MFC r294557:

hyperv/stor: Verify returned inquiry data before further dispatching

Windows 10 and Window 2016 will return all zero inquiry data for
non-existing slots. If we dispatched them, then a lot of useless
(0 sized) disks would be created. So we verify the returned inquiry
data (valid type, non-empty vendor/product/revision etc.), before
further dispatching.

Minor white space cleanup and wording fix.

Make some unwise casts. On i386 these casts wind up being safe. Rather
than disturb the API, go with these casts to shut gcc up.

Import Hyper-V paravirtualized drivers from projects/hyperv
branch into head.

Approved by: re@ (hrs)
Obtained from: Microsoft, NetApp, and Citrix.

Microsoft have changed their policy on how the hyper-v code will
be pulled into FreeBSD. From now, FreeBSD will be considered the
upstream repo.

First step: move the drivers away from the contrib area and into
the base system.

A follow-on commit will include the drivers in the amd64 GENERIC kernel.

Import driver source from hyperv-20130627 vendor branch.

Import driver source from hyperv-20130502 vendor branch.
