[REFACTOR] Switch to maven.

Move files to maven structure, using the following script:

function do-mv() {
  if [ -f $2 -o -d $2 ]; then
    echo "Already moved: $2"
    return
  fi
  mkdir -p $(dirname $2)
  git mv "$1" "$2"
}

do-mv src/main/mondrian/parser/MdxParser.jj src/main/javacc/mondrian/parser/MdxParser.jj
for i in $(find testsrc -name \*.xml -o -name \*.csv -o -name \*.properties); do
  do-mv $i $(echo $i | sed -e 's!testsrc/main!src/test/resources!')
done
do-mv src/main/META-INF src/main/resources/META-INF
do-mv src/main/OSGI-INF src/main/resources/OSFI-INF
do-mv src/main/mondrian src/main/java/mondrian
do-mv src/main/overview.html src/main/java/overview.html

rmdir testsrc/queryFiles
rmdir testsrc/pendingQueryFiles

do-mv testsrc/main src/test/java
do-mv src/main/mondrian/olap/Mondrian3Schema.xml src/main/xom/mondrian/olap/Mondrian3Schema.xml
do-mv src/main/mondrian/olap/MondrianSchema.xml src/main/xom/mondrian/olap/MondrianSchema.xml
do-mv src/main/mondrian/rolap/aggmatcher/DefaultRules.xml src/main/xom/mondrian/rolap/aggmatcher/DefaultRules.xml
do-mv src/main/mondrian/rolap/aggmatcher/DefaultRulesSchema.xml src/main/xom/mondrian/rolap/aggmatcher/DefaultRulesSchema.xml
do-mv src/main/mondrian/xmla/DataSourcesConfig.xml src/main/xom/mondrian/xmla/DataSourcesConfig.xml
do-mv src/main/mondrian/olap/MondrianProperties.xml src/main/prop/mondrian/olap/MondrianProperties.xml

Maven calls out to ant for various code generation tasks. I have changed
build.xml for the new file structure, so I believe that you can use ant
as before, but I haven't checked.

Most tests pass. I haven't checked whether the failure rate is the same as
on lagunitas branch using ant.

Intellij is able to read the pom.xml, populate a workspace, and run tests,
so I have obsoleted Intellij project files.

[BISERVER-11504] Fixing the location of the blueprint beans file (typo in restructure). Also converting to pure Blueprint namespaces and syntax as Karaf does not support Gemini in the 2.x codeline that we're using. Finally declaring a version of log4j in import to prevent the use of an older version of the api also available in Karaf
