Eric Lombrozo 05df3fc68d Removed AcceptToMemoryPool method from CTransaction. This method belongs to the mempool instance.
Removed AreInputsStandard from CTransaction, made it a regular function in main.
Moved CTransaction::GetOutputFor to CCoinsViewCache.

Moved GetLegacySigOpCount and GetP2SHSigOpCount out of CTransaction into regular functions in main.

Moved GetValueIn and HaveInputs from CTransaction into CCoinsViewCache.

Moved AllowFree, ClientCheckInputs, CheckInputs, UpdateCoins, and CheckTransaction out of CTransaction and into main.

Moved IsStandard and IsFinal out of CTransaction and put them in main as IsStandardTx and IsFinalTx. Moved GetValueOut out of CTransaction into main. Moved CTxIn, CTxOut, and CTransaction into core.

Added minimum fee parameter to CTxOut::IsDust() temporarily until CTransaction is moved to core.h so that CTxOut needn't know about CTransaction.
