aa8391f888 Local and global coordinators should be the only ones involved in the
movement of checkpoint files. This reduces the overhead on the applicaiton.

7437f37e96 This commit contains the following:
* 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.

b5fc722c35 Add a flag to 'pretend' to do filem in snapc. This is useful when doing
performance characterization, and should not be used by anyone doing anything
else since it will not produce a globally consistent checkpoint in this mode.

edb2cbd150 In r15007 the --bootproxy orted argument was removed to support daemon reuse.
The SnapC Full local Coordinator used this argument to attach to the job the
daemon would be launching. So once this option was removed C/R support broke.

This commit has the local coordinator attach to the job just before it is
launched by the ODLS module. This is a much cleaner solution, and will
eventually allow the SnapC modules to attach to multiple jobs launched 
on a single machine.

This commit fixes the C/R regression introduced in r15007.

dadca7da88 Merging in the jjhursey-ft-cr-stable branch (r13912 : HEAD).
This merge adds Checkpoint/Restart support to Open MPI. The initial
frameworks and components support a LAM/MPI-like implementation.

This commit follows the risk assessment presented to the Open MPI core
development group on Feb. 22, 2007.

This commit closes trac:158

More details to follow.
