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.

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 Trac tickets were found above:
Ticket 158 --> https://svn.open-mpi.org/trac/ompi/ticket/158
- use the OPAL functions for PATH and environment variables
- make all headers C++ friendly
- no unamed structures
- no implicit cast.
Plus a full implementation for the orte_wait functions.

Clean up the remainder of the size_t references in the runtime itself. Convert to orte_std_cntr_t wherever it makes sense (only avoid those places where the actual memory size is referenced).
Remove the obsolete oob barrier function (we actually obsoleted it a long time ago - just never bothered to clean it up).
I have done my best to go through all the components and catch everything, even if I couldn't test compile them since I wasn't on that type of system. Still, I cannot guarantee that problems won't show up when you test this on specific systems. Usually, these will just show as "warning: comparison between signed and unsigned" notes which are easily fixed (just change a size_t to orte_std_cntr_t).
In some places, people didn't use size_t, but instead used some other variant (e.g., I found several places with uint32_t). I tried to catch all of them, but...
Once we get all the instances caught and fixed, this should once and for all resolve many of the heterogeneity problems.
This commit was SVN r11204.
1. Introduces a flag for the type of buffer that now allows a user to either have a fully described or a completely non-described buffer. In the latter case, no data type descriptions are included in the buffer. This obviously limits what we can do for debugging purposes, but the intent here was to provide an optimized communications capability for those wanting it.
Note that individual buffers can be designated for either type using the orte_dss.set_buffer_type command. In other words, the buffer type can be set dynamically - it isn't a configuration setting at all. The type will default to fully described. A buffer MUST be empty to set its type - this is checked by the set_buffer_type command, and you will receive an error if you violate that rule.
IMPORTANT NOTE: ORTE 1.x actually will NOT work with non-described buffers. This capability should therefore NOT be used until we tell you it is okay. For now, it is here simply so we can begin bringing over parts of ORTE 2.0. The problem is that ORTE 1.x depends upon the transmission of non-hard-cast data types such as size_t. These "soft" types currently utilize a "peek" function to see their actual type in the buffer - obviously, without description, the system has no idea how to unpack these "soft" types. We will deal with this later - for now, please don't use the non-described buffer option.
2. Introduces the orte_std_cntr_t type. This will become the replacement for the size_t's used throughout ORTE 1.x. At the moment, it is actually typedef'd to size_t for backward compatibility.
3. Introduces the orte_dss.arith API that supports arbitrary arithmetic functions on numeric data types. Calling the function with any other data type will generate an error.

for the type to be packed / unpacked when dealing with sized types (like
size_t) so that the dss_unpack code to deal with types of different sizes is
activated. Necessary for proper 32/64 interoperability.

- 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)
This commit was SVN r8985.
