sys: Remove $FreeBSD$: one-line .c pattern

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

Add the mfi(4) ioctl support to mrsas(4)

The hardware supported by mfi(4) and mrsas(4) use the same dcmd's.
mfiutil(8) in theory could run on controlled attached to mrsas(4).
It can't since mrsas(4) doesn't have support for the FreeBSD mfi(4)
ioctl. Porting the ioctl from mfi(4) to mrsas(4) would be the first
step in making mrsasutil(8) which is an additional name for mfiutil(8)
but opens /dev/mrsasX instead of /dev/mfiX

This is a feature provided to run 32-bit linux binaries on FreeBSD 64bit
machine, for which 32bit compatibilty code has been added.
As in linux there is only one device entry that is used to fire IOCTL commands,
a new device entry megaraid_sas_ioctl_node is added for solely this
purpose.

From one dev node i.e mrgaraid_sa_ioctl_node we have to find out the
controller instance in case of multicontroller, for which one management info
structure has been added.

Add mrsas(4) driver from LSI official support of newer MegaRAID SAS
cards. LSI has been maintaining this driver outside of the FreeBSD
tree. It overlaps support of ThunderBolt and Invader cards that mfi(4)
supports. By default mfi(4) will attach to cards. If the tunable:
hw.mfi.mrsas_enable=1
is set then mfi(4) will not probe and attach to these newer cards and
allow mrsas(4) to attach. So by default this driver will not effect
a FreeBSD system unless mfi(4) is removed from the kernel or the
tunable is enabled.

mrsas(4) attaches disks to the CAM layer so it depends on CAM and devices
show up as /dev/daX. mfiutil(8) does not work with mrsas. The FreeBSD
version of MegaCli and StorCli from LSI do work with mrsas. It appears
that StorCli only works with mrsas. MegaCli appears to work with mfi(4)
and mrsas(4).

It would be good to add mfiutil(4) support to mrsas, emulations modes,
kernel logging, device aliases to ease the transition between mfi(4)
and mrsas(4).

Style issues should be resolved by LSI when they get committers approved.
The plan is get this driver in FreeBSD 9.3 to improve HW support.

Thanks to LSI for developing, testing and working with FreeBSD to
make this driver co-exist in FreeBSD. This improves the overall
support of MegaRAID SAS.
