profiling: create a LOGGER_USER id

Loggers need an ID uniquely identify them for profiling. To help with
loggers registered at runtime (library, plugins), provide a
LOGGER_USER that can be used. It won't provide per-logger details if
they have more than one, but will provide a total for all their
registered loggers.
