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.

906e8bf1d1 Replace the ompi_pointer_array with opal_pointer_array. The next step
(sometimes after the merge with the ORTE branch), the opal_pointer_array
will became the only pointer_array implementation (the orte_pointer_array
will be removed).

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:

e00c6053dc Commit 1 of 2: be consistent in the MPI_*_F2C functions for the
handling of invalid Fortran handles.  Per MPI-2:4.12.4, if we get an
invalid Fortran handle, we should return an invalid C handle.  Before
this commit, we checked if the fortran handle index was out of range
(i.e., <0 or >sizeof(array)).  If so, we used to return MPI_*_NULL
(i.e., a valid C handle).  But to be faithful to MPI-2:4.12.4, we
now return NULL (an invalid C handle).

If the fortran index is in bounds but is an index for an MPI object
that has already been freed, the code already returns NULL because the
entry in the array will be NULL (i.e., we already did what
MPI-2:4.12.4 said for this case).

Hence, this commit makes the handling of invalid fortran handles in
the MPI_*_F2C functions be uniform: we always return NULL.

Commit 2 of this will be to edit just about every C interface function
(!) to ensure that MPI handles are not NULL.  Otherwise, if the user
calls a fortran interface function with an invalid handle, the fortran
interface function will call MPI_*_F2C and blindly pass the result to
the back-end C function.  The C function will eventually end up trying
to dereference it -- segv.  Having a run-time check for NULL and
invoking an MPI exception is far more social (e.g., the user can get a
stack trace out of MPI_ABORT) and consistent (i.e., we're already
checking for MPI_*_NULL in the C interface functions).

Since all the C interface functions have all the machinery for
run-time parameter checking, and they all already check for
MPI_*_NULL, it's easy enough to add another check for NULL.

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)
