d37be0b865 Add possibility to handle precommitted metadata in lvmcache. 
- Add drop_precommitted flag to force drop precommitted metadata
 - add lvmcache_commit_metadata() which upgrades precommitted metadata in cache

No functional change in this patch - just preparation for following change.

3de6df8410 Enforce an alphabetical lock ordering for vgname locks. 
Add a new constraint that vgname locks must be obtained in
alphabetical order.  At this point, we have test coverage for
the 3 commands affected - vgsplit, vgmerge, and vgrename.
Tests have been updated to cover these commands.
Going forward any command or library call that must obtain
more than one vgname lock must do so in alphabetical order.
Future patches will update lvm2app to enforce this ordering.
