\section bench_libc A few of libc functions.

Avr-gcc version is 4.2.3

The size of function is given in view of all picked up functions. By default
Avr-libc is compiled with \c -mcall-prologues option. In brackets the size
without taking into account modules of a prologue and an epilogue is
resulted. Both of the size can coincide, if function does not cause a
prologue/epilogue.
