Functions
bool	CheckPackage (const Package &txns, PackageValidationState &state)
	Context-free package policy checks:
bool	IsChildWithParents (const Package &package)
	Context-free check that a package is exactly one child and its parents; not all parents need to be present, but the package must not contain any transactions that are not the child's parents.
bool	IsChildWithParentsTree (const Package &package)
	Context-free check that a package IsChildWithParents() and none of the parents depend on each other (the package is a "tree").

Function Documentation

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 virtual size cannot exceed MAX_PACKAGE_SIZE.
3. If any dependencies exist between transactions, parents must appear before children.
4. Transactions cannot conflict, i.e., spend the same inputs.

Context-free check that a package is exactly one child and its parents; not all parents need to be present, but the package must not contain any transactions that are not the child's parents.

It is expected to be sorted, which means the last transaction must be the child.
