Adding sys/nfs/nfssvc.h and sys/nfs/nfs_nfssvc.c in preparation for sharing of the nfssvc() system call between nfsserver and the nfsv4 server. Building of nfs_nfssvc.c will be committed later, at the time the .c files in sys/nfsserver are updated. To do so now would result in nfssvc() multiply defined.

Modify the experimental NFSv4 server so that it posts a SIGUSR2 signal to the master nfsd daemon whenever the stable restart file has been modified. This will allow the master nfsd daemon to maintain an up to date backup copy of the file. This is enabled via the nfssvc() syscall, so that older nfsd daemons will not be signaled.

Add kernel support for NFSSVC_ZEROCLTSTATS and NFSSVC_ZEROSRVSTATS so that they can be used by nfsstat(1) to implement the "-z" option for the new NFS subsystem. MFC after: 2 weeks 2011-05-04 13:36:18 +00:00			`#define NFSSVC_ZEROCLTSTATS 0x01000000 /* modifier for GETSTATS */`

Add two new options to the nfssvc(2) syscall that allow processes running as root to suspend/resume execution of the kernel nfsd threads. An earlier version of this patch was tested by Vincent Hoffman (vince at unsane.co.uk) and John Hickey (jh at deterlab.net).
