Add -fwrapv to CFLAGS for the kernel. This essentially un-reverts r259045.
The C standard undefines behavior when signed integers overflow. The
compiler toolchain has become more adept at detecting this and taking
advantage of faster undefined behavior. At the current time this has the
unfortunate effect of the clock stopping after 24 days of uptime.
clang makes no distinction between -fwrapv and -fno-strict-overflow. gcc
does treat them differently but -fwrapv is mature in gcc and is the
behavior are actually expecting.

Add support for probing the SCSI VPD Extended Inquiry page (0x86).
This VPD page is effectively an extension of the standard Inquiry
data page, and includes lots of additional bits.
This commit includes support for probing the page in the SCSI probe code,
and an additional request type for the XPT_DEV_ADVINFO CCB. CTL already
supports the Extended Inquiry page.
Support for querying this page in the sa(4) driver will come later.

Probe the Extended Inquiry page, if the device supports it, and
return it in response to a XPT_DEV_ADVINFO CCB if it is requested.
sys/cam/scsi/cam_ccb.h:
Define a new advanced information CCB data type, CDAI_TYPE_EXT_INQ.
sys/cam/cam_xpt.c:

Add comment about why checking for 0xff is OK. There's two bits in the

pertain to a particular change.
This change removes the "What's New" section, integrating
