    hs: Expose hs_service.c functions for unit tests
    
    In order to avoid src/or/hs_service.o to contain no symbols and thus making
    clang throw a warning, the functions are now exposed not just to unit tests.

+  o Minor bugfix (compilation):
+    - Functions in hs_service.c was only compiled for unit test making the
+      created object (.o) contain no symbols in src/or/libor.a resulting in a
+      compilation warning from clang. We now expose those functions for the
+      unit tests. This will be changed in 0.3.2 release. Fixes bug 21825.;
+      bugfix on tor-0.3.0.1-alpha.
