* 'action-drop' of https://github.com/LBL-gov/zeek:
Moved verb ACTION_DROP from policy/frameworks/netcontrol/catch-and-release.zeek to base/frameworks/notice/main.zeek.
ACTION_DROP is not only part of catch-n-release subsystem.
Also, historically ACTION_DROP has been bundled with ACTION_LOG, ACTION_ALARM, ACTION_EMAIL... and its helpful that this verb remains in base/frameworks/notice/main.zeek
In the past they were processed on the manager - which requires big
records to be sent around.
This has a potential of incompatibilities if someone relied on global
state for notice processing.
GH-214
* "bro_is_terminating" is now "zeek_is_terminating"
* "bro_version" is now "zeek_version"
The old function names still exist for now, but are deprecated.
For backward compatibility when reading values, we first check
the ZEEK-prefixed value, and if not set, then check the corresponding
BRO-prefixed value.
* All "Broxygen" usages have been replaced in
code, documentation, filenames, etc.
* Sphinx roles/directives like ":bro:see" are now ":zeek:see"
* The "--broxygen" command-line option is now "--zeexygen"
