trivia: added TOSTR() util

The `TOSTR` helper macro for stringization via snprintf-functions
to dynamically allocated buffer is introduced.

It's name referred to existing stringization functions, which are write
to dynamically allocated buffer and are named `xxx_str()` in most cases.

The purpose of the new macro and this PR are:
- to speedup and to simplify the writing of new `xxx_str()` functions
  and to allow more optimal use of static buffer space for them.
- to make unified implementation for them with painstaking error handling.
- to make possible dynamically stringization, when `xxx_str()` function
  is absent. `TOSTR(xxx_snprint, xxx)` macro may be used explicitly.
  In particular, this may be very helpful for testing and debugging.
- to encourage the use of snprint functions as a common way for
  stringization.
