84cdf85bd2 cleanup: constify activation usage of lv pointer
Let's enforce cheking of write access to LV by compiler.
Activation part does never need to write anything to LV
so keep LV pointer const.

43d99aab6c Default to checking LV's progress before waiting in _wait_for_single_lv.
Support "wait before testing" using '+' in pvmove and lvconvert
interval.  Doing so overrides the new default of sleeping after checking
the LV's progress.

Sleeping before checking progress can lead to extraneous polldaemons
being left running.  These polldaemons would have otherwise exited had
they checked before sleeping.  Checking progress before sleeping helps
workaround the subtly unreliable nature of "finished" state checking
in _percent_run.

Update test/t-mirror-names.sh to use '+' when providing its lvconvert
interval.

31f55a07db Fix convert polling to ignore LV with different UUID.
When mirror convert polling is started (mainly as backgound process,
in lvchange -a y or in lvconvert itself) it tries to read VG
and LV identified by its name.

Unfortunatelly, the VG can have already different LV under the same name,
and various more or less funny things can happen (note that
_finish_lvconvert_mirror suspends the volume for example).

(the typical example is our testing script which continuously recreates
LVs under the same name in the same VG.)

This patch adds optional uuid parameter which helps to properly
select the monitoring object. For lvconvert polling it is set to LV UUID
and both _get_lvconvert_vg and _get_lvconvert_lv uses it to read proper VG/LV.

(In the pvmove case it is NULL, here we poll for physical volume name).
