Merge remote-tracking branch 'origin/topic/dev/print-to-log'

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.
