qscopedvaluerollback: add convenience constructor
It's a common need to assign a variable to something when entering a
code block, and then revert it upon exit. qscopedvaluerollback can
be used for this. But as a convenience, this patch adds an
extra constructor so that you can "protect" and set a variable
in one go instead of using two lines.
