8d6e0c9562 Fix restart of clvmd using -S switch
- allocate environment dynamically (still missing some limit?)
 - try to recover, if destroy failed (do not destroy lvm here) and free memory
 - check strdup() return codes
 - report failure to log
 - do not print NULL in exclusive lock loop

31943693c7 Require partial option in lvchange --refresh for partials LVs.
We must not refresh LV if some PVs are missing and partial activation
was not requested.

ee83186ecc Add support for dm-mod module autoload.
A kernel patch is on its way for 2.6.35 adding support for dm-mod module
autoload. Udev v155 and higher is able to read static node information given
in modules.devname (extracted by depmod before) and will create such nodes
at its start. The first access to such node will load the module automatically
(directly in kernel) before the actual read/write operation is processed.

8eed925e17 Replicator: update activate code for vgchange
Activate only the first replicator-dev LV, that activates all other
related LVs from Replicator. In case of error during this activation,
it will not retry again for other heads (less confusing error log).

3ed801fb95 Fix scripts/relpath.awk to work with mawk
length(array) is specific to GNU awk and doesn't work in mawk.
Use a return value of "split" function to indicate array size, this is
supported in both gawk and mawk.

This patch fixes the following errors during "make install" when mawk is
installed as a default awk.

mawk: scripts/relpath.awk: line 25: illegal reference to array from
mawk: scripts/relpath.awk: line 25: illegal reference to array to

9249fb12b8 Replicator: activate checks for missing vgs

f467cd17a1 Replicator: use cmd_vg for process_each_lv_in_vg()
As for _process_one_vg() we need similar retry loop for
process_each_lv_in_vg(). This patch retries to process
failed LVs with reopened VGs.

Patch does not add any extra repeated invocations if there is not
found any missing VG during LV processing.

2ad07c0716 Replicator: use cmd_vg list for _process_one_vg()
Patch modifes behavior of _process_one_vg().

In the first pass vg_read() collectis for replicator sorted list of
additional VGs during lock_vol().
If any other VG is needed by the replicator and it is not yet opened
then next iteration loop is taken with all collected VGs.

Flag vg->cmd_missing_vgs detects missing VGs.

12569ccb03 Replicator: add sorted cmd_vg list
Introduce struct cmd_vg to store information about needed
volume group name, vgid, flags and the pointer to opened VG.

Keep VGs list in alphabetical order for locking order.

Introduce functions:
cmd_vg_add() add new cmd_vg entry.
cmd_vg_lookup() search cmd_vgs for vg_name.
cmd_vg_read() open VGs in cmd_vgs list.
cmd_vg_release() close VGs in reversed order.

0a02d30ea4 Replicator: extend volume_group with list of VGs and flag
Add pointer to linked list of opened VGs. List temporarily keeps
the information about needed or locked and opened VGs for replicator target.

Also add cmd_missing_vgs flag information for quick check and
also for possible continuos process_each_lv() usage where we need
to detect whether failure has been caused by missing VG or
some other reason.

node (i.e. replicator control target) before deactivation of parent node
(i.e. replicator-dev target).

This patch presents no functional change to current dtree - only
replicator target currently sets presuspend node for dev nodes.
