Printf: Implement size checked and va_list variants #4683

  1. Printf: Implement size checked and va_list variants 

    tfp_snprintf(), tfp_vsprintf() and tfp_vsnprintf

Mark all the functions as accepting a format string.

Also, drop the #define's for printf() and snprintf() and call
them explicitely, since #defining printf messes up with
__attribute__ ((format (printf, X, Y)))

  2. All: Fix warnings reported by -Wformat 

    Since the tfp_printf() functions now have format attributes, the
format of the string has to match the arguments.
