* Fix some missing includes in a few places. * Add the cr_request() functionality to the BLCR CRS component. We are now dependent upon the 0.6.* series of BLCR. * Made the CR notification mechanism a registered function. This way we can have an OPAL-only version and it can be replaced at runtime with the ORTE version. * Add a 'opal_cr_allow_opal_only' parameter that will enable OPAL-only CR functionality when the user wants it. Default: Disabled. * Fix the placement of a checkpoint request check in MPI_Init * Pull the OPAL notification mechanism into the SnapC framework. * We no longer fork/exec the 'opal-checkpoint' command for local checkpointing, the Local coordinator in the orted does this directly. * The Local and Application coordinator talk together bypassing the OPAL notifiation mechanism. * Optimized the Local <-> App Coordinator communication. * Improved the structure used to track vpid_snapshots in the local coord. * Fix a race condition in which an application under heavy communication load may produce an inconsistent global checkpoint. This commit was SVN r16389.
