* Add missing asserts to exported functions.
* Unify formatting.
* Fix the gtk-doc comment for ld_symbol_category_set_human_name().
* Make ld_library_load() reflect it's declaration.
* Remove an unused variable in ld_library_load_cb().
* Change all char's to gchar's.
This step is needed, since the current design is quite chaotic
and it would not be possible to finish the application.
There's still a lot to be done.
After this step, it's time to implement the rest of LdLua.
