Vendor jarjar instead of using a binary version of it.

It appears that jarjar is not actually used except for renaming classes
in the coverage collecting Java test runner as verified by

`find . -name BUILD | xargs grep jarjar`

Yak shaving for #2820.

This is necessary because the current version of jarjar does not work
with Java 8 classes because it embeds a version of ASM that doesn't
support that yet.

+Jar Jar Links is a utility that makes it easy to repackage Java
+libraries and embed them into your own distribution. This is useful
+for two reasons:
+
+You can easily ship a single jar file with no external dependencies.
+
+You can avoid problems where your library depends on a specific
+version of a library, which may conflict with the dependencies of
+another library.
+
+How does it work?
+
+Jar Jar Links includes an Ant task that extends the built-in jar
+task. The normal zipfileset element is used to embed jar files. A
+new rule element is added which uses wildcards patterns to rename
+the embedded class files. Bytecode transformation (via ASM) is used
+to change references to the renamed classes, and special handling is
+provided for moving resource files and transforming string literals.
+
+Using with ant
+--------------
+
+In our imaginary project, the Ant "jar" target looks like:
+
+```
+<target name="jar" depends="compile">
+    <jar jarfile="dist/example.jar">
+        <fileset dir="build/main"/>
+    </jar>
+</target>
+```
+
+To use Jar Jar Links, we define a new task named "jarjar", and
+substitute it wherever we used the jar task. Because the JarJarTask
+class extends the normal Ant Jar task, you can use jarjar without
+any of its additional features, if you want:
+
+```
+<target name="jar" depends="compile">
+    <taskdef name="jarjar" classname="com.tonicsystems.jarjar.JarJarTask"
+        classpath="lib/jarjar.jar"/>
+    <jarjar jarfile="dist/example.jar">
+        <fileset dir="build/main"/>
+    </jarjar>
+</target>
+```
+
+Just like with the "jar" task, we can include the contents of another
+jar file using the "zipfileset" element. But simply including another
+projects classes is not good enough to avoid jar hell, since the class
+names remain unchanged and can still conflict with other versions.
+
+To rename the classes, JarJarTask adds a new "rule" element. The
+rule takes a "pattern" attribute, which uses wildcards to match
+against class names, and a "result" attribute, which describes how
+to transform the matched names.
+
+In this example we include classes from jaxen.jar and add a rule
+that changes any class name starting with "org.jaxen" to start with
+"org.example.jaxen" instead (in our imaginary world we control the
+example.org domain):
+
+```
+<target name="jar" depends="compile">
+    <taskdef name="jarjar" classname="com.tonicsystems.jarjar.JarJarTask"
+        classpath="lib/jarjar.jar"/>
+    <jarjar jarfile="dist/example.jar">
+        <fileset dir="build/main"/>
+        <zipfileset src="lib/jaxen.jar"/>
+        <rule pattern="org.jaxen.**" result="org.example.@1"/>
+    </jarjar>
+</target>
+```
+
+The ** in the pattern means to match against any valid package
+substring. To match against a single package component (by excluding
+dots (.) from the match), a single * may be used instead.
+
+The @1 in the result is a reference to the ** portion of the rule. For
+every * or ** in the rule, a numbered reference is available for use
+in the result. References are numbered from left to right, starting
+with @1, then @2, and so on.
+
+The special @0 reference refers to the entire class name.
+
+Using with gradle
+-----------------
+
+```
+	dependencies {
+		// Use jarjar.repackage in place of a dependency notation.
+		compile jarjar.repackage {
+			from 'com.google.guava:guava:18.0'
+
+			classDelete "com.google.common.base.**"
+
+			classRename "com.google.**" "org.private.google.@1"
+		}
+	}
+```
+
+See (jarjar-gradle/example/build.gradle) for some complete examples.
+
+Using from the command line
+---------------------------
+
+From the command-line
+
+```
+java -jar jarjar.jar [help]
+```
+
+Prints this help message.
+
+```
+java -jar jarjar.jar strings <cp>
+```
+
+Dumps all string literals in classpath `<cp>`. Line numbers will be
+included if the classes have debug information.
+
+```
+java -jar jarjar.jar find <level> <cp1> [<cp2>]
+```
+
+Prints dependencies on classpath `<cp2>` in classpath `<cp1>`. If `<cp2>`
+is omitted, `<cp1>` is used for both arguments.
+
+The level argument must be class or jar. The former prints dependencies
+between individual classes, while the latter only prints jar->jar
+dependencies. A "jar" in this context is actually any classpath
+component, which can be a jar file, a zip file, or a parent directory
+(see below).
+
+```
+java -jar jarjar.jar process <rulesFile> <inJar> <outJar>
+```
+
+Transform the `<inJar>` jar file, writing a new jar file to `<outJar>`. Any
+existing file named by `<outJar>` will be deleted.
+
+The transformation is defined by a set of rules in the file specified
+by the rules argument (see below).  Classpath format
+
+The classpath argument is a colon or semi-colon delimited
+set (depending on platform) of directories, jar files,
+or zip files. See the following page for more details:
+http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/classpath.html
+
+Mustang-style wildcards are also supported:
+http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6268383 Rules
+file format
+
+The rules file is a text file, one rule per line. Leading and trailing
+whitespace is ignored. There are three types of rules:
+
+```
+rule <pattern> <result>
+zap <pattern>
+keep <pattern>
+```
+
+The standard rule (rule) is used to rename classes. All references to
+the renamed classes will also be updated. If a class name is matched
+by more than one rule, only the first one will apply.
+
+`<pattern>` is a class name with optional wildcards. `**` will match
+against any valid class name substring. To match a single package
+component (by excluding . from the match), a single `*` may be used
+instead.
+
+`<result>` is a class name which can optionally reference the substrings
+matched by the wildcards. A numbered reference is available for every
+`*` or `**` in the `<pattern>`, starting from left to right: @1, @2, etc. A
+special @0 reference contains the entire matched class name.
+
+The zap rule causes any matched class to be removed from the resulting
+jar file. All zap rules are processed before renaming rules.
+
+The keep rule marks all matched classes as "roots". If any keep rules
+are defined all classes which are not reachable from the roots via
+dependency analysis are discarded when writing the output jar. This
+is the last step in the process, after renaming and zapping.

