Attachment: PIG-2362.6.patch
On trunk, if I compile with -Dhadoopversion=23 and I launch bin/pig -x local I
get the following error repeated continuously:
{code}

So I am unable to test if the new build works with Hadoop 23.
This patch produces a new file, pig-core.jar, in the top level directory.
pig-core.jar is just a copy of pig-0.11.0-SNAPSHOT.jar in build/.
This is done just for convenience. Once we get rid of compatibility we can
remove all the pig jars from the top level directory.
> Rework Ant build.xml to use macrodef instead of antcall

> Antcall is evil: http://www.build-doctor.com/2008/03/13/antcall-is-evil/
> We'd better use macrodef and let Ant build a clean dependency graph.
> http://ant.apache.org/manual/Tasks/macrodef.html
> Right now we do like this:
> {code}
> <target name="buildAllJars">
> <antcall target="buildJar">
> <param name="build.dir" value="jar-A"/>
> </antcall>
> <antcall target="buildJar">
> <param name="build.dir" value="jar-B"/>
> </antcall>
> <antcall target="buildJar">
> <param name="build.dir" value="jar-C"/>
> </antcall>
> </target>
> <target name="buildJar">
> <jar destfile="target/${build.dir}.jar" basedir="${build.dir}/classfiles"/>
> </target>
> {code}
> But it would be better if we did like this:
> {code}
> <target name="buildAllJars">
> <buildJar build.dir="jar-A"/>
> <buildJar build.dir="jar-B"/>
> <buildJar build.dir="jar-C"/>
> </target>
> <macrodef name="buildJar">
> <attribute name="build.dir"/>
> <jar destfile="target/${build.dir}.jar" basedir="${build.dir}/classfiles"/>
> </macrodef>
> {code}
