Merge remote-tracking branch 'origin/post_release' into develop
disable one check in TestUDPListener (thanks L72INpUX)
- add hints what possible went wrong
bump version in changelog.txt
fix some linux_static errors
fix typo in cppcheck.sh (enables parallel checking)
update to cppcheck 1.55 + fix some warnings/errors
fix some more cppcheck warnings
update shard (fix cppcheck warnings)
nice/ionice 7z in make_installer.sh
fix spring-multithread linux_static build
note, it's more a hack. At best default & mt cmake scripts should share this content!
linux_static: static link libstdc++ & libgcc
linux_static: buildbot: use readelf instead of ldd to check dependencies
readelf only shows the direct dependencies, while ldd shows indirect (dependencies of dependencies) ones next to the direct ones.
With `ldd -v` you get something like a table, but still need to investigate it to understand what's direct and what's indirect, so readelf is better.
Don't waste time iterating unconsumed packets
Make sure MT runs at ~100% Sim CPU during catch-up
