- convert rf_printf_mutex to a kmutex - convert rf_rad_lock and the per-raid "cv" to per-raid kmutex/and real cv - use rf_mutex_init() in places, and move it with the similar definitions

/* $NetBSD: rf_driver.h,v 1.19 2011/04/30 01:44:36 mrg Exp $ */
RAIDframe, version 1.1, from the Parallel Data Laboratory at Carnegie Mellon University. Full RAID implementation, including levels 0, 1, 4, 5, 6, parity logging, and a few other goodies. Ported to NetBSD by Greg Oster.

Step 2 of the disentanglement. We now look to <dev/raidframe/*> for the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h, rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places. Believe it or not, when this is all done, things will be cleaner. No functional changes to RAIDframe.

Get recent changes into the tree: - make component_label variables more consistent (==> clabel) - re-work incorrect component configuration code - re-work disk configuration code - cleanup initial configuration of raidPtr info - add auto-detection of components and RAID sets (Disabled, for now) - allow / on RAID sets (Disabled, for now) - rename "config_disk_queue" to "rf_ConfigureDiskQueue" and properly prototype in rf_diskqueue.h - protect some headers with #if _KERNEL (XXX this needs to be fixed properly) and cleanup header formatting. - expand the component labels (yes, they should be backward/forward compatible) - other bits and pieces (some function names are still bogus, and will get changed soon)

On an idea from Thor (tls@), do not fail a component if doing so would render the RAID set completely dead. Instead, we retry the IO a maximum of RF_RETRY_THRESHOLD times (currently '5'), and then just return an IO error if the IO fails. This should reduce the damage caused by having multiple disks appear to fail when the culprit is really something else (power, controllers, etc.)
