changelog: handle writepending in the transaction
The 'delayupdate' method now takes a transaction object and registers its
'_writepending' method for execution in 'transaction.writepending()'. The hook can then
use 'transaction.writepending()' directly.
At some point this will allow the addition of other file creation
during writepending.
