The reason to do so is because these functions haven't been used in years so
since 0.2.4, every callsite is NOP.
In future commits, we'll remove the round robin circuit policy which is mostly
validated within those function.
This simplifies the code greatly and remove dead code for which we never had a
configure option in the first place nor an easy way to use them in production.

It is rename to something more meaningful that explains what it does exactly
which is sets the EWMA options (currently only one exists). The new name is
cmux_ewma_set_options().
Also, remove a public function from circuitmux_ewma.h that is only used in the
C file. Make it static inline as well.

To achieve this, a default value for the CircuitPriorityHalflife option was
needed. We still look in the options and then the consensus but in case no
value can be found, the default CircuitPriorityHalflifeMsec=30000 is used. It
it the value we've been using since 0.2.4.4-alpha.
This means that EWMA, our only policy, can not be disabled anymore fallbacking
to the round robin algorithm. Unneeded code to control that is removed in this
commit.

We had this safeguard around dos_init() but not when the consensus changes
which can modify consensus parameters and possibly enable the DoS mitigation
even if tor wasn't a public relay.

Explicitly inform the operator of the rejected relay to set a valid email

We don't expect this to come up very much, but we may as well make
sure that the value isn't predictable (as we do for the other
addresses) in case the issue ever comes up.
Spotted by teor.
This patch lowers the log-level from warning to info in the cases where
we are going to attempt another method as entropy source to hopefully
make the user feel less concerned.