+Jar Jar Links - A utility to repackage and embed Java libraries
+Copyright 2007 Google Inc.
+
+Command-line usage:
+
+  java -jar jarjar.jar [help]
+
+    Prints this help message.
+
+  java -jar jarjar.jar strings <cp>
+
+    Dumps all string literals in classpath <cp>. Line numbers will be
+    included if the classes have debug information.
+
+  java -jar jarjar.jar find <level> <cp1> [<cp2>]
+
+    Prints dependencies on classpath <cp2> in classpath <cp1>. If <cp2>
+    is omitted, <cp1> is used for both arguments.
+
+    The level argument must be "class" or "jar". The former prints
+    dependencies between individual classes, while the latter only
+    prints jar->jar dependencies. A "jar" in this context is actually
+    any classpath component, which can be a jar file, a zip file, or a
+    parent directory (see below).
+
+  java -jar jarjar.jar process <rulesFile> <inJar> <outJar>
+
+    Transform the <inJar> jar file, writing a new jar file to <outJar>.
+    Any existing file named by <outJar> will be deleted.
+
+    The transformation is defined by a set of rules in the file specified
+    by the rules argument (see below).
+
+Classpath format:
+
+  The classpath argument is a colon or semi-colon delimited set
+  (depending on platform) of directories, jar files, or zip files. See
+  the following page for more details:
+  http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/classpath.html
+  
+  Mustang-style wildcards are also supported:
+  http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6268383
+
+Rules file format:
+
+  The rules file is a text file, one rule per line. Leading and trailing
+  whitespace is ignored. There are three types of rules:
+
+    rule <pattern> <result>
+    zap <pattern>
+    keep <pattern>
+
+  The standard rule ("rule") is used to rename classes. All references
+  to the renamed classes will also be updated. If a class name is
+  matched by more than one rule, only the first one will apply.
+
+  <pattern> is a class name with optional wildcards. "**" will
+  match against any valid class name substring. To match a single
+  package component (by excluding "." from the match), a single "*" may
+  be used instead.
+
+  <result> is a class name which can optionally reference the
+  substrings matched by the wildcards. A numbered reference is available
+  for every "*" or "**" in the <pattern>, starting from left to
+  right: "@1", "@2", etc. A special "@0" reference contains the entire
+  matched class name.
+
+  The "zap" rule causes any matched class to be removed from the resulting
+  jar file. All zap rules are processed before renaming rules.
+
+  The "keep" rule marks all matched classes as "roots". If any keep
+  rules are defined all classes which are not reachable from the roots
+  via dependency analysis are discarded when writing the output
+  jar. This is the last step in the process, after renaming and zapping.
