Removed any instances of the_* and this_* to variable names that are more
meaningful and tell us what they actually are.

Instead of filling up tables with default handlers call the default
handler in the only caller.

IMHO the whole state handlers concept is not very suitable for the
isci request.  For example there is a single real instance of the
start handler, and we'd be much better off just having a check for
the right state in the only caller, than all this mess.  It's
quite similar for the abort handler as well.

Even the actual state machine has a lot of states that are rather
pointless.  The initial and constructed states are not needed at all
as the request is not reachable for calls before it's fully set up and
started.  And the abort state should be replaced with an abort actions
and a state transition to the completed state.

Merge struct sci_base_request into scic_sds_request, and also factor the two
types of state machine handlers into one function.  While we're at it also
remove lots of duplicate incorrect kerneldoc comments for the state machine
handlers.

Remove duplicated license and header file includes that were leftover
from commit 4c1db2d0 "isci: consolidate core" (in the isci.git historical
branch).

Support for the up to 2x4-port 6Gb/s SAS controllers embedded in the
chipset.

This is a snapshot of the first publicly available version of the driver,
commit 4c1db2d0 in the 'historical' branch.
