[PATCH v2 0/2] Add new "signature" atom

Hi,

Thanks for the review.

Changes since v1:

    PATCH 1/2 -
	Changed the condition so that prereq GPG2 will only fail
	if we have GPG v0.* or v1.* instead of failing when we
	don't have v2.* (this will have an effect if in the future
	GPG v3.*, v4.* were introduced).

    PATCH 2/2 -
	Renamed the setup tests to be more clear about their purpose.

    Common to both the patches is the change where we introduce a
    newline to a file. Use "echo >" instead of "echo "" >".

I have also rebased this to be on top of v2.41.0, the previous version was on top of v2.41.0-rc0.
