MFC r265054: Reduce number of opens by REOM RAID during provider taste.
Instead opening/closing provider by each of metadata classes, do it only once in core code. Since for SCSI disks open/close means sending some SCSI commands to the device, this change reduces taste time.

MFC Alexander Motin's GEOM direct dispatch work:
r256603: Introduce new function devstat_end_transaction_bio_bt(), adding new argument to specify present time. Use this function to move binuptime() out of lock, substantially reducing lock congestion when slow timecounter is used.
r256606: Move g_io_deliver() out of the lock, as required for direct dispatch. Move g_destroy_bio() out too to reduce lock scope even more.
r256607: Fix passing uninitialized bio_resid argument to g_trace().
r256610: Add unmapped I/O support to GEOM RAID.
r256830: Restore BIO_UNMAPPED and BIO_TRANSIENT_MAPPING in biodonne() when unmapping temporary mapped buffer. That fixes double unmap if biodone() called twice for the same BIO (but with different done methods).
r256880: Merge GEOM direct dispatch changes from the projects/camlock branch.
When safety requirements are met, it allows to avoid passing I/O requests to GEOM g_up/g_down thread, executing them directly in the caller context. That allows to avoid CPU bottlenecks in g_up/g_down threads, plus avoid several context switches per I/O.
r259247: Fix bug introduced at r256607. We have to recalculate bp_resid here since sizes of original and completed requests may differ due to end of media.
Testing of the stable/10 merge was done by Netflix, but all of the credit goes to Alexander and iX Systems.

Add legacy support to geom raid to create a /dev/arX device for support of upgrading older machines using ataraid(4) to newer releases.
This optional parameter is controlled via kern.geom.raid.legacy_aliases and will create a /dev/ar0 device that will point at /dev/raid/r0 for example.
Tested on Dell SC 1425 DDF-1 format software raid controllers installing from stable/7 and upgrading to stable/9 without having to adjust /etc/fstab

Add basic support for Intel Rapid Recover Technology (Intel RRT). It is alike to RAID1, but with dedicating master and recovery disks and providing manual control over synchronization. It allows to use recovery disk as snapshot of the master disk from the time of the last sync.
This implementation is not functionaly complete comparing to Windows, but it is better then silent conversion to RAID1 on first boot.

Add basic BIO_DELETE support to GEOM RAID class for all RAID levels.
If at least one subdisk in the volume supports it, BIO_DELETE requests will be propagated down. Unfortunatelly, for RAID levels with redundancy unmapped blocks will be mapped back during first rebuild/resync process.

Make GEOM RAID more aggressive in marking volumes as clean on shutdown and move that action from shutdown_pre_sync to shutdown_post_sync stage to avoid extra flapping.
ZFS tends to not close devices on shutdown, that doesn't allow GEOM RAID to shutdown gracefully. To handle that, mark volume as clean just when shutdown time comes and there are no active writes.

MFgraid/head: Add new RAID GEOM class, that is going to replace ataraid(4) in supporting various BIOS-based software RAIDs. Unlike ataraid(4) this implementation does not depend on legacy ata(4) subsystem and can be used with any disk drivers, including new CAM-based ones (ahci(4), siis(4), mvs(4), ata(4) with `options ATA_CAM`). To make code more readable and extensible, this implementation follows modular design, including core part and two sets of modules, implementing support for different metadata formats and RAID levels.
Support for such popular metadata formats is now implemented: Intel, JMicron, NVIDIA, Promise (also used by AMD/ATI) and SiliconImage.
Such RAID levels are now supported: RAID0, RAID1, RAID1E, RAID10, SINGLE, CONCAT.
For any all of these RAID levels and metadata formats this class supports full cycle of volume operations: reading, writing, creation, deletion, disk removal and insertion, rebuilding, dirty shutdown detection and resynchronization, bad sector recovery, faulty disks tracking, hot-spare disks. For Intel and Promise formats there is support multiple volumes per disk set.
Look graid(8) manual page for additional details.
