[LITMUS^RT] preparing a new release

[Björn Brandenburg]

Hi everyone,

as discussed at RTLWS, we would like to push out another maintenance release before RTSS. To this end, I've merged a bunch of prop/ branches into staging. However, I believe there are a couple of recent, as of yet unannounced prop/ branches in the repository. I'm not merging those until it's clear what's ready.

Two action items:

1) Everyone, please test the current staging branch.

2) If you'd like to have another prop/ branch merged, please rebase it on top of the current staging tree and reply to this message with the name of the branch.

Thanks,
Björn
