Move the CLI related functions main() and cli_usage() to cli_classic.c

And rename them accordingly. For now, main() just calls cli_classic(),
but alternative frontends can be switched in main().
Annotate remaining help texts with CLI dependency inside flashrom.c with
a FIXME comment.

Now people can go and create different frontends and be happy. Please
note that any other frontend will have to sort of duplicate the probing
code in cli_classic.c. Refactoring that part of the code is possible,
but not easy because we still want to print instructive help messages
for users.

Corresponding to flashrom svn r833.
