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

* Do not empty the list of in-flight frags during _close(); the OOB
callback will still occur (_send_cb()) and try to remove the frag
from the list, which will then result in an assert failure (debug
builds).
* Add one more fix for a possible problem -- add an extra RETAIN /
RELEASE pair on the endpoint to ensure that it is not actually
freed before all in-flight frags have drained.

Ralph identified the problem, I tracked down ''where'' the fd was
being closed, and Brian figured out ''why'' (and the fix).
What was happening is that a remote process was closing its
stdout/stderr and therefore sending a 0-byte IOF message to mpirun.
mpirun, in turn, closed the iof endpoint associated with that stream
(i.e., stdout/stderr). IOF does this to handle the case where
mpirun's stdin is closed -- this therefore causes the stdin on all the
ORTE-started processes to have their stdin's closed as well.
So the workaround here is to check that if we get a 0-byte IOF message
on a sink (indicating a remote closure), and if that sink is the
special stdout or stderr stream, don't actually close anything in the
local process.

because they are in ORTE, not OMPI. Also, remove the ORTE_PROCESS_NAME macros
in iof base as they are duplicates of the ones that were in ns_types, which
meant that bad things happened if you changed what an orte_process_name_t
looked like.

Accordingly, there are new APIs to the name service to support the ability to get a job's parent, root, immediate children, and all its descendants. In addition, the terminate_job, terminate_orted, and signal_job APIs for the PLS have been modified to accept attributes that define the extent of their actions. For example, doing a "terminate_job" with an attribute of ORTE_NS_INCLUDE_DESCENDANTS will terminate the given jobid AND all jobs that descended from it.
I have tested this capability on a MacBook under rsh, Odin under SLURM, and LANL's Flash (bproc). It worked successfully on non-MPI jobs (both simple and including a spawn), and MPI jobs (again, both simple and with a spawn).

the short version is that we shouldn't set O_NONBLOCK on standard I/O
file descriptors, so we no longer do.

cleanup code in the signal part of the event library
* Only attempt to forward standard input if we have a controlling terminal
(isatty() returns 1) and we are the foreground process OR we do not have
a controlling terminal (isatty() returns 0). If we have a controlling
terminal, check at each SIGCONT if we should change our forwarding,
since our foreground / background status may have changed.
Unfortunately, there isn't a great way in the iof framework to know if
we are capturing a starter's stdin. Use the logic that if it's a source
AND tagged as standard input, it's a starter's stdin. This seems to
work for all the common usages.
Both these need to go to the v1.0 branch.

This should probably go to the v1.0 branch.

discards all of the data in the pty that hasn't been read. This was
leading to data being discarded when files were redirected into
mpirun and read by rank 0 of the job. This was very "not good".
The decision to not use ptys for stdin was made based on what Tim said
that LA-MPI was doing.
This needs to go to the v1.0 branch... Tim should probably review...

- when eof is reached at orterun, send a 0 byte message to peer indicating eof

spining in orte_iof_base_flush() when running
intel_tests/src/MPI_Errhandler_fatal_c
When we close an endpoint by taking it out of the envent handler, we need to make
sure that it fits the criteria to pass through orte_iof_base_flush(), specificly
make sure we clean out the ep_frags list.
Note: This is more of a sanity check, since the endpoint should already be
in this state at the point of closure.
Secondly in orte_iof_base_endpoint_read_handler(), if we determine that it is
necessary to close the endpoint we have to "return" after doing so, otherwise
we add another frag to the endpoint which will cause it to hang in
orte_iof_base_flush().

AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.

add a -I to find the included ltdl.h (vs. a system-installed ltdl.h)
- Clean up kruft in a bunch of Makefile.am's to remove now-unnecessary
AM_CPPFLAGS settings to get static-components.h for each framework
- Move the component_repository API functions out of opal/mca/base/base.h
and into opal/mca/base/mca_base_component_repository.h in order to
decrease unnecessary dependencies (e.g., before this, almost
everything in the tree depended on ltdl.h, which is unnecessary --
only a small number of files really need ltdl.h)
