adds a warning if you put explicit ports in any of the options
{Socks,Dir}Policy or AuthDir{Reject,Invalid,BadDir,BadExit}.  It
also adjusts the manpage to say that ports are ignored.

833d027778 Monotonize the OOM-killer data timers 
In a couple of places, to implement the OOM-circuit-killer defense
against sniper attacks, we have counters to remember the age of
cells or data chunks.  These timers were based on wall clock time,
which can move backwards, thus giving roll-over results for our age
calculation.  This commit creates a low-budget monotonic time, based
on ratcheting gettimeofday(), so that even in the event of a time
rollback, we don't do anything _really_ stupid.

A future version of Tor should update this function to do something
even less stupid here, like employ clock_gettime() or its kin.

d3fb846d8c Split crypto_global_init() into pre/post config 
It's increasingly apparent that we want to make sure we initialize our
PRNG nice and early, or else OpenSSL will do it for us.  (OpenSSL
doesn't do _too_ bad a job, but it's nice to do it ourselves.)

We'll also need this for making sure we initialize the siphash key
before we do any hashes.

0e97c8e23e Siphash-2-4 is now our hash in nearly all cases. 
I've made an exception for cases where I'm sure that users can't
influence the inputs.  This is likely to cause a slowdown somewhere,
but it's safer to siphash everything and *then* look for cases to
optimize.

This patch doesn't actually get us any _benefit_ from siphash yet,
since we don't really randomize the key at any point.
