99144db970 Improve checkpoint/restart support by allowing a checkpoint to progress when the process is *not* in the MPI library. This involves creating a separate thread for polling for a checkpoint request. This thread is active when the MPI process is not in the MPI library, and paused when the MPI process is in the library.
Some MPI C interface files saw some spacing changes to conform to the coding standards of Open MPI.

Changed MPI C interface files to use {{{OPAL_CR_ENTER_LIBRARY()}}} and {{{OPAL_CR_EXIT_LIBRARY()}}} instead of just {{{OPAL_CR_TEST_CHECKPOINT_READY()}}}. This will allow the checkpoint/restart system more flexibility in how it is to behave.

Fixed the configure check for {{{--enable-ft-thread}}} so it has a know dependance on {{{--enable-mpi-thread}}} (and/or {{{--enable-progress-thread}}}).

Added a line for Checkpoint/Restart support to {{{ompi_info}}}.

Added some options to choose at runtime whether or not to use the checkpoint polling thread. By default, if the user asked for it to be compiled in, then it is used. But some users will want the ability to toggle its use at runtime.

There are still some places for improvement, but the feature works correctly. As always with Checkpoint/Restart, it is compiled out unless explicitly asked for at configure time. Further, if it was configured in, then it is not used unless explicitly asked for by the user at runtime.

3e2031e0e3 Finally commit something that has been sitting around in one of my
development trees since last year (had to wait for some intel tests to
run yesterday, so I finally took the time to finish this work):

 * Improve MPI API argument checking by also checking for NULL values
   (especially helps when invalid Fortran MPI handles are passed,
   because the various MPI_*f2c functions are supposed to return an
   "invalid" MPI handle [meaning NULL] when this happens).  So now
   OMPI will generate an MPI exception rather than a segv.
 * Removed a few redundant DATATYPE_NULL checks.
 * Also check for some other forms of "invalid" handles (e.g., already
   been freed, etc.) in some cases.  We could probably be a bit more
   stringent in this regard if we really wanted to.
 * Change MPI_Get_processor_name to zero out the string up to
   MPI_MAX_PROCESSOR_NAME characters, because the MPI spec says that
   the string must be at least that long.  We were already passing
   that length to gethostname(), anyway.

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.

The following SVN revisions from the original message are invalid or
inconsistent and therefore were not cross-referenced:

566a050c23 Next step in the project split, mainly source code re-arranging
- move files out of toplevel include/ and etc/, moving it into the
    sub-projects
  - rather than including config headers with <project>/include, 
    have them as <project>
  - require all headers to be included with a project prefix, with
    the exception of the config headers ({opal,orte,ompi}_config.h
    mpi.h, and mpif.h)

c87babb565 * if start_rank == end_rank, there doesn't seem to be a requirement that
stride == 1, and the Intel tests explicitly test the case with
  strides != 1, expecting them to work
