The framework so far populated data structures with missing fields
even when those fields are defined without the &optional
attribute. When using the attribute, such entries continue to get
populated.
Update tests to reflect focus on unset fields.
A race condition could cause unstable output: if the thread reading the
file is fast, often you see both "pred" functions execute and then both
"line" events execute with both entries already in the table, but if the
thread reading the file is slow, you see pred, event, pred, event, with
only one entry available in the first event.
* Generally increase timeouts for tests that have recent transient
failures
* Change any test that relied on `btest-bg-wait -k` since that's never
going to play with with CI systems. Instead, we always need to have
a well-defined termination condition in the test itself (and most
already did, so didn't really need the `-k` flag anyway).
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.
