Lustre (mostly locking) unused code removal

From: Oleg Drokin <[email protected]>

This continues the quest for killing unused code in the Lustre client.

Main focus in this set is on Lustre LDLM code - it kills both outright unused code and code that looks like it's used, but in fact also unused as various conditions that would lead to it would only happen on the server. Also LDLM is cleaned up to remove unneeded exported symbols and (almost) all locally used functions are now declared as static.

Also a few patches to llite/lov to remove some unused functions there.

Please consider.
