List of important PRs for 3.3.1, week -3.5

[Wolfgang Bangerth <bangerth at ices dot utexas dot edu>]

Here's an update of the list of PRs that I think are important for 3.3.1. It's 
3.5 weeks until the projected release date.

Of my original list of 66 PRs, 11 have been closed in the meantime, most 
notably some in C++, the only preprocessor bug and some in the target 
section. For some reports, Janis has identified the causing patches, and Dara 
has confirmed a number of the target bugs. libstdc++ and ada haven't seen any 
action, though.

I have added one PR, 11280. That one and 1607 should be a matter of a few 
minutes, if someone wants to handle ground-dwelling fruit. Apart from that, I 
haven't added any other PRs.
