During merge I split the test for bro_init/bro_done/bro_script_loaded
event errors into individual tests since the other testing of the zeek
versions of those events seemed fine to otherwise keep.
* origin/topic/robin/631-deprecation-v2:
Update NEWS for naming changes.
Small cleanup and updating submodules.
Remove test for legacy plugin.
Remove legancy symlinks in aux/.
Add warnings when loading scripts ending in ".bro", or using legacy environment variables.
Fix missing rename.
No longer symlink local.zeek to local.bro.
Update notice user agent.
Remove old_comm_usage_is_ok.
Remove bro-config.h.in and bro-path-dev.in.
Change Bro wrapper script to now abort when old executable names are still used.
Remove APIs that were explicitly deprecated to be removed in 3.1.
