* Because frameworks/analyzer is loaded via init-frameworks-and-bifs the
dpd functionality (really just dpd.log and disabling of analyzers) is
now enabled even in bare mode.
* Not sure we need to keep frameworks/base/dpd/__load__.zeek around
or can just remove it right away.
* 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"
