Replicator 100428

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

Updated parts:
* Updated dm_splice_list() API.
* Removed old code from dm_tree_preload_children().
* Renamed failed_lvs -> failed_lvnames.
* Switched vgs_list to cmd_vg and updated API slightly
* Extracted nonrelated change in front of patchset (return ECMD_FAILED)

* Previous set had wrong month number.
* Converted Makefiles.
* Renamed some functions (removed lvm_ prefix).
* Renamed vg_name_list -> vgs_list.
* Roved 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.

Zdenek Kabelac (23):
Return ECMD_FAILED for break
Add dm_list_splice() for list join.
