Merge patch series "Import "string" I/O functions from Linux"

To quote the author:

This series imports generic versions of ioread_rep/iowrite_rep and
reads/writes from Linux. Some cleanup is done to make sure that all
platforms have proper defines for implemented functions and there are no
redefinitions.
