This commit adds gpg system integration. This is done through two new packages: gpgbin, which handles the system calls and parsing; and gpg which is mostly a copy of emersion/go-pgpmail with modifications to interface with package gpgbin. gpg includes tests for many cases, and by it's nature also tests package gpgbin. I separated these in case an external dependency is ever used for the gpg sys-calls/parsing (IE we mirror how go-pgpmail+openpgp currently are dependencies) Two new config options are introduced: * pgp-provider. If it is not explicitly set to "gpg", aerc will default to it's internal pgp provider * pgp-key-id: (Optionally) specify a key by short or long keyId Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>
