Script-layer counts, when provided as negative integers in an input
file, got cast to unsigned values because strtoull() does not complain
about negative values. For example, input string "-1" would lead to
value 18446744073709551615 (an all-ones 64-bit int) on x86_64. This is
more likely to be an error than an intent to get very large,
platform-dependent values, so these input lines are now skipped with
according messaging in the reporter.log/stderr.
This also affected ports: -1/tcp got cast to unsigned and only thrown
out because PortVal rejects values > 65535, mapping them to 0. We now
skip such inputs as well.
Updates existing input framework tests to capture the new behavior.
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.
#239
The ascii formatter already was happy to read ports in the form
"42/tcp"; however it emitted a warning message for each line.
This patch fixes this and adds a bit more testing for the existing
behavior.
