acinclude.m4: add a check defining va_copy macro when needed.
vasprintf.c: use TMP_ALLOC instead of variable-length array (C99).
tests/tfprintf.c tests/tsprintf.c: #define length of array instead of const int so as to avoid variable-length array (C99).
tests/tprintf.c: #define length of array instead of const int so as to avoid variable-length array (C99).
remove use of function dup (dependency with <unistd.h>).
