[webkit-efl] Make _ref() functions return the ref'd object

[Dumez, Christophe]

Hi,

I would like to notify you that I'm landing a patch [1] to change the
prototype of our *_ref() functions so that they now return the object being
ref'd.

This makes them more convenient to use:

e.g. the following:
  ewk_download_job_ref(ewkDownload);
  ewkContext->downloadJobs.add(downloadId, ewkDownload);

is replaced by:
  ewkContext->downloadJobs.add(downloadId, ewk_download_job_ref(ewkDownload));


This is consistent with both eina_stringshare_ref() in EFL and
g_object_ref() in glib.

Note that I have updated the EFL coding style wiki [2] to reflect this
change.
Please keep this in mind when you add new _ref() functions or when adding
new code that uses them.
