Litecoin: Protocol and default settings 
0) Adjust BIP30 enforcement values

1) Reduce amount that peers can adjust our time to eliminate an attack vector. Thanks to
coblee for this fix.

2) Zeitgeist2 patch - thanks to Lolcust and ArtForz. This fixes an issue where a
51% attack can change difficulty at will. Go back the full period unless it's the
first retarget after genesis.

3) Avoid overflow in CalculateNextWorkRequired(). Thanks to pooler for the overflow fix.

4) Zeitgeist2 bool fshift bnNew.bits(). Thanks to romanornr for this path.

5) SegWit ContextualCheckBlockHeader adjustment and extra coverage.

6) Reject peer proto version below 70002. Thanks to wtogami for this patch.

7) Send final alert message to nodes warning about removal of the alert system. Thanks to coblee for this patch.

8) Adjust default settings for Litecoin.

Add unit tests for next difficulty calculations 
Split GetNextWorkRequired() into two functions to allow the difficulty calculations to
be tested without requiring a full blockchain.
Add unit tests to cover basic difficulty calculation, plus each of the min/max actual
time, and maximum difficulty target conditions.

ad49c256c3 Split up util.cpp/h 
Split up util.cpp/h into:

- string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach)
- money utilities (parsesmoney, formatmoney)
- time utilities (gettime*, sleep, format date):
- and the rest (logging, argument parsing, config file parsing)

The latter is basically the environment and OS handling,
and is stripped of all utility functions, so we may want to
rename it to something else than util.cpp/h for clarity (Matt suggested
osinterface).

Breaks dependency of sha256.cpp on all the things pulled in by util.
