is not included in the aggregate results.

Contributed by Steve Loughran.

8f60a90688 HADOOP-17125. Use snappy-java in SnappyCodec (#2297) 
This switches the SnappyCodec to use the java-snappy codec, rather than the native one.

To use the codec, snappy-java.jar (from org.xerial.snappy) needs to be on the classpath.

This comesin as an avro dependency,  so it is already on the hadoop-common classpath,
as well as in hadoop-common/lib.
The version used is now managed in the hadoop-project POM; initially 1.1.7.7

HADOOP-16458. LocatedFileStatusFetcher.getFileStatuses failing intermittently with S3 
Contributed by Steve Loughran.

Includes
-S3A glob scans don't bother trying to resolve symlinks
-stack traces don't get lost in getFileStatuses() when exceptions are wrapped
-debug level logging of what is up in Globber
-Contains HADOOP-13373. Add S3A implementation of FSMainOperationsBaseTest.
-ITestRestrictedReadAccess tests incomplete read access to files.

This adds a builder API for constructing globbers which other stores can use
so that they too can skip symlink resolution when not needed.

HADOOP-15229. Add FileSystem builder-based openFile() API to match createFile(); 
S3A to implement S3 Select through this API.

The new openFile() API is asynchronous, and implemented across FileSystem and FileContext.

The MapReduce V2 inputs are moved to this API, and you can actually set must/may
options to pass in.

This is more useful for setting things like s3a seek policy than for S3 select,
as the existing input format/record readers can't handle S3 select output where
the stream is shorter than the file length, and splitting plain text is suboptimal.
Future work is needed there.

In the meantime, any/all filesystem connectors are now free to add their own filesystem-specific
configuration parameters which can be set in jobs and used to set filesystem input stream
options (seek policy, retry, encryption secrets, etc).
