[bug#41490] [PATCH 0/5] Add pEp (pretty Easy privacy)

[Hartmut Goebel]

This adds the build tools and libraries for pretty Easy Privacy, a library for
automatic key management and encryption of messages.

How shall we name the packages here?
I'd appreciate feedback to the package names, since the original packages have
quiet uncommon names:

- pEpEngine -> pep-engine (main library)
- libpEpAdapter -> intermediate layer library
- pEpPythonAdapter -> python-pep-adapter
- pEpJNIAdapter -> java-pep-adapter

The project as other packages like these:
- pEpQtAdapter
- pEpJSONServerAdapter
- pEpObjCAdapter

In Arch Linux AUR packages are named pep-engine, libpep-adapter,
python-pep-adapter, pep-jni-adapter, pep-qt-adapter.

Hartmut Goebel (5):
  gnu: Add yml2.
  gnu: Add pep-engine.
  gnu: Add libpepadapter.
  gnu: Add python-pep-adapter.
  gnu: Add java-pep-adapter.
