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.
