add: use advise function to display hints

Use the advise function in advice.c to display hints to the users, as it provides a neat and a standard format for hint messages, i.e: the text is colored in yellow and the line starts by the word "hint:". Also this will enable us to control the messages using advice.* configuration variables. Signed-off-by: Heba Waly <heba.waly@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
