Add a flag to dk_dump for virtual disk devices.

If a disk is backed by a physical medium other than itself, such as
cgd(4), then it passes DK_DUMP_RECURSIVE to disable the recursion
detection for dk_dump.

If, however, a device represents a physical medium on its own, such
as wd(4), then it passes 0 instead.

With this, I can now dump to dk on cgd on dk on wd.

Set disk product name as disk type. The information can be queried through

Handle the SATA to USB external enclosure sold by "Sabrent" and
made by JMicro (vendor=0x152d product=0x0578). This bridge does
not understand FUA, so add a quirk for it.

The atapibus detach path did hold the channel mutex while calling into autoconf,
which would trigger a panic when unplugging a USB ATAPI CDROM.

Align detach code for scsibus and atapibus to fix this.

Also avoid races when detaching devices by replacing callout_stop with
callout_halt.

Make scsipi framework MPSAFE.

Data structures are now protected by a per-adapter mutex at IPL_BIO
that is created by the scsibus or atapibus instance when the adapter
is configured.
The enable reference counter and the channel freeze counter which are
currently used by HBA code before the adapter is configured, are made
atomic.
The target drivers are now all tagged as D_MPSAFE.

Almost all HBA drivers still require the kernel lock to present,
so all callbacks into HBA code are still protected by kernel lock
unless the driver is tagged as SCSIPI_ADAPT_MPSAFE.

TODO: refactor sd and cd to use dksubr.

We have three sets of DTYPE_ constants in the kernel:
altq Drop Type
disklabel Disk Type
file Descriptor Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.
