xpt_bus_register and xpt_bus_deregister returns a hybrid error that's
neither a cam_status, nor an errno, but a mix of both. Update
xpt_bus_register and xpt_bus_deregister to return an errno. The vast
majority of current users compare against zero, which can also be
spelled CAM_SUCCESS. Nobody uses CAM_FAILURE, so remove that symbol
to prevent comfusion (nothing returns it either).
Where the return value is saved, ensure that the variable 'error' is
used to store an errno and 'status' is used to store a cam_status where
it makes the code clearer (usually just in functions that already mix
and match). Where the return value isn't used at all, avoid storing it
at all.

pqisrc_is_firmware_feature_enabled shouldn't be declared inline in a
header, and then static inline in the .c function. Remove this stray
declartion from the header. gcc6 complains, but clang does not.

It includes:
1)Newly added TMF feature.
2)Added newly Huawei & Inspur PCI ID's
3)Fixed smartpqi driver hangs in Z-Pool while running on FreeBSD12.1
4)Fixed flooding dmesg in kernel while the controller is offline during in ioctls.
5)Avoided unnecessary host memory allocation for rcb sg buffers.
6)Fixed race conditions while accessing internal rcb structure.
7)Fixed where Logical volumes exposing two different names to the OS it's due to the system memory is overwritten with DMA stale data.
8)Fixed dynamically unloading a smartpqi driver.
9)Added device_shutdown callback instead of deprecated shutdown_final kernel event in smartpqi driver.
10)Fixed where Os is crashed during physical drive hot removal during heavy IO.
11)Fixed OS crash during controller lockup/offline during heavy IO.
12)Fixed coverity issues in smartpqi driver
13)Fixed system crash while creating and deleting logical volume in a continuous loop.
14)Fixed where the volume size is not exposing to OS when it expands.

In PR 243056 a user reports some spam from smartpqi(4). In particular,
the driver warns about an unrecognized PQI_CONF_TABLE_SECTION_SOFT_RESET
section (not yet defined in the driver, but handled in Linux), but this
doesn't cause any problems. The Linux driver also does not warn about
unrecognized sections.
Also do not log a warning when a device is added, since this is routine.
Lower severity to DISC, to match pqisrc_remove_device().

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"
in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header
pollution substantially.
EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c
files into appropriate headers (e.g., sys/proc.h, powernv/opal.h).
As a side effect of reduced header pollution, many .c files and headers no
longer contain needed definitions. The remainder of the patch addresses
adding appropriate includes to fix those files.
LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by
sys/mutex.h since r326106 (but silently protected by header pollution prior
to this change).
No functional change (intended). Of course, any out of tree modules that
relied on header pollution for sys/eventhandler.h, sys/lock.h, or
sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.
CAM_RESRC_UNAVAIL instead of CAM_REQUEUE_REQ. This makes CAM delay a bit
before retrying, so that the retries actually get a chance to succeed.

- Microsemi SCSI driver for PQI controllers.
- Found on newer model HP servers.
- Restrict to AMD64 only as per developer request.
The driver provides support for the new generation of PQI controllers
from Microsemi. This driver is the first SCSI driver to implement the PQI
queuing model and it will replace the aacraid driver for Adaptec Series 9
controllers. HARDWARE Controllers supported by the driver include:
HPE Gen10 Smart Array Controller Family
OEM Controllers based on the Microsemi Chipset.
