Hide java_init, java_exit functions. Deprecate java_new, java_set, java_get. * ov-java.cc: Rename java_init, java_exit to internal versions __java_init__, __java_exit__. Remove java_new. Rename java_set, java_get to __java_set__, __java_get__. Use #ifdef HAVE_JAVA blocks to compile the docstrings for Java functions regardless of whether Java is present. Use Octave coding conventions. * scripts/deprecated/java_get.m, scripts/deprecated/java_new.m, scripts/deprecated/java_set.m: Create new scripts to issue a warning about deprecated functions. * scripts/deprecated/module.mk: Add new deprecated scripts to build system.
