Pass the CIL context to xlog_write() rather than a pointer to a LSN variable. Only the CIL checkpoint calls to xlog_write() need to know about the start LSN of the writes, so rework xlog_write to directly write the LSNs into the CIL context structure. This removes the commit_lsn variable from xlog_cil_push_work(), so now we only have to issue the commit record ordering wakeup from there.
