dawgdic: new package

The dawgdic package provides object files and utilities for building
and accessing directed acyclical word graph (DAWG) dictionaries.

This version of the patch uses the updated GitHub dawgdic repo instead
of the Google Code repo used in the previous version of this patch.

[Thomas:
  - use the github macro for <pkg>_SITE
  - remove <pkg>_SITE_METHOD, useless once you use the github macro
    for <pkg>_SITE
  - fix the license, it is BSD-3c and not GPLv3
  - remove commented <pkg>_SITE in the .mk file
  - add missing dependency on C++.]

+	  dawgdic provides a library for building and accessing
+	  dictionaries implemented with directed acyclic word graphs
+	  (DAWG). A dawg is constructed by minimizing a trie as a
+	  deterministic finite automaton (DFA), and thus the dawg has
+	  an advantage in memory usage. In addition, dawgdic uses a
+	  double-array as a base data structure, so its retrieval
+	  speed is as fast as that of Darts, a library for building
+	  and accessing double-array tries.
