hjk 4098be05b2 Utils: Extract a CommandLine structure from a QtcProcess 
We regularly pass around strings or filenames or pairs of strings
or filenames and stringlist etc the in the end will be used
as a kind of "command line", with quite a bit of ad-hoc user
code and QtcProcess::addArg etc to set them up and manipulate them.

Let's have a class for that concept.
