Lots of improvements, including restructring the caching and management

of vnodes and objects.  There are some metadata performance improvements
that come along with this.  There are also a few prototypes added when
the need is noticed.  Changes include:

1) Cleaning up vref, vget.
2) Removal of the object cache.
3) Nuke vnode_pager_uncache and friends, because they aren't needed anymore.
4) Correct some missing LK_RETRY's in vn_lock.
5) Correct the page range in the code for msync.

Be gentle, and please give me feedback asap.
