Seperate the VOP_GETATTR shared task into:

Browse source 
- VOP_GETATTR() change to shared locks + namei() updates to support this
- General VFS assertion review and corrections

Move the first to the WIP section, since Jeff Roberson just committed
supporting infrastructure for this in the form of namei's LOCKSHARED.

Leave the second in the New section.
