Change `napi_callback` to return `napi_value` directly instead of requiring `napi_set_return_value`. When we invoke the callback, we will check the return value and call `SetReturnValue` ourselves. If the callback returns `NULL`, we don't set the return value in v8 which would have the same effect as previously if the callback didn't call `napi_set_return_value`. Seems to be a more natural way to handle return values from callbacks. As a consequence, remove `napi_set_return_value`. Add a `napi_value` to `napi_property_descriptor` to support string values which couldn't be passed in the `utf8name` parameter or symbols as property names. Class names, however, cannot be symbols so this `napi_value` must be a string type in that case. Remove all of the `napi_callback_info` helpers except for `napi_get_cb_info` and make all the parameters to `napi_get_cb_info` optional except for argc. Update all the test collateral according to these changes. Also add `test/addons-napi/common.h` to house some common macros for wrapping N-API calls and error handling.
