Danny Al-Gaaf 59aad34795 configure.ac: check for org.junit.rules.ExternalResource
Check for org.junit.rules.ExternalResource if build with
--enable-cephfs-java and --with-debug. Checking for junit4
isn't enough since junit4 has this class not before 4.7.

Added some m4 files to get some JAVA related macros. Changed
autogen.sh to work with local m4 files/macros.

dnl AC_TRY_COMPILE_JAVA attempt to compile user given source.

dnl *Warning*: its success or failure can depend on a proper setting of
dnl the CLASSPATH env. variable.

dnl Note: This is part of the set of autoconf M4 macros for Java
dnl programs. It is VERY IMPORTANT that you download the whole set,
dnl some macros depend on other. Unfortunately, the autoconf archive
dnl does not support the concept of set of macros, so I had to break it
dnl for submission. The general documentation, as well as the sample
dnl configure.in, is included in the AC_PROG_JAVA macro.
