Add proguard 5.3.3 to third_party.

See bazelbuild#3777

The Android SDK provides a very old proguard and will be removing it
soon, so we need to bundle our own.

+ProGuard, Java class file shrinker, optimizer, obfuscator, and preverifier
+==========================================================================
+
+This distribution contains the following directories:
+
+- bin          : simple wrapper scripts to run ProGuard, its GUI, and ReTrace
+- lib          : the main jars, compiled and ready to use with "java -jar ...."
+- docs         : the complete documentation, licenses, etc. in html format
+- examples     : some example configuration files
+- src          : the source code
+- buildscripts : various alternative build scripts
+
+
+The best place to start is docs/index.html
+
+
+Example
+-------
+
+If you want to give ProGuard a spin right away, try processing the ProGuard
+jar itself:
+
+    cd examples
+    java -jar ../lib/proguard.jar @proguard.pro
+
+The resulting proguard_out.jar contains the same application, but it's a lot
+smaller.
+
+Enjoy!

+ProGuard, Java class file shrinker, optimizer, obfuscator, and preverifier
+==========================================================================
+
+This directory contains a number of alternative ways to build ProGuard:
+
+- build.sh      : a shell script for GNU/Linux
+- makefile      : a makefile for GNU/Linux
+- build.gradle  : a Gradle build file for all platforms
+- build.xml     : an Ant build file for all platforms
+- maven/pom.xml : a Maven POM for building the Maven artifacts
+
+- As a final alternative, you can also easily compile the code from the
+  command line:
+
+    mkdir classes
+    javac -sourcepath src -d classes src/proguard/ProGuard.java
+    javac -sourcepath src -d classes src/proguard/gui/ProGuardGUI.java
+    javac -sourcepath src -d classes src/proguard/retrace/ReTrace.java
+
+  For the ProGuard Gradle task:
+
+    javac -sourcepath src -d classes -classpath ..... \
+        src/proguard/gradle/ProGuardTask.java
+
+  For the ProGuard Ant task:
+
+    javac -sourcepath src -d classes -classpath lib/ant.jar \
+        src/proguard/ant/ProGuardTask.java
+
+  For the Java Micro Edition Wireless Tool Kit (JME WTK) obfuscator plug-in:
+
+    javac -sourcepath src -d classes -classpath wtklib/kenv.zip \
+        src/proguard/wtk/ProGuardObfuscator.java
+
+Depending on the scripts, you may still need to install Gradle, Ant, Maven,
+and the JME WTK yourself.
+
+Enjoy!
