[cairo] change family parameter to const

[Andrew Chant]

Hi,
 This patch changes family from a char * to a const char * for functions
 which take a parameter for the family of a font being selected.
 It allows you to simply pass constant strings to cairo_select_font.  Please let me know if I missed any important functions, and feel free to ignore this patch if it is useless/will cause problems.


functions affected:
 cairo_select_font
 _cairo_font_create
 _cairo_ft_font_create
 _cairo_gstate_select_font
