[cogl-color] Adds a cogl_color_equal() function

Browse Source 
CoglColors shouldn't be compared using memcmp since they may contain
uninitialized padding bytes.

The prototype is also suitable for passing to g_hash_table_new as the
key_equal_func.

_cogl_pango_display_list_add_texture now uses this instead of memcmp.
