Mark Johnston f7db0c9532 vmspace: Convert to refcount(9)
This is mostly mechanical except for vmspace_exit().  There, use the new
refcount_release_if_last() to avoid switching to vmspace0 unless other
processes are sharing the vmspace.  In that case, upon switching to
vmspace0 we can unconditionally release the reference.

Remove the volatile qualifier from vm_refcnt now that accesses are
protected using refcount(9) KPIs.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
