Fixes #3673: Move r28790 to v1.7 branch (datatype packing/unpacking fix)

---svn-pre-commit-ignore-below---

r28790 [[BR]]
Fix an issue with the packing/unpacking of datatype representations
identified by Takahiro Kawashima. The packed length was reported as a
max bound and not provided on the unpacking side, so the unpacking
buffer could become out of sync with the content stored after the
packed representation.

The fix force the packing operation itself before reporting the length,
so we always report now the real number of bytes in the packed
representation.

Fixes #3671: Move r28789 to v1.7 (remove OPAL_TRACE)

---svn-pre-commit-ignore-below---

r28789 [[BR]]
Turns out that there was exactly ONE place in all of the OMPI code base that still referred to OPAL_TRACE, though a few places retained the include file for no reason. So no point in letting this sit as it is clearly an unused "feature".
Fixes #3658: Move darwin backtrace removal to v1.7

---svn-pre-commit-ignore-below---

r28727 [[BR]]
Per RFC, remove darwin backtrace, since OS X since 10.5 has supported the
execinfo() interface (which has been the default for OMPI to use on Darwin)
Fixes #3650: Move dist_graph stuff to v1.7

---svn-pre-commit-ignore-below---

r28687 [[BR]]
Add the MPI 2.2 MPI_Dist_graph functionality.

This patch reshape the way we deal with topologies completely. Where
our topologies were mainly storage components (they were not capable
of creating the new communicator), the new version is built around a
[possibly] common representation (in mca/topo/topo.h), but the functions
to attach and retrieve the topological information are specific to each
component. As a result the ompi_create_cart and ompi_create_graph functions
become useless and have been removed.

In addition to adding the internal infrastructure to manage the topology
information, it updates the MPI interface, and the debuggers support and
provides all Fortran interfaces.


r28691 [[BR]]
Remove the item from the list before releasing it.

r28692 [[BR]]
Add the empty basic component where the function pointer from the
base will be copied over. Without such a decoy component the
entire framework will not function correctly.

r28693 [[BR]]
Oops, thanks Jeff for noticing.

r28711 [[BR]]
Set ignores

r28713 [[BR]]
Fix some "malloc of 0 bytes" warnings

r28724 [[BR]]
Do not destroy the sub-communicator until we have freed its attributes,
per the reason cited in the comment in the code.

r28725 [[BR]]
Slightly reorder the code.
