Update tests Indent Shell improvements - use internal function for checks Use PVs in "" (LV and VG cannot have spaces) Several test very starting 'dmeventd' without annoucing it via prepade_dmeventd. Fix some of test actually.

Implement automatic snapshot extension with dmeventd, and add two new options to lvm.conf in the activation section: 'snapshot_autoextend_threshold' and 'snapshot_autoextend_percent', that define how to handle automatic snapshot extension. The former defines when the snapshot should be extended: when its space usage exceeds this many percent. The latter defines how much extra space should be allocated for the snapshot, in percent of its current size.

tests: rename test to inittest We are getting into problem when we use 'test' for commands like should/not/... So avoid overloading test name and change it to inittest.
