xfs: introduce xlog_write_full()

Introduce an optimised version of xlog_write() that is used when the
entire write will fit in a single iclog. This greatly simplifies the
implementation of writing a log vector chain into an iclog, and sets
the ground work for a much more understandable xlog_write()
implementation.

This incorporates some factoring and simplifications proposed by
Christoph Hellwig.
