Not sure, but if I read TAP spec correctly, it doesn't strictly define
that it should beon the first line, rather appear only once at the start
or at the end (if the number of test points is not known).

So if tcnt for the test plan, what is 'acnt' for? ... I didn't find the
analogy in the TAP spec.

Looking at the 'struct tst_test',

* the names like 'tcnt' and 'acnt' seem not clear. May be we should name 
'tcnt' as
test_planor test_count?

* also, why bitfields in the struct tst_test have different number of 
storage bits?

   int needs_tmpdir:1;
   int needs_root:2;
   int forks_child:3;
   int needs_device:4;
   int needs_checkpoints:5;

if their value is just '0' or '1', ':1' - should be instead.
