SVN rev 194289 on 2009-06-16 13:05:34Z by emaste
MFC part of r166182 and 179670.
Provide the mutual exclusion between the nfs export list modifications
and nfs requests processing. Lockmgr lock provides the shared locking for
nfs requests, while exclusive mode is used for modifications. The writer
starvation is handled by lockmgr too.
