Add test for the estream printf functions
* tests/t-printf.c: New.
* configure.ac: Check for vasprintf.

These tests have been taken from Libestream and changed to be more
portable. For example there is only va_start per function and the
test return an error only for _GLIBC_ based systems because that is
what we compare against.
