092ac26ea2 Fix undefined behavior with pointer addition in channeltls.c
In C, it's a bad idea to do this:

   char *cp = array;
   char *end = array + array_len;

   /* .... */

   if (cp + 3 >= end) { /* out of bounds */ }

because cp+3 might be more than one off the end of the array, and
you are only allowed to construct pointers to the array elements,
and to an element one past the end.  Instead you have to say

   if (cp - array + 3 >= array_len) { /* ... */ }

or something like that.

This patch fixes two of these: one in process_versions_cell
introduced in 0.2.0.10-alpha, and one in process_certs_cell
introduced in 0.2.3.6-alpha.  These are both tracked under bug
10363. "bobnomnom" found and reported both. See also 10313.

In our code, this is likely to be a problem as we used it only if we
get a nasty allocator that makes allocations end close to (void*)-1.
But it's best not to have to worry about such things at all, so
let's just fix all of these we can find.

c230ff4ca9 Look at all of a RESOLVED cell; not just the first answer.
Also, stop accepting the old kind of RESOLVED cells with no TTL
fields; they haven't been sent since 0.1.1.6-alpha.

This patch won't work without the fix to #10468 -- it will break
DNSPorts unless they set the proper ipv4/6 flags on entry_connection_t.

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.
