Jan Varga 7d3ef83b0f Bug 1686191 - Have a way to specifically report warnings around QM_TRY; r=asuth,sg,dom-storage-reviewers
This patch:
- adds QM_WARNONLY_TRY/QM_NOTEONLY_TRY macros
- adds QM_WARNONLY_TRY_UNWRAP/QM_NOTEONLY_TRY_UNWRAP macros
- adds QM_OR_ELSE_WARN/QM_OR_ELSE_NOTE sub macros
- replaces non-propagating uses of NS_WARNING with redundant messages by
  QM_WARNONLY_TRY
- replaces uses of QM_TRY with orElse by QM_TRY(QM_OR_ELSE_WARN(...))
- replaces uses of QM_TRY inside an extra lambda with QM_WARNONLY_TRY
- replaces uses of QM_TRY with QM_VOID with QM_WARNONLY_TRY.
- replaces uses of QM_TRY with unwanted warnings with QM_NOTEONLY_TRY
- replaces uses of QM_TRY with additional Maybe wrapping for doing a
  fallback with QM_TRY(QM_OR_ELSE_WARN(...))
