Make error reporting of funcsim more verbose and clear about mdsp HOT 6 CLOSED

Over to the maintaner

I suggest for macros' names to use CAPITAL letters.
E.g.:
  ASSERT(x == True, "Message if not valid!");
  ERROR("Some text here");
  WARNING("You sir, I want to take you to a...");

Currently message printing is being made more object-oriented. 
After this work is done we may use wrapping the methods in #define's if this 
would seem reasonable. 

Anyway Grisha please don't allow commits with coding style violations

This task is nont about macroes, its about new class log and its methods 
log::critical() and logg:warning(). No macroes were introduced so far as far as 
I can find. Please point me to the place where the recent code commits violate 
coding styles.

The task was partly committed. Also we dropped the idea to support this feature.
