This addresses some header check warnings. DRM headers which include
"drm.h" have been excluded, as they indirectly include types.h.

Commit 9e4f5e29 ("FC Pass Thru support") exported a number of header files
in include/scsi to user space, but didn't change the uX types to the
userspace-compatible __uX types. Without that you'll get compile errors
when including them - E.G.:

include/scsi/scsi.h:145: error: expected specifier-qualifier-list before `u8'

This patch adds scsi netlink recieve and event support for transport
and scsi LLDD's. It is a reimplementation of the patch posted last
week by David Somayajulu.
http://marc.info/?l=linux-scsi&m=121745486221819&w=2

There are a few things done differently:

- Transport support is included

- Event delivery is included

- The vendor message is now its own unique message type, considered
part of the generic "SCSI Transport".

- LLDD entry points are now registered rather than included in the
scsi_host_template.

Background: When I started to implement the event handler via template,
I had to either: muck up scsi_add_host and scsi_remove_host; or have
the event handler search all possible shosts. Neither was acceptable.
Moving to a registration solves this, and also limits the scope of
the changes to something that could be backported to a distro without
breaking an already-released-distro kabi. However, I admit it isn't
as elegant, as the passing of the LLDD host template in the
registration and the complexity around dynamic add/remove shows.

- The receive path was augmented to require a unique identifier for
the LLDD before the message was allowed to be handed off to the
driver. Given how quickly very fatal errors occur if there's msg
mismatches (which I saw in testing my own tools :), I believe this
to be a very good thing. The id plays off the vendor id scheme already
introduced for the vendor unique event messages used by FC.
Additionally, the id use as the basis of the registration/deregistration.

- Send assist functions, for both the transport and LLDDs are included.

During discussions with Mike Christie, I became convinced that we needed
a larger vendor id. This patch extends the id from 32 to 64 bits.

This applies on top of the prior patches that add SCSI transport events
via netlink.

This patch formally adds support for the posting of FC events via netlink.
It is a followup to the original RFC at:
http://marc.theaimsgroup.com/?l=linux-scsi&m=114530667923464&w=2
and the initial posting at:
http://marc.theaimsgroup.com/?l=linux-scsi&m=115507374832500&w=2

The patch has been updated to optimize the send path, per the discussions
in the initial posting.

Per discussions at the Storage Summit and at OLS, we are to use netlink for
async events from transports. Also per discussions, to avoid a netlink
protocol per transport, I've create a single NETLINK_SCSITRANSPORT protocol,
which can then be used by all transports.

This patch:
- Creates new files scsi_netlink.c and scsi_netlink.h, which contains the
single and shared definitions for the SCSI Transport. It is tied into the
base SCSI subsystem intialization.
Contains a single interface routine, scsi_send_transport_event(), for a
transport to send an event (via multicast to a protocol specific group).
- Creates a new scsi_netlink_fc.h file, which contains the FC netlink event
messages
- Adds 3 new routines to the fc transport:
fc_get_event_number() - to get a FC event #
fc_host_post_event() - to send a simple FC event (32 bits of data)
fc_host_post_vendor_event() - to send a Vendor unique event, with
arbitrary amounts of data.

Note: the separation of event number allows for a LLD to send a standard
event, followed by vendor-specific data for the event.

Note: This patch assumes 2 prior fc transport patches have been installed:
http://marc.theaimsgroup.com/?l=linux-scsi&m=115555807316329&w=2
http://marc.theaimsgroup.com/?l=linux-scsi&m=115581614930261&w=2

Sorry - next time I'll do something like making these individual
patches of the same posting when I know they'll be posted closely
together.
