[ros-users] [Discourse.ros.org] [Next Generation ROS] Adding clang thread safety analysis for ROS2 core packages

[Emerson Knapp via Discourse.ros.org]

Proposal for phasing/staging moving forward on this:

1. Create `rcpputils` package with annotation macros
1. Enable `-Wthread-safety` on `rmw_fastrtps` and migrate to the private-mutex pattern for `TopicCache`
1. Enable `-Wthread-safety-negative` on `rmw_fastrtps` and add negative capability annotations where needed
1. Perform 2&3 on the other rmw implementations
