Inline the one-line helpers in src/ninep at their call sites

reads, paneFileNamed, topFileNamed, serialNamed, attrReply, makePane,
events.pending, mtimeOf, versionOf, dirOf, cellOf, shiftBy, flagOf,
stageIndexLine, ctlLen, listenersLen, activeSerial, fontName and
Serials.has each wrapped a line or two used once or twice; the logic now
reads where it is used. Helpers that do several things or are shared
widely (bodyOf, fileOf, dirtyOf, nameOf, kindOf, clip, readRange,
readFlag, pty's answer and waitingRun, nextSerialAfter) stay.
