  * \brief Allow use of deprecated Pacemaker APIs
  *
  * By default, external code using Pacemaker headers is allowed to use
  * deprecated Pacemaker APIs. If PCMK_ALLOW_DEPRECATED is defined to 0 before
  * including any Pacemaker headers, deprecated APIs will be unusable. It is
  * strongly recommended to leave this unchanged for production and release
  * builds, to avoid breakage when users upgrade to new Pacemaker releases that
  * deprecate more APIs. This should be defined to 0 only for development and
  * testing builds when desiring to check for usage of currently deprecated APIs.

  * The CRM feature set assists with compatibility in mixed-version clusters.
  * The major version number increases when nodes with different versions
  * would not work (rolling upgrades are not allowed). The minor version
  * number increases when mixed-version clusters are allowed only during
  * rolling upgrades (a node with the oldest feature set will be elected DC). The
  * minor-minor version number is ignored, but allows resource agents to detect
  * cluster support for various features.
  *
  * The feature set also affects the processing of old saved CIBs (such as for
  * many scheduler regression tests).
  *
  * Particular feature points currently tested by Pacemaker code:
  *
  * >=3.2.0:  DC supports PCMK_EXEC_INVALID and PCMK_EXEC_NOT_CONNECTED
  * >=3.19.0: DC supports PCMK__CIB_REQUEST_COMMIT_TRANSACT
