Max c59ef12e51 AllocTest: expand test output
* print MS classes
* unify and print test mode description
* print additional info on test completion

This only changes meta info about test run but not the actual test
output.

Max 2ecf0fdfc2 AllocTest: adjust test_alloc_b()
This function contains 3 independent test cases. Let's split them into
separate functions to simplify further modifications:

* split test cases into separate functions
* use them for mass test as well
* change function names to avoid confusion
* make individual test cases return error instead of failing via assert
  on allocation failure

The top-level test_alloc_b() is used as part of exhaustion tests in
test_all_alloc_b() for example, so it's expected that allocation might
fail (due to TFI or USF exhaustion for example) eventually. In this case
it's better to indicate it to caller instead of failing entire program.

The test output does not require any adjustements because we do not
exhaust to the point of allocation failure yet.

The code in create_dl_acked_block() has underlying assumption that
rlc.num_data_blocks can never be more than 2, which is true and is
enforced by appropriate asserts but is not obvious when looking at the
function code alone. It's equally hard for Coverity which leads to false
positives in scan.

Lets' make this assumption explicit by putting it into for(;;) condition
alongside with corresponding comment.
