This should compile -Werror-clean, at least on Darwin, and I'd hope on GNU/Linux as well. If some of you have other Unix setups and feel like testing this, please do, and report any problems to me.

* configure.ac (--enable-local-sockets): new enable argument.
(ENABLE_LOCAL_SOCKETS): new define.
* native/jni/java-net/Makefile.am (local_sources): new variable.
(lib_javanet_la_SOURCES): append `local_sources.'
* native/jni/java-net/gnu_java_net_local_LocalSocketImpl.c,
* native/jni/java-net/local.c,
* native/jni/java-net/local.h,
* include/gnu_java_net_local_LocalSocketImpl.h,
