f45dd069bd FT: fix compilation using --with-ft (1/5)
Enabling the FT code breaks compilation (again). This series
tries to fix the compiler errors. This is again only fixing
the compiler errors without any warranty that the result
might actually support FT again.

This first patch moves orte_cr_continue_like_restart from ORTE
to opal_cr_continue_like_restart in OPAL. This only leaves three
calls from OPAL to ORTE in the FT code. As it is not yet 100%
clear how to handle these calls the code orte_sstore.set_attr()
has been #ifdef'd out for now.

e12ca48cd9 A number of C/R enhancements per RFC below:
http://www.open-mpi.org/community/lists/devel/2010/07/8240.php

Documentation:
  http://osl.iu.edu/research/ft/

Major Changes: 
-------------- 
 * Added C/R-enabled Debugging support. 
   Enabled with the --enable-crdebug flag. See the following website for more information: 
   http://osl.iu.edu/research/ft/crdebug/ 
 * Added Stable Storage (SStore) framework for checkpoint storage 
   * 'central' component does a direct to central storage save 
   * 'stage' component stages checkpoints to central storage while the application continues execution. 
     * 'stage' supports offline compression of checkpoints before moving (sstore_stage_compress) 
     * 'stage' supports local caching of checkpoints to improve automatic recovery (sstore_stage_caching) 
 * Added Compression (compress) framework to support 
 * Add two new ErrMgr recovery policies 
   * {{{crmig}}} C/R Process Migration 
   * {{{autor}}} C/R Automatic Recovery 
 * Added the {{{ompi-migrate}}} command line tool to support the {{{crmig}}} ErrMgr component 
 * Added CR MPI Ext functions (enable them with {{{--enable-mpi-ext=cr}}} configure option) 
   * {{{OMPI_CR_Checkpoint}}} (Fixes trac:2342) 
   * {{{OMPI_CR_Restart}}} 
   * {{{OMPI_CR_Migrate}}} (may need some more work for mapping rules) 
   * {{{OMPI_CR_INC_register_callback}}} (Fixes trac:2192) 
   * {{{OMPI_CR_Quiesce_start}}} 
   * {{{OMPI_CR_Quiesce_checkpoint}}} 
   * {{{OMPI_CR_Quiesce_end}}} 
   * {{{OMPI_CR_self_register_checkpoint_callback}}} 
   * {{{OMPI_CR_self_register_restart_callback}}} 
   * {{{OMPI_CR_self_register_continue_callback}}} 
 * The ErrMgr predicted_fault() interface has been changed to take an opal_list_t of ErrMgr defined types. This will allow us to better support a wider range of fault prediction services in the future. 
 * Add a progress meter to: 
   * FileM rsh (filem_rsh_process_meter) 
   * SnapC full (snapc_full_progress_meter) 
   * SStore stage (sstore_stage_progress_meter) 
 * Added 2 new command line options to ompi-restart 
   * --showme : Display the full command line that would have been exec'ed. 
   * --mpirun_opts : Command line options to pass directly to mpirun. (Fixes trac:2413) 
 * Deprecated some MCA params: 
   * crs_base_snapshot_dir deprecated, use sstore_stage_local_snapshot_dir 
   * snapc_base_global_snapshot_dir deprecated, use sstore_base_global_snapshot_dir 
   * snapc_base_global_shared deprecated, use sstore_stage_global_is_shared 
   * snapc_base_store_in_place deprecated, replaced with different components of SStore 
   * snapc_base_global_snapshot_ref deprecated, use sstore_base_global_snapshot_ref 
   * snapc_base_establish_global_snapshot_dir deprecated, never well supported 
   * snapc_full_skip_filem deprecated, use sstore_stage_skip_filem 

Minor Changes: 
-------------- 
 * Fixes trac:1924 : {{{ompi-restart}}} now recognizes path prefixed checkpoint handles and does the right thing. 
 * Fixes trac:2097 : {{{ompi-info}}} should now report all available CRS components 
 * Fixes trac:2161 : Manual checkpoint movement. A user can 'mv' a checkpoint directory from the original location to another and still restart from it. 
 * Fixes trac:2208 : Honor various TMPDIR varaibles instead of forcing {{{/tmp}}} 
 * Move {{{ompi_cr_continue_like_restart}}} to {{{orte_cr_continue_like_restart}}} to be more flexible in where this should be set. 
 * opal_crs_base_metadata_write* functions have been moved to SStore to support a wider range of metadata handling functionality. 
 * Cleanup the CRS framework and components to work with the SStore framework. 
 * Cleanup the SnapC framework and components to work with the SStore framework (cleans up these code paths considerably). 
 * Add 'quiesce' hook to CRCP for a future enhancement. 
 * We now require a BLCR version that supports {{{cr_request_file()}}} or {{{cr_request_checkpoint()}}} in order to make the code more maintainable. Note that {{{cr_request_file}}} has been deprecated since 0.7.0, so we prefer to use {{{cr_request_checkpoint()}}}. 
 * Add optional application level INC callbacks (registered through the CR MPI Ext interface). 
 * Increase the {{{opal_cr_thread_sleep_wait}}} parameter to 1000 microseconds to make the C/R thread less aggressive. 
 * {{{opal-restart}}} now looks for cache directories before falling back on stable storage when asked. 
 * {{{opal-restart}}} also support local decompression before restarting 
 * {{{orte-checkpoint}}} now uses the SStore framework to work with the metadata 
 * {{{orte-restart}}} now uses the SStore framework to work with the metadata 
 * Remove the {{{orte-restart}}} preload option. This was removed since the user only needs to select the 'stage' component in order to support this functionality. 
 * Since the '-am' parameter is saved in the metadata, {{{ompi-restart}}} no longer hard codes {{{-am ft-enable-cr}}}. 
 * Fix {{{hnp}}} ErrMgr so that if a previous component in the stack has 'fixed' the problem, then it should be skipped. 
 * Make sure to decrement the number of 'num_local_procs' in the orted when one goes away. 
 * odls now checks the SStore framework to see if it needs to load any checkpoint files before launching (to support 'stage'). This separates the SStore logic from the --preload-[binary|files] options. 
 * Add unique IDs to the named pipes established between the orted and the app in SnapC. This is to better support migration and automatic recovery activities. 
 * Improve the checks for 'already checkpointing' error path. 
 * A a recovery output timer, to show how long it takes to restart a job 
 * Do a better job of cleaning up the old session directory on restart. 
 * Add a local module to the autor and crmig ErrMgr components. These small modules prevent the 'orted' component from attempting a local recovery (Which does not work for MPI apps at the moment) 
 * Add a fix for bounding the checkpointable region between MPI_Init and MPI_Finalize.

6a72c0f4d1 - As long as a header declares _DECLSPEC functionality
it should include the corresponding _config.h header file.

   Tested on Linux/x86-64

d70e2e8c2b Merge the ORTE devel branch into the main trunk. Details of what this means will be circulated separately.
Remains to be tested to ensure everything came over cleanly, so please continue to withhold commits a little longer

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.

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.

This commit was SVN r14051.
