Add automake support for building the Java library.
If java, javac, and ant are all available, the Java library will be built as part of the standard make target.

+A sample configure.in is at the end of this file. Each macro is
+documented by comments before its definition. Here is a summary:
+
+AX_PROG_JAVAC: finds a Java compiler
+AX_PROG_JAVA: finds a Java virtual machine
+AX_CHECK_CLASS: finds if we have the given class (beware of CLASSPATH!)
+AX_CHECK_RQRD_CLASS: finds if we have the given class and stops otherwise

+AX_PROG_JAVAC tests an existing Java compiler. It uses the environment
+variable JAVAC then tests in sequence various common Java compilers. For
+political reasons, it starts with the free ones.
+If you want to force a specific compiler:
+ - at the configure.in level, set JAVAC=yourcompiler before calling
+ AX_PROG_JAVAC
+ - at the configure level, setenv JAVAC
+You can use the JAVAC variable in your Makefile.in, with @JAVAC@.
+
+*Warning*: its success or failure can depend on a proper setting of the
+CLASSPATH env. variable.
+
+TODO: allow to exclude compilers (rationale: most Java programs cannot compile
+with some compilers like guavac).

+AX_PROG_JAVA tests an existing Java virtual machine. It uses the
+environment variable JAVA then tests in sequence various common Java
+virtual machines. For political reasons, it starts with the free ones.

+If you want to force a specific VM:

+ - at the configure level, setenv JAVA
+You can use the JAVA variable in your Makefile.in, with @JAVA@.
