Prefixing getters with C name of the interface is just
redundant since it is the same as the name of the structure
that contains those fields.

The following structure:
struct test_pilot {
  $type test_pilot_get_name;
}

changes to:
struct test_pilot {
  $type get_name;
}

Properties are single value of a small number of predefined D-Bus
types. There is no need to generate them with codegen. Actually,
the source generator for property getters is already quite mess
with branching for array, strings and object paths. Adding any
more complex type in the future (such as dictionary) would require
even more branching or creating a separate path for it.

Hard coding the getters will simplify creating new ones for more
complex types. This patch also reduces lots of code duplication
and creates a simple function for GetAll.

is an object name. It will return the part unescaped.
