The import of protobuf-java-2.5 in the hadoop-yarn-api module
is downgraded from "compile" to "provided"
This removes it from share/hadoop/yarn/lib/protobuf-java-2.5.0.jar
It is still found under
share/hadoop/yarn/timelineservice/lib/protobuf-java-2.5.0.jar

Followup to the previous HADOOP-18487 patch: changes the scope of
protobuf-2.5 in hadoop-common and elsewhere from "compile" to "provided".
This means that protobuf-2.5 is
* No longer included in hadoop distributions
* No longer exported by hadoop common POM files
* No longer exported transitively by other hadoop modules.
* No longer listed in LICENSE-binary.

Protobuf 2.5 JAR is no longer needed at runtime.
The option common.protobuf.scope defines whether the protobuf 2.5.0
dependency is marked as provided or not.
* New package org.apache.hadoop.ipc.internal for internal only protobuf classes
...with a ShadedProtobufHelper in there which has shaded protobuf refs
only, so guaranteed not to need protobuf-2.5 on the CP
* All uses of org.apache.hadoop.ipc.ProtobufHelper have
been replaced by uses of org.apache.hadoop.ipc.internal.ShadedProtobufHelper
* The scope of protobuf-2.5 is set by the option common.protobuf2.scope
In this patch is it is still "compile"
* There is explicit reference to it in modules where it may be needed.
* The maven scope of the dependency can be set with the common.protobuf2.scope
option. It can be set to "provided" in a build:
-Dcommon.protobuf2.scope=provided
* Add new ipc(callable) method to catch and convert shaded protobuf
exceptions raised during invocation of the supplied lambda expression
* This is adopted in the code where the migration is not traumatically
over-complex. RouterAdminProtocolTranslatorPB is left alone for this
reason.

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
