Closes #9065 from trystanleftwich/SPARK-11052.

Currently if it isn't set it scans `/lib/*` and adds every dir to the
classpath which makes the env too large and every command called
afterwords fails.

- pass `$ZINC_PORT` to zinc status/shutdown commands
- fix path check that sets `$ZINC_INSTALL_FLAG`, which was incorrectly
  causing zinc to be shutdown and restarted every time (with mismatched
  ports on those commands to boot)
- pass `-DzincPort=${ZINC_PORT}` to maven, to use the correct zinc port
  when building

Versions of Maven older than 3.3.0 apparently have [a bug in how they handle transitive dependencies](https://github.com/apache/spark/pull/6492#issuecomment-111001101).

I confirmed that upgrading to Maven 3.3.3 resolves at least the particular manifestation of this bug that I ran into.

I've seen out of memory exceptions when trying
to run many parallel builds against the same Zinc
server during packaging. We should use the same
increased memory settings we use for Maven itself.

I tested this and confirmed that the Nailgun JVM
launched with higher memory.

a398324 [GuoQiang Li] curl should support URL redirection in build/mvn

When we use `make-distribution.sh` with `--with-tachyon` option, Tachyon will be downloaded by `wget` command but some systems don't have `wget` by default (MacOS X doesn't have).
Other scripts like build/mvn, build/sbt support not only `wget` but also `curl` so `make-distribution.sh` should support `curl` too.

Recently, build/mvn and build/sbt are added, and sbt/sbt is changed but there are no license headers. Should we add license headers to the scripts right?
If it's not right, please let me correct.

This PR doesn't affect behavior of Spark, I don't file in JIRA.

1abc972 [Kousuke Saruta] Added LICENSE Header

Creates a top level directory script (as `build/mvn`) to automatically download zinc and the specific version of scala used to easily build spark. This will also download and install maven if the user doesn't already have it and all packages are hosted under the `build/` directory. Tested on both Linux and OSX OS's and both work. All commands pass through to the maven binary so it acts exactly as a traditional maven call would.
