Replicator 100412

Rebased set of replicator patches.
Log creation code is still kept separately as many changes are still on going in this code.

Updated parts:

* previous set had wrong month number.
* converted Makefiles.
* renamed some functions (removed lvm_ prefix).
* renamed vg_name_list -> vgs_list.
* moved code from validation to segment checking.

* Added dm_list_splice
* Changed API for process_each_lv_in_vg()
* lock_lv_vol() detects missing VGs before calling lock_vol().

* Using common typedef between dm and lvm part for operation mode.
* Minor code reoganization based on review
* Extended validation code.
* Added manpages updates to patches to document API
still this is ongoing task to make all the options working.
* API around vg_name_list which is now autonomous entity.
* Processed VG contains list of opened VGs and flag for missing VGs.
