[PATCH v2 0/9] Configurable policy for handling unstable interfaces

[Markus Armbruster <armbru@redhat.com>]

Option -compat lets you configure what to do when deprecated
interfaces get used.  This series extends this to unstable interfaces.
Works the same way.  Intended for testing users of the management
interfaces.  It is experimental.

To make it possible, I replace the "x-" naming convention by special
feature flag "unstable".  See PATCH 1 for rationale.

v2:
* Rebased
* PATCH 1: Commit message revamped [Kevin], R-bys kept
* PATCH 6: gen_special_features() rewritten [John]
* PATCH 7: disastrous typos fixed [Philippe]

Markus Armbruster (9):
  qapi: New special feature flag "unstable"
  qapi: Mark unstable QMP parts with feature 'unstable'
  qapi: Eliminate QCO_NO_OPTIONS for a slight simplification
  qapi: Tools for sets of special feature flags in generated code
  qapi: Generalize struct member policy checking
  qapi: Generalize command policy checking
  qapi: Generalize enum member policy checking
  qapi: Factor out compat_policy_input_ok()
  qapi: Extend -compat to set policy for unstable interfaces
