gnome-rr: Add gnome_rr_output_get_ids_for_edid()

To get the vendor/product/serial triplet from an output.
This is useful for output matching in gnome-settings-daemon.

Interesting.  How do you plan to use this from g-s-d?

(Is the vendor null-terminated, or should we allocate a 5-byte string and terminate it ourselves, for safety?)

See the patch in bug 677032

it's 3 letters, and it's null-terminated in decode_vendor_and_product_identification():
 63     info->manufacturer_code[3]  = '\0';

Oh, I see, you want to look at the "WAC" vendor.  Makes sense; go ahead with the change.
