Added logging flag to log_append() to change log behaviour

Valid flags are:

* LOGFL_NORMAL
Log all messages to the log context, and send log message to stderr
on errors

* LOGFL_NODUPS
Log only unique messages.  Duplicated messages will be removed

* LOGFL_NOSTDERR
Don't write to stderr, even if errors occur
