The on disk log format definitions for the icreate log item are
intertwined with the kernel-only in-memory log item definitions.
Separate the log format definitions out into their own header file
so they can easily be shared with userspace.

Introduce the inode create log item type for logical inode create logging.
Instead of logging the changes in buffers, pass the range to be
initialised through the log by a new transaction type. This reduces
the amount of log space required to record initialisation during
allocation from about 128 bytes per inode to a small fixed amount
per inode extent to be initialised.
This requires a new log item type to track it through the log
and the AIL. This is a relatively simple item - most callbacks are
noops as this item has the same life cycle as the transaction.
