* remotes/armbru/tags/pull-monitor-2015-11-26:
  qjson: Limit number of tokens in addition to total size
  qjson: surprise, allocating 6 QObjects per token is expensive
  qjson: store tokens in a GQueue
  qjson: Convert to parser to recursive descent
  qjson: replace QString in JSONLexer with GString
  qjson: Inline token_is_escape() and simplify
  qjson: Inline token_is_keyword() and simplify
  qjson: Give each of the six structural chars its own token type
  qjson: Spell out some silent assumptions
  check-qjson: Add test for JSON nesting depth limit
  qjson: Don't crash when input exceeds nesting limit
  qjson: Apply nesting limit more sanely
  monitor: Plug memory leak on QMP error
