Adjustments during merge:
- kept the UNKNOWN Log::ID as placeholder value
- changed the coverage.find-bro-logs test to check for arbitrary $path
field values instead of just string literals
- don't force EnumVal to unsigned integer since the relevant union member
is the signed integer and added the relevant enum values/types to
.bif files for easier access
- compare FILE* versus file name to check for stdout equality (don't
think it matters much, just a bit more efficient)
- minor whitespace/style tweaks
* origin/topic/dev/print-to-log:
Added a non boolean configuration and other changes as suggested by Jon
Allow Print Statements to be redirected to a Log# This is a combination of 3 commits.
* 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"
