create releases if there are new tags

new mkimage scripts decides the target format

and clear error on first successful build

the buildrepo script reports better information

this is to workaround issue with scaleway arm servers that seem to have
an issue when uploading the iso images.

this replaces abuild-iso

also add options to skip do the full build and to force generation of
release images. This helps when debugging the script.

we need upload logs for arm builders

check if we actually upload anything before we report that new packages
are uploaded.

we dont want prevent to upload a successful built main repo if testing
fails to build.

with v3.1 we no longer generate those

use the directory as payload for the rsync notification instead of
commit. This makes it easier for mirrors to know what to sync.

- set the mqtt_topic after we set git_branch
- set mqtt_user
- fix typo of will_retain

Instead of rolling our own specialized init.d script we simply reuse
the general purpose mqtt-exec init.d script.

This gives use support for will messages and support for subscribing to
more than a single topic.

For now this only indicates if we want make release or not.

aports-build takes care of posting mqtt status messages.

This is so we can configure what buildrepo implementation should be
used.

We also remove the buildrepo_opts option as it becomes redundant.

mosquitto-utils was renamed to mosquitto-clients
