as the IOF components lack the required finalize function. Instead rely on the
module finalize. Read the comment or more informations.

Collect the base 'orted' command line into a base function since most of the
PLS components were duplicating this code. Add AMCA parameter command line
component to the base set.
Add Aggregate MCA parameter support to the following PLS components:
- gridengine
- process
- slurm
- poe
- tm
Improve support for 'rsh' component.
Did/could not support the following components:
- bproc
- proxy
- xcpu
- cnos
- xgrid
The above components had peculiar needs that made it non-trivial to add an
option. The authors of these components need to help in supporting this
new option.
I was only able to test the SLURM and RSH components due to system availability.
The others should work without problem.

- Make it so that all the GPR pointer arrays are allocated initially at 16 elements instead of 512. This saves (on a 64 bit machine) approximately 4*(# procs + # nodes) KB.
- Fix up the segment prealloc function so that preallocating an existant segment is not an error, and make the areas where we do large inserts use it.
Fix the orte_pointer_array to efficiently implement setting its size. Before we just realloced the array one block at a time until the desired size was reached. Now we resize it all in one realloc.

* Remove the connect() timeout code, as it had some nasty race conditions
when connections were established as the trigger was firing. A better
solution has been found for the cluster where this was needed, so just
removing it was easiest.
* When a fatal error (too many connection failures) occurs, set an error
on messages in the queue even if there isn't an active message. The
first message to any peer will be queued without being active (and
so will all subsequent messages until the connection is established),
and the orteds will hang until that first message completes. So if
an orted can never contact it's peer, it will never exit and just sit
waiting for that message to complete.
* Cover an interesting RST condition in the connect code. A connection
can complete the three-way handshake, the connector can even send
some data, but the server side will drop the connection because it
can't move it from the half-connected to fully-connected state because
of space shortage in the listen backlog queue. This causes a RST to
be received first time that recv() is called, which will be when waiting
for the remote side of the OOB ack. In this case, transition the
connection back into a CLOSED state and try to connect again.
* Add levels of debugging, rather than all or nothing, each building on
the previous level. 0 (default) is hard errors. 1 is connection
error debugging info. 2 is all connection info. 3 is more state
info. 4 includes all message info.
* Add some hopefully useful comments

1. Remove a unneeded field, bytes_avail, from orte_buffer_t. It is a calcualed value, and updating it everywhere is worse then just calculating it in the one place it is acutally used.
2. Change it so the default size of a orte_buffer is 128 bytes instead of 1024 bytes. We then double the size of the buffer up to 1024 bytes, then we additively increase the size by 1024 bytes at a time as was done before.

deal with the PLS RSH. Remove support for unknown user (i.e. if the user is
not known by the system, then it shouldn't be allowed to spawn anything).

OPAL_FREE_LIST_WAIT/RETURN will not use locks in a non-threaded build
conditionaly use locks if non-threaded around the OPAL_FREE_LIST_WAIT/RETURN

Tested at 4K processes and seems to work..

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.

* 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.
