use ebx in inline assembly. For the beta, just don't inline the 64
bit atomic compare and swap on IA32 (cmpxchg8 requires use of ebx).
Any caller of the function will fall back to the non-inline version.

A new file has been added (new_pack.c). It is not yet used but inside I try to create
a more cleaner ppack/unpack function. There is still work in progress on this file.
New !!! In debug mode there is a gdb friendly function where you can set a breakpoint
(ompi_ddt_safeguard_pointer_debug_breakpoint) in order to see what's the status of
the convertor and the internal veraible when the ddt engine try to do a pack/unpack
outside the user buffer.
A new field in the convertor structure. This field get initialized in the convertor_init_for_*
functions and point to the datatype description that have to be used by the pack/unpack
functions. Until now each one of them have a test in the begining to detect which data
representation to be used (normal or optimized). Now this field point directly to the correct
one.
Change names for local variable to be easier to understand what they are supposed to
represent.
Add a new function ompi_convertor_set_start_position which can be used to set the
current position in the convertor depending on the datatype attached to the convertor.
An improved version of convertor_init_generic which work wiith convertors comming from a cache.
Only the necessary field get modified.
A lot more cleanups ...
This commit was SVN r5950.
Use the correct indentation.
Now we can force the progress function to grab as many events as possible
(in order to avoid starvation for the send queue).
Add more elems in the unexpected queue (internal buffers use to temporary
store the data for the unexpected messages).
Decrease the number of variables in some functions (cleanup).
Avoid using goto ...

Split the datatypes in 3 categories:
1. basic datatypes: count always one and the datatype is always
contiguous
2. complex datatypes composed on one basic type with a count. Most of
the time these datatypes will be contiguous.
3. complex datatypes composed by 2 basic types. Depending on the
architecture these types can be non contiguous.
Reorder the defines to match the previous categories. Add some
comment to describe the changes in the files.
Clean-up the flags:
- DT_FLAG_PREDEFINED is attached to all predefined datatypes.
- DT_FLAG_CONTIGUOUS is attached to all contiguous one. This flag is
detected at runtime depending on the architecture.

-bynode and -byslot orterun command line parameters now set a single
MCA param (ras_base_schedule_policy) which is looked up by the
following components to decide which RAS base API function to invoke:
ras base bjs
ras base host

* turn off echoing on the pty (which was what r5925 was trying to
do).
With this patch, stdin forwarding to rank 0 looks good, with the exception
of the initialization delay until stage gate 1.

setup. Now uses fork() instead of ssh if the target nodename is the
same as the current nodename (which will happen if the user gave
"localhost" or just the hostname without the domain) or if the
target nodename is local according to ompi_ifislocal() (which will
happen if the user gave a FQDN)

orte_system_info.nodename so that cleanup and the like occur
correctly. Otherwise, the daemon on localhost and an MPI process
can have different ideas on what the local nodename is, and that
lead to all kinds of badness with both process killing and cleanup.
Also fixes the annoying ssh keys problem when sshing to localhost.
- modify the rsh pls to ssh to localhost if the target nodename is the
same as orte_system_info.nodename AND is not resolvable (ie, ssh to
would fail). Otherwise, ssh to nodename. This should work around
the issues Ralph was seeing with ssh failing on his laptop (since
the above change undid the previous fix to this problem).
- Small change to ompi_ifislocal() to squelch a warning message about
unresolvable hostnames when checking to see if a name is, in fact,
resolvable.
- Force ORTE process to have same nodename field as it's starting
daemon (assuming it was started using the fork pls), so that the
fork pls can properly kill the process, and cleanup its session
directory on abnormal exit.

of the started job (which should be rank 0 of the started MPI job). Still
some issues for Tim / Ralph to work out (below). Only works from MPI_Init
onward. Remaining issues:
- Need to move the orte_rmgr_urm_wireup_stdin() call from STG1 to
when everyone sets LAUNCHED state. Tim/Ralph are going to look
at adding this code
- stdin frags are not properly acked, leading to some shutdown
workarounds. Tim is going to look at this one.
- Probably somehow related to the 2nd point, stdin text appears
to be echoed by the IOF framework
