Minor fixes for build problems after reformatting

 New Functionality
 -----------------
 
+- Zeek now supports formatting the C++ code using clang-format. It requires at
+  least clang-format 12.0.1 due to some additions that were made in that version
+  to better support the Whitesmiths style. Zeek also includes a set of python
+  scripts to more easily reformat in the auxil/run-clang-format directory. An
+  example command to reformat the code:
+
+  `python3 auxil/run-clang-format/run-clang-format.py --clang-format-executable `which clang-format-12` -r src -i`
+
