nb_peek

The usual behavior of method

tlm_fifo<T>::nb_peek( T &t , int n ) const

is to return a reference to the item at location n, where 0 <= n <
size()-1

However, the code includes a hack to accept n == -1, and have it
equivalent to n == size()-1, i.e. peek the oldest item in the FIFO.
Strangely, nb_poke does not have the equivalent special case.

Do we want to document this special case of nb_peek in the LRM, in which
case, should we add the same special case n == -1 to nb_poke?
