wslog: Add support for domain filtering

A domain filter can be given in the environment variable
'WS_LOG_DOMAINS' or in a command-line options "--log-domains".

The filter is specified as a comma separated case insensitive list,
for example:

    ./tshark  --log-domains=main,capture

Domain data type switches from an enum to a string. There is no
constaint on adding new domains, neither in code or at runtime.
The string format is arbitrary, only positive matches will produce
output.
