Move HexStr and HexDigit functions from util to crypto. The crypto library does not actually use these functions, but the consensus library does. The consensus and util libraries not allowed to depend on each other, but are allowed to depend on the cryto library, so the crypto library is a reasonable put these. The consensus library uses HexStr and HexDigit in script.cpp, transaction.cpp, and uint256.cpp. The util library does not use HexStr but does use HexDigit in strencodings.cpp to parse integers.
