Subject: [PATCH 44/79] class: rename "devices" to "class_devices" in internal class structure

This renames the struct class "devices" field to be "class_devices" to
make things easier when struct bus_type and struct class merge in the
future.  It also makes grepping for fields easier as well.

Based on an idea from Kay.
