734ba5cb0a Use smaller zlib objects when under memory pressure 
We add a compression level argument to tor_zlib_new, and use it to
determine how much memory to allocate for the zlib object.  We use the
existing level by default, but shift to smaller levels for small
requests when we have been over 3/4 of our memory usage in the past
half-hour.

Closes ticket 11791.

1196ed7cc4 Fix relay_command_to_string(); solve 12700. 
Two bugs here:
  1) We didn't add EXTEND2/EXTENDED2 to relay_command_to_string().

  2) relay_command_to_string() didn't log the value of unrecognized
     commands.

Both fixed here.

cells in several ways.  Check to see whether any of the marked circuit
IDs have somehow been marked longer than the channel has existed.

d9564d5285 Use uint32 !=, not tor_memneq, for relay cell integrity checking 
tor_memeq has started to show up on profiles, and this is one of the
most frequent callers of that function, appearing as it does on every
cell handled for entry or exit.

59f9097d5c introduced tor_memneq here;
it went into Tor 0.2.1.31.  Fixes part of 12169.

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.

1a74360c2d Test code for implementation of faster circuit_unlink_all_from_channel 
This contains the obvious implementation using the circuitmux data
structure.  It also runs the old (slow) algorithm and compares
the results of the two to make sure that they're the same.

Needs review and testing.

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.

9a07ec751f Refactor OOM-handling functions for more testability
