Move most of the contents of opt_compat.h to opt_global.h.

opt_compat.h is mentioned in nearly 180 files. In-progress network
driver compabibility improvements may add over 100 more so this is
closer to "just about everywhere" than "only some files" per the
guidance in sys/conf/options.

Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of
sys/compat/linux/*.c. A fake _COMPAT_LINUX option ensure opt_compat.h
is created on all architectures.

Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the
set of compiled files.

Update for changes in driver name and API. The ioctl interface
is largely unchanged and could use additional refinement. It
would be nice to be able to fetch the status of all elements in
a single ioctl call and to have the ioctls that return variable
length data allow you to query the necessary allocation size
by passing in a zero length buffer.

Split the enc driver into a generic driver file and one file
each for the SES and SAF-TE personalities.

sys/cam/scsi/scsi_ses.h:
o Retain this header, but use it to only hold structures derived
from the T10 SES spec. The driver interface can be found in
scsi_enc.h.
o Add definitions for most SES pages.

sys/cam/scsi/scsi_enc.c
sys/cam/scsi/scsi_enc.h
o Use a function vector table to allow interaction between the
generic and protocol specific portions of this driver.
o Provide a generic mechanism allowing personalities to define a
finite state machine that is executed from a daemon thread context.
o Track CAM device arrival events and pass these on to personalities
that have registered an interest in them. These notifications are
used to trigger physical path updates in the CAM EDT.

sys/cam/scsi/scsi_enc_safte.c:
The SAF-TE personality. This module is largely untouched by this
update. To achieve the same level of support as we have for SES,
it will need to define an FSM and code to determine the physical
paths of elements within the enclosure.

sys/cam/scsi/scsi_enc_ses.c:
o Implement a state machine to fetch configuration, status, element
descriptors, and additional element status.
o Build a "element map" that indexes into the config and status
data retrieved from a SES device. Use this to simplify our
responses to ioctls.
o Add support for using SAS domain/phy WWN data to determine the
physical path (ence@<enc WWN>/type@<elm type>/slot@<slot #>)
of an element. Stubs are in place for FC, but both FC and SPI
will need additional work in order to be supported.
