The Split <-> Account and Split <-> Transaction relationships are now
treated as properties of the Split. In terms of the BeginEdit/CommitEdit
block, Splits are subordinate to Transactions. There is no public
BeginEdit/CommitEdit block for Splits; changes to Splits should be wrapped
in their Transaction's Edit-block.
In the case of the Split <-> Account relationship, the call to
xaccSplitSetAccount() will be immediately visible from
xaccSplitGetAccount(), but the Account does not learn about the
Split until and if the edit is committed.
In the case of the Split <-> Transaction relationship, calling
xaccSplitSetParent() will immediately add the Split to the
Transactions split list. This is because the Split's Transaction
owns the reference to the Split. However, see the Transaction.c
patch for how to distinguish pre-edit state from in-edit state.
In both cases, events are not generated until the edits are committed.
Most of this new logic is in an engine-private helper xaccSplitCommitEdit(),
which is called from xaccTransCommitEdit().
Incidental:
Increased error-checking in xaccSplitSetValue().
Internalize a Transaction Begin/Commit edit-block in every setter func.
