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.
This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.
