[PATCH 0/8] X509 (gpgsm) commit signing support

[Henning Schild <henning.schild@siemens.com>]

This series adds support for signing commits with gpgsm.

The first two patches are cleanups of gpg-interface, while the next
four prepare for the introduction of the actual feature in patch 7.
Finally patch 8 extends the testsuite to cover the new feature.

This series can be seen as a follow up of a series that appeared under
the name "gpg-interface: Multiple signing tools" in april 2018 [1]. After
that series was not merged i decided to get my patches ready. The
original series aimed at being generic for any sort of signing tool, while
this series just introduced the X509 variant of gpg. (gpgsm)
I collected authors and reviewers of that first series and already put them
on cc.
