dev-cpp/antlr-cpp: New package, split from dev-java/antlr

The old ANTLR 2 ebuild tried to cram all the runtimes together, which
was messy. The C++ runtime does not need any Java components at build
time or runtime so it makes sense to split this out. The C++ runtime
for ANTLR 4 is maintained separately by upstream anyway.

This new package does a better job of building the shared library with
the help of libtool. It also supports multilib.

+# Upstream only installs a static library. The original antlr ebuild
+# built a shared library manually, which isn't so great either. This
+# ebuild applies libtool instead and therefore an autoreconf is
+# required. A couple of errors concerning tr have been seen but the
+# final result still looks good. This also sidesteps bug #554344 plus
+# the need to call einstall.
