sc_prim_channel::wait (was Re: nb_peek)

John,

agreed on the nb_peek issue.
For sc_prim_channel, see below.

Note, that it should/could be (no members accessed inside):

void wait( ... ) const // <- method itself should be const

This way, primitive channels could call wait inside but const member
functions. Strictly speaking, this affects sc_module::wait as well
although processes in const functions are quite rare, I suppose.

Of course, inside tlm_fifo<T>::peek a direct call to sc_core::wait(...)
would have been sufficient instead of the const_cast.
