efreet: Add parameter checking to exported API

Some efreet APIs do not check input parameters.  So I add checking by
using EINA_SAFETY_ON_XXX().
ISO/IEC statndards says that "If an argument to a function has an
invalid value, behavior is undefined" . But this is  just for the
primitive functions such as libc.  I think that parameter checking is
needed in at least EFL exported APIs to prevent run-time abnormal
behavior.
EINA_SAFTETY_ON_XXX are better than "if (xxx) return" because it gives
error message and can be maintainable.
