Add xce_job_state_query_req()/xce_job_state_report_req() to request.c,
paginating job IDs / job-state entries across OPCode_jobStateQuery /
OPCode_jobStateReport messages via direct Request.body union arms
(mirroring xce_jobdispatch_req/xce_notify_req's direct-send shape, not
xce_push_data_req's XceData-table multiplexing -- these are dedicated
union arms, not multiplexed push/reply-get traffic). 8 round-trip tests
(normal/empty/multi-page for both query and report, covering all 4
JobStateStatus values and both queried states) all pass.
