eeda1f3f0f Unify type of dirty_for in info structs 
Reformat function that calculates how long cache/core is dirty
Update `dirty_for` types in functional tests

Values stored in info structs fields (both in cache and core structs)
are unsigned 64-bits ints but `dirty_for`s were unsigned 32-bits ints.

Use existing function to transform returned value to seconds.
Replace seconds stored in metadata with seconds.
Replacement was done if old value of replaced field was equal to zero.
Acquiring monotonic high precission timestamp is potentially
slow and it makes sense to compare the field's value
to zero before calling atomic function.

5e52ac4ef2 Rename 'printf' field name in logger ops to 'print'. 
Due the aggresive security checks in compiler 'printf' might be substituded with
'__printf_chk'. However it does not differentiate whether substituted string is
library function call whether field in structure.

By renaming field we prevent it to be unintentionally subustituted by the
preprocessor.

003d6505aa Fix leaky tests 
Fix some instance tracking to prevent Python-side objects from leaking
buffers.
Also, reduce min size of Cache instance (real minimum should be around ~~19MiB,
but we need to make it more deterministic and 20 MiB seems to be reasonable).

Still some stuff left to do, but it needs more investigation and, for
now, this should suffice just to enable some form of CI.

e5227cef89 Implement pyocf adapter with sample OCF test 
PyOCF is a tool written with testing OCF functionality in mind.
It is a Python3 (3.6 version required) package which wraps OCF
by providing Python objects in place of OCF objects (volumes, queues,
etc). Thin layer of translation between OCF objects and PyOCF objects
enables using customized behaviors for OCF primitives by subclassing
PyOCF classes.

This initial version implements only WT and WI modes and single,
synchronously operating Queue.

TO DO:

  - Queues/Cleaner/MetadataUpdater implemented as Python threads
  - Loading of caches from PyOCF Volumes (fix bugs in OCF)
  - Make sure it works multi-threaded for more sophisticated tests
