- Fixing the parts of the `make restdoc` and `make doc` process that were
broken by the last Bro script re-organization
- Generated documentation for Bro scripts derived from BiFs now use the
original BiF source file as the "original source file" link
- Renaming of the internal POLICYDEST definition and other misc places that
refer to "policy" scripts; that terminology doesn't make total sense now
- Added a documentation blacklist reminder test that will fail if there's
scripts that are blacklisted from being documentated because they're still
in progress
- Some minor Bro script changes to fix small @load dependency errors
Addresses #543
Any added prefixes are now used *after* all input files have been
parsed to look for a prefixed, flattened version of the input file
somewhere in BROPATH and, if found, load it.
For example, if "lcl" is in @prefixes, and site.bro is loaded, then
a file named "lcl.site.bro" that's in BROPATH would end up being
automatically loaded as well. Packages work similarly, e.g. loading
"protocols/http" means a file named "lcl.protocols.http.bro" in BROPATH
gets loaded automatically.
