kdb: kdb_support: Fix debugging information problem

There are several common patterns.

0:
        kdb_printf("...",...);

which is the normal one.

1:
        kdb_printf("%s: "...,__func__,...)

We could improve '1' to this :

        #define kdb_func_printf(format, args...) \
                kdb_printf("%s: " format, __func__, ## args)

2:
        if(KDB_DEBUG(AR))
                kdb_printf("%s "...,__func__,...);

We could improve '2' to this :
        #define kdb_dbg_printf(mask, format, args...) \
                do { \
                        if (KDB_DEBUG(mask)) \
                                kdb_func_printf(format, ## args); \
                } while (0)

In addition, we changed the format code of size_t to %zu.
