Now that the core/lldd remote_device data structures are nominally unified
merge the corresponding sources into the top-level directory.  Also move the
remote_node_context infrastructure which has no analog at the lldd level.

Delete some macros that are longer to type than the open coded operation
that they perform.

scic_sds_phy_get_base_state_machine
scic_sds_phy_get_starting_substate_machine
scic_sds_port_get_base_state_machine
scic_sds_port_get_ready_substate_machine
scic_sds_remote_device_get_base_state_machine
scic_sds_remote_device_get_ready_substate_machine
scic_sds_remote_node_context_set_remote_node_index
scic_sds_controller_get_base_state_machine

Also performs some collateral cleanups like killing casts that assume
structure member ordering, and consolidating a lot of duplicated default
handler code (the primary callers of the *_get_base_state_machine macros) via
a helper.

c99 the struct initializers (scic_sds_remote_device_state_handler_table[]):
	1/ allows grep to consistently show method name associations.  The
	   naming is mostly consistent (except when it isn't) so this guarantees
	   coverage of present and future exception cases.
	2/ let's the compiler guarantee that the state table array entry
	   correlates with an actual state name and detect accidental reordering or
	   deletion of states.
	3/ allows default handler's to be identified easily
