Ricardo M. Correia fe78c9ae8b Don't overflow signed ints in CBigNum::setint64(). 
CBigNum::setint64() does 'n <<= 8', where n is of type "long long".

This leads to shifting onto and past the sign bit, which is undefined
behavior in C++11 and can cause problems in the future.

Ricardo M. Correia 4843b55fd1 Make CNetAddr::GetHash() return an unsigned val. 
This prevents an undefined operation in main.cpp, when shifting the hash value
left by 32 bits.
Shifting a signed int left into the sign bit is undefined in C++11.
