(sometimes after the merge with the ORTE branch), the opal_pointer_array
will became the only pointer_array implementation (the orte_pointer_array
will be removed).

mpi_show_mpi_alloc_mem_leaks
When activated, MPI_FINALIZE displays a list of memory allocations
from MPI_ALLOC_MEM that were not freed by MPI_FREE_MEM (in each MPI
process).
* If set to a positive integer, display only that many leaks.
* If set to a negative integer, display all leaks.
* If set to 0, do not show any leaks.

some time ago (last summer) that included checking for M_TRIM_THRESHOLD and
M_MMAP_MAX, unfortunately we didn't include <malloc.h> which is where these
are define, so disabling sbrk for the registration cache has been busted for
some time.

mca_mpool_base_page_size_log. They are exported by the mpool/base/base.h,
if some other code need them, then it should include this file
instead of having it's own redefinition of these externals.

needlessly registered in multiple different places, and none of them
had a good help string. There was also an inconsistent check for
setting both mpi_leave_pinned and mpi_leave_pinned_pipeline (i.e., it
was only in ob1). This commit moves the registration of these params
to one central place (ompi/runtime/ompi_mpi_params.c, with all other
mpi_* MCA params) and uses globals to propagate the values as
relevant. The error check was also moved to the central location to
ensure that we can consistency everywhere.

udapl/openib/vapi/gm mpools a deprecated. rdma mpool has parameter that allows
to limit its size mpool_rdma_rcache_size_limit (default is 0 - unlimited).

all platforms. The only exceptions (and I will not deal with them
anytime soon) are on Windows:
- the write functions which require the length to be an int when it's
a size_t on all UNIX variants.
- all iovec manipulation functions where the iov_len is again an int
when it's a size_t on most of the UNIXes.
As these only happens on Windows, so I think we're set for now :)

sbrk and the use of mmap(). So rather than checking just for mallopt(),
we should also be checking for those defines when determining if we can
disable giving memory back to the OS or not.

allocation. This is necessary to detect if the user requests a specific
mpool for the allocationi. Searching the key values for a specific mpool
name does not work for the case that the user provides an info object
without mpool specific information (see Ticket #254).
- In the case that the user provides a info object without requesting a
specific mpool we use malloc to allocate buffer instead of returning
NULL (fix for Ticket #254 )

where to look for registrations that were used in the alloc/free code don't
work (because the memory returned from malloc() -- whowever gets around to
calling it) might actually be registered already. So just call malloc
and free directly and avoid the whole issue when leave pinned is on. After
all, you have to pay the registration cost sometime, and if leave pinned
is on, you only have to pay it once. It makes things much simpler to
have that once be at first use rather than during ALLOC_MEM, and as far
as I can read, we're still standards conformant this way.

1) don't need tree if memory is just malloc'd
2) fix memory and free list leak..
3) deregister first and then free... doh..
This commit was SVN r10251.
Added a tree to track memory allocation from MPI_Alloc_mem, this allows us to
free the registrations in a sane fashion.. also should be faster..
This commit was SVN r10248.
2. fix for MPI_Free_mem, was calling deregister but never called mpool_free.. so
we leaked memory. Still an open issue here though, if the memory is alloc'd
and the mpool doesn't create and cache a registration, we will never find the
mpool to free with.

add object size to opal class
no longer need the size when allocating a new object as this is stored in
the class structure

Previous rev. maintained state on the communicator used for acking duplicate
fragments, but the communicator may be destroyed prior to successfull
delivery of an ack to the peer. We must therefore maintain this state
globally on a per peer, not a per peer, per communicator basis.
This requires that we use a global rank on the wire and translate this as
appropriate to a local rank within the communicator.

to let the PML (or io, more generally the low level request manager)
to have it's own release function (what was before the req_fini). This
function will only be called from the low level while the req_free will
be called from the upper level (MPI layer) in order to mark the request
as not used by the user anymore.
From the request point of view the requests will be marked as inactive
everytime we read their status (true for persistent as well). As
MPI_REQUEST_NULL is already marked as inactive, the test and wait functions
are simpler. The drawback is that now we have to change in the
ompi_request_{test|wait} the req_status of the request once we get it's
status.

- 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)
