Add c++14 delete operators and rename call counters to have more accurate name.

In c++14 are presented new delete, operators which must be hooked to preserve correct functionality.

Also rename counters which count calls of hooked functions. Malloc counter and free counter count more than free() or malloc() so to make sure nobody will mistaken function of counters, the new name is used.
Add initial files for debug functionality. Also add them into autotools files.
