30c90f019f hyperv/kvp: Don't mix message status codes and function return values. 
While I'm here, move message status codes to hv_utilreg.h, since they
will be used by the upcoming VSS stuffs.

a6733ed126 Use strlcpy(). I don't believe these are real problems but it's better 
to use a safe idiom.

be930504be Being able to access a path do not necessarily mean we have access 
to a directory. So instead of doing this, we just call mkdir(2)
directly and test if the returned value is 0 or errno is EISDIR.

e72055b7fe 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.
