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.

Refactor disk disconnection and geom destruction handling sequences. Do not close/destroy opened consumer directly in case of disconnect. Instead keep it existing until it will be closed in regular way in response to upstream provider destruction. Delay geom destruction in the same way. Previous implementation could destroy consumers still having active requests and worked only because of global workaround made on GEOM level.

- Add md_provsize field to metadata, which will help with shared-last-sector problem. After this change, even if there is more than one provider with the same last sector, the proper one will be chosen based on its size. It still doesn't fix the 'c' partition problem (when da0s1 can be confused with da0s1c) and situation when 'a' partition starts at offset 0 (then da0s1a can be confused with da0s1 and da0s1c). One can use '-h' option there, when creating device or avoid sharing last sector. Actually, when providers share the same last sector and their size is equal, they provide exactly the same data, so the name (da0s1, da0s1a, da0s1c) isn't important at all. - Provide backward compatibility. - Update copyright's year.

- Introduce option for hardcoding providers' names into metadata. It allows to fix problems when last provider's sector is shared between few providers. - Bump version number for CONCAT and STRIPE and add code for backward compatibility. - Do not bump version number of MIRROR, as it wasn't officially introduced yet. Even if someone started to play with it, there is no big deal, because wrong MD5 sum of metadata will deny those providers. - Update manual pages. - Add version history to g_(stripe|concat).h files.
