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.
