Small tweaks to make debugging failing testcases easier
Two things to make debugging easier: - Use an fflush() after each verbose_printf(), so that line buffering won't mean messages get re-ordered w.r.t. the operations they're describing (this can be particularly confusing when straceing a testcase). - When quiet mode isn't on, print the testname and pid at the beginning of each test from test_init(). This saves a few steps finding the pid when attaching gdb, or strace, or examining /proc/XX/maps.
