[ANNOUNCE] dbus-broker v32

[David Rheinsberg]

Hi

We just released v32. It contains bug-fixes to the D-Bus marshalling
layer, and everyone is recommended to upgrade! This release also
includes initial AppArmor backend support, but this is not yet
finished, nor exposed to the launcher.

https://github.com/bus1/dbus-broker/releases/tag/v32

## CHANGES WITH 32:

* Fix several bugs in the d-bus marshalling layer c-dvar, including
out-of-bound reads.

* Fix ubsan and asan warnings in c-stdaux and related subprojects.

* Add initial infrastructure for the upcoming AppArmor security layer.
This does not include full AppArmor support, yet, but merely prepares
the code-base for it.
