java destination: sequence number support for templates

[furiel]

Fixes: #1410

Prior this patch zero was passed as sequence number in java destination templates. This patch propagates the sequence number controlled by the threaded destination driver into LogDestination class, so it will be available in the inherited classes. Thus users can pass it to LogTemplate object when sequence number is used in a template formula.

For example:

LogTemplate logTemplate = new LogTemplate(getConfigHandle());
logTemplate.compile("${SEQNUM}\n");
InternalMessageSender.debug(logTemplate.format(logMessage, 0, logTemplate.LTZ_SEND, getSeqNum()));
