[RFAv2 1/3] Use function_name_style to print Ada and C function names

[Philippe Waroquiers]

Note that ada-typeprint.c print_func_type is called with
types representing functions and is also called to print
a function NAME and its type.  In such a case, the function
name will be printed using function name style.

Similarly, c_print_type_1 is called to print a type, optionally
with the name of an object of this type in the VARSTRING arg.
So, c_print_type_1 uses function name style to print varstring
when the type code indicates that c_print_type_1 TYPE is some
'real code'.

2019-01-12  Philippe Waroquiers  <philippe.waroquiers@skynet.be>

	* ada-typeprint.c (print_func_type): Print function name
	style to print function name.
	* c-typeprint.c (c_print_type_1): Likewise.
