Obsolete branches?!

[irgendwie]

We have two stale branches simcom-pb and qemu-sa-vm from @privatereese. Do we still need them? Are they referenced in any old project and therefore need to stay here? Presumably they contain only user-space applications - can/should we extract them and store them in our archive? Also cc @DK87

Additionally I removed the staging and vagrant-init branches. The first one originates from Genode itself and serves no purpose for us. The second one introduces basis Vagrant integration (#3) but a functional version is already in our main development branch focnados-AR.

simcom-pb contains only a binary file with no usage. So, I guess we can remove it.
qemu-sa-vm is an early version of the qemusavm with two parts:

• /repos/qemusavm with its own package format (Generic packages) - substituted by protobuf/mqtt and rewritten in LL4 2017 😄
• /repos/ecu with its api - transfered into genode-roboteqMotorController

From my side it should be fine to remove both branches @privatereese

removing branches would render testbed unusable.
If you want to remove these branches because newer versions of qemu-sa-vm and simcom-pb exists please consider to change or remove the testbed as well.
You are working at the new versions of the testbed @irgendwie please create a new usable version.
Refer to me for questions.
