[Swan-dev] helper threads can log to whack

I figure it is worth spelling out one of the crypto offload changes.
Helper threads are able to generate messages such as:
002 "westnet-eastnet-ikev2" #1: no Certificate Authority in NSS
Certificate DB! certificate payloads discarded
and have them sent to both whack's console, and the log file.
Previously, helper threads were limited: messages could only go to the
log file, and they lacked the log prefix ("westnet-eastnet-ikev2" #1).
Two things make it work:
- the helper thread is passed a 'struct logger' which contains the
whackfd and the log prefix (as text)
- the helper thread then uses log_message(RC_LOG, logger, ....) and
not libreswan_log() to generate log messages
