External array mapping MODULES_te values to their name strings.

External array mapping MODULES_te values to their name strings.

Indexed by MODULES_te values. Used by the log subsystem to prefix each log message with the originating subsystem name, and by the CLI to display module names.

The order and count of entries must remain in sync with MODULES_te.
