sun4v: add incomplete implementation of the CD-specific READ_DISCINFO and READ_TRACKINFO - probably needs some more work though...

sun4v: fix vdsk so an iso image exported by the ldom virtual disk service is correctly detected as a cd device + some whitespace fixes

extract capacity variable to make VDSK_DEBUG enabled code build.

sun4v/vdsk: add handling of SCSI_REPORT_LUNS

fix typos in comments and log messages, mainly in establish(ed).

sun4v: vdsk - restart the ldc state machine when the ldc endpoint resets the link or a DATA/NACK/DRING_DATA message is received. These changes make the driver more robust. In a ldom with Solaris 11.4 SRU30 as primary domain (T5 host system) frequent resets and NACK messages are observed.

branches: 1.6.2;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).
