This causes CCoinsViewCache(CCoinsViewCache) to fail at compile-time rather than copy an existing cache (most likely the caller intends to sub-cache it)

It also makes ConnectBlock's fJustCheck work correctly for the genesis block, just in case it gets in there somehow.

Make CCoinsViewCache's copy constructor private

It is easily confused with CCoinsViewCache(CCoinsView*), which creates a sub-cache, but instead of creating a sub-cache, the copy constructor would copy the original and use that original's base, defeating the intended isolation.
