This should be 2014 (the date the spec was first written).

It's unlikely to matter though - this is for the MESA_EXTENSION_MAX_YEAR
hack which allows users to stop exposing extensions past a certain year,
which is rarely used.  (It's to work around old buggy GL apps that used
a fixed size buffer for the extension string, so exposing too many
extensions would trigger the buffer overflow in their game.)
