cmdline iface - fix to consume input array AND strings totally

strings often enough are generated e.g. via "%s/%s" or "%i" or similar
etc. ... i have poitned to examples, so move to make all strings
consistently stringshared, fix a bug added to the efl thread code
where it accessed and freed array even tho array was consumed (but not
strings) in the set, and the code used free to consume not
stringshare_del. fix other code and tests to match

EXCTLY the kind of bugs and mistakes with this kind of design that i
said would happen more often just happened...
