When passing an empty string as a directory, the function would produce
filenames starting with a slash even when the given file_name is not an absolute
path. Defaulting to the root directory is likely never intended and might
conveivably be dangerous. The middle "/" is now skipped also if dir is an empty
string.
- Use `-b` most everywhere, it will save time.
- Start some intel tests upon the input file being fully read instead of
at an arbitrary time.
- Improve termination condition for some sumstats/cluster tests.
- Filter uninteresting output from some supervisor tests.
- Test for `notice_policy.log` is no longer needed.
This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.
