Try to restore PyString_FromStringAndSize in RealDisplaySizeMM.c (with proper Unicode version)

[eoyilmaz]

To fix the code from raising errors and not doing what it suppose to do, the PyString_FromStringAndSize has been replaced with PyString_FromString. I'm not experienced with C-Extension stuff, so it might broke something:

The following is replaced:

            if (dp[i]->edid_len > 0 && dp[i]->edid != NULL &&
               (value = PyString_FromStringAndSize(dp[i]->edid, dp[i]->edid_len)) != NULL) {
                PyDict_SetItemString(d, "edid", value);
            }

with:

            if (dp[i]->edid_len > 0 && dp[i]->edid != NULL &&
                (value = PyString_FromString(dp[i]->edid)) != NULL) {
                PyDict_SetItemString(d, "edid", value);
            }

Investigate what is the expected output and what we are getting currently.
