introduced semaphored_job_count, renamed unclaimed_job_count-->ready_job_count, changed reporting, fixed hive_capacity=0

switched Queen to become descendent of Hive::DBSQL::ObjectAdaptor and removed _generic_fetch from it

Dropped 'BLOCKED' job status and introduced 'SEMAPHORED' status that is maintained in sync with semaphore_counts; less confusing and more efficient (with new 3-part index)

record each Workers log_dir in the database; simplified the log_dir code and renamed cmdline options accordingly

replaced rc_id by resource_class_id throughout the schema and added the foreign keys on resource_class_id

moved submit_workers_max/pending_adjust/total_workers_max/meadow_options into Config, but they are still configurable from BK's commandline via config_set(); lots of code cleanup on the way

bugfix+feature: -local_cpus renamed into -total_workers_max and so made available for any meadow (not just LOCAL). Plus some renames

Removed maximise_concurrency and added analysis_stats.priority to guide the scheduler; improved scheduler and LSF meadow

rationalized dynamic batch_size estimation: it is now done centrally both for single Workers (claiming) and the Queen (sync procedure)
