 * some logtypes through use of FMDUMP_AGGREGATE_IGNORE in the process
 * environment, setting it to a comma-separated list of log labels and/or
 * log filenames to ignore).
 *
 * We will not attempt to perform a chronological sort across all log records
 * of all files.  Indeed, we won't even sort individual log files -
 * we will not re-order events differently to how they appeared in their
 * original log file.  This is because log files are already inherently
 * ordered by the order in which fmd receives and processes events.
 * So we determine the output order by comparing the "next" record
 * off the top of each log file.
 *
 * We will construct a number of log record source "pipelines".  As above,
 * the next record to render in the overall output is that from the
 * pipeline with the oldest event.
 *
 * For the case that input logfiles were listed on the command line, each
 * pipeline will process exactly one of those logfiles.  Distinct pipelines
 * may process logfiles of the same "type" - eg if two "error" logs and
 * one "fault" logs are specified then there'll be two pipelines producing
 * events from "error" logs.
 *
 * If we are merging all known log types then we will construct exactly
 * one pipeline for each known log type - one for error, one for fault, etc.
 * Each pipeline will process first the rotated logs of that type and then
 * move on to the current log of that type.
 *
 * The output from all pipelines flows into a serializer which selects
 * the next record once all pipelines have asserted their output state.
 * The output state of a pipeline is one of:
 *
 *	- record available: the next record from this pipeline is available
 *	  for comparison and consumption
 *
 *	- done: this pipeline will produce no more records
 *
 *	- polling: this pipeline is polling for new records and will
 *	  make them available as output if/when any are observed
 *
 *	- processing: output state will be updated shortly
 *
 * A pipeline iterates over each file queued to it using fmd_log_xiter.
 * We do this in a separate thread for each pipeline.  The callback on
 * each iteration must update the serializer to let it know that
 * a new record is available.  In the serializer thread we decide whether
 * we have all records expected have arrived and it is time to choose
 * the next output record.
