CheckPackage()

bool CheckPackage	(	const Package &	txns,
		PackageValidationState &	state
	)

Context-free package policy checks:

1. The number of transactions cannot exceed MAX_PACKAGE_COUNT.
2. The total weight cannot exceed MAX_PACKAGE_WEIGHT.
3. If any dependencies exist between transactions, parents must appear before children.
4. Transactions cannot conflict, i.e., spend the same inputs.
