Import HyperV Key-Value Pair (KVP) driver and daemon code by Microsoft, many thanks for their continued support of FreeBSD. While I'm there, also implement a new build knob, WITHOUT_HYPERV to disable building and installing of the HyperV utilities when necessary. The HyperV utilities are only built for i386 and amd64 targets. This is a stable/10 candidate for inclusion with 10.1-RELEASE.

hyperv/vss: Add driver and tools for VSS VSS stands for "Volume Shadow Copy Service". Unlike virtual machine snapshot, it only takes snapshot for the virtual disks, so both filesystem and applications have to aware of it, and cooperate the whole VSS process. This driver exposes two device files to the userland: /dev/hv_fsvss_dev Normally userland programs should _not_ mess with this device file. It is currently used by the hv_vss_daemon(8), which freezes and thaws the filesystem. NOTE: currently only UFS is supported, if the system mounts _any_ other filesystems, the hv_vss_daemon(8) will veto the VSS process. If hv_vss_daemon(8) was disabled, then this device file must be opened, and proper ioctls must be issued to keep the VSS working. /dev/hv_appvss_dev Userland application can opened this device file to receive the VSS freeze notification, hold the VSS for a while (mainly to flush application data to filesystem), release the VSS process, and receive the VSS thaw notification i.e. applications can run again. The VSS will still work, even if this device file is not opened. However, only filesystem consistency is promised, if this device file is not opened or is not operated properly. hv_vss_daemon(8) is started by devd(8) by default. It can be disabled by editting /etc/devd/hyperv.conf.
