1c4aab926e Retain only the most recent time samples 
Remembering all time samples makes nTimeOffset slow to respond to
system clock corrections.  For instance, I start my node with a system
clock that's 30 minutes slow and run it for a few days.  During that
time, I accumulate 10,000 offset samples with a median of 1800
seconds.  Now I correct my system clock.  Without this change, my node
must collect another 10,000 samples before nTimeOffset is correct
again.  With this change, I must only accumulate 100 samples to
correct the offset.

Storing unlimited time samples also allows an attacker with many IP
addresses (ex, a large botnet) to perform a memory exhaustion attack
against Bitcoin nodes.  The attacker sends a version message from each
IP to his target, consuming more of the target's memory each time.
Time samples are small, so this attack might be impractical under the
old code, but it's impossible with the new code.

5e1ddc4210 Only log time samples in debug mode 
The full list of time samples is rarely useful outside of debugging.
The node's time offset, however is useful for discovering local clock
drift, so it's displayed in all logging modes.

94f778bdeb Implement an mlock()'d string class for storing passphrases 
SecureString is identical to std::string except with secure_allocator
substituting for std::allocator. This makes casting between them
impossible, so converting between the two at API boundaries requires
calling ::c_str() for now.
