Place hostnames and similar information fully under the prison system. The system hostname is now stored in prison0, and the global variable "hostname" has been removed, as has the hostname_mtx mutex. Jails may have their own host information, or they may inherit it from the parent/system. The proper way to read the hostname is via getcredhostname(), which will copy either the hostname associated with the passed cred, or the system hostname if you pass NULL. The system hostname can still be accessed directly (and without locking) at prison0.pr_host, but that should be avoided where possible.
The "similar information" referred to is domainname, hostid, and hostuuid, which have also become prison parameters and had their associated global variables removed.

Commit step 1 of the vimage project, (network stack) virtualization work done by Marko Zec (zec@).
This is the first in a series of commits over the course of the next few weeks.
Mark all uses of global variables to be virtualized with a V_ prefix. Use macros to map them back to their global names for now, so this is a NOP change only.
We hope to have caught at least 85-90% of what is needed so we do not invalidate a lot of outstanding patches again.

Add kernel dump support, based on the ia64 version (which was committed as sparc64/sparc64/dump_machdep.c a while back). Other than ia64 (which uses ELF), sparc64 uses a homegrown format for the dumps (headers are required because the physical address and size of the tsb must be noted, and because physical memory may be discontiguous); ELF would not offer any advantages here.
