Instead of having the IconTheme have a hashtable that owns individual strings and then IconThemeDirSize have a similar hash (but with the strings owned by the other hash), we have a consecutive memory chunks where we store the icon names and then the hashtable has pointers into this. This means we can avoid a bunch of individual strdup()s in a way that is less fragmented and wastes less space. Additionally, since we do an initial lookup anyway we have the internalized icon name during lookup which means we can use g_direct_hash/equal instead of g_str_hash/equal making the lookup faster too.
