* Code cleanup and rationalization
* Fixed: mca_pml_base_send/recv_request are now allocated before recreation by the PML-V
* Fixed: pointer arithmetic bug in sender based that crashed
* Changed: directory structure. This is one step forward using autogen.sh to build static-components.h (it needs to have the directory structure of a mca framework for this).

semicolons but the new specitifcation string used colons. The text
parser now looks for colons.
* Changed all opal_output() error messages to
much-more-helpful/descriptive opal_show_help() messages.
* A few minor style/indenting fixes

* This commit moves all the openib BTL connection code out of
btl_openib_endpoint.c and into a connect "pseudo-component" area,
meaning that different schemes for doing OFA connection schemes can
be chosen via function pointer (i.e., MCA parameter) at run-time.
* The connect/connect.h file includes comments describing the
specific interface for the connect pseudo-component.
* Two pseudo-components are in this commit (more can certainly be
added).
* oob: use the same old oob/rml scheme for creating OFA connections
that we've had forever; this now just puts the logic into this
self-contained pseudo-component.
* rdma_cm: a currently-empty set of functions (that currently
return NOT_IMPLEMENTED) that will someday use the RDMA connection
manager to make OFA connections.

functions. This file should never be compiled (and wasn't being compiled)
on the Cray machines, so doesn't need to be updated to support CNL.

Application Level Placement Scheduler (ALPS).
This commit was tested under two Cray machines at ORNL: Jaguar (Catamount)
and Rizzo (CNL Test cage). Both machines performed as they should across
the commit.
It is likely that mor changes will follow this the work and environment
stabilizes.
Most of the infrastructure works the same for Catamount and CNL
except for a few bits. Below are the highlights:
Default IFACE Change:
On Catamount we can use PTL_IFACE_DEFAULT, but on the CNL system we have access
to will fail on this interface, and should be set to:
IFACE_FROM_BRIDGE_AND_NALID(PTL_BRIDGE_UK,PTL_IFACE_SS).
So if we detect that we are running with YOD then use the former interface
and if we detect that we are running with ALPS then use the latter.
We will want to pursue a more elegant solution if this interface continues to
change across machines.
PtlGetId and cnos_register_ptlid:
The header suggests that these should never be called when launching with YOD.
But in the ALPS environment the cnos_barrier() will hang forever if these
functions are not called after PtlNIInit(). Since these functions only need to
be called once, and the orte rmgr/cnos component is loaded before the ompi
common/portals componet then just call these functions once in the rmgr/cnos
component.
cnos_barrier_init():
This is a noop for YOD, but critical for ALPS. So be sure to call it before
calling the first barrier in the rmgr/cnos component.
cnos_barrier vs cnos_pm_barrier:
It is suggested the cnos_pm_barrier only be used during finalization
as it will indicate to the launcher (yod or aprun) that the app is about
to complete. It was suggested that we use the regular cnos_barrier() instead.
I want to look into this a bit more to make sure there are not adverse
side effects. A note has been placed in the code to indicate this reasoning.

2GB to 4GB-1 by using long instead of size_t for the sm size.
* it is done to prevent user from running into the ftruncate() in
common sm component (and possibly others) problem that ftruncate
takes an off_t which is a signed long integer. If we use an
unsigned long, it'll run into an invalid argument errno=22.

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.

This mpool will have no btl module owner there was no btl created for
the HCA with no ports, but it will still be tracked in the mpool
framework (i.e., it's available).
If MPI_ALLOC_MEM is called by the app, one of two things will happen:
1. if there's an HCA on the host with some active ports, the openib
btl component will still be in the process space, and therefore
the "mpool with no btl" (MWNB) module will still be able to call
the reg/dereg functions, and all will be fine. However, if
MPI_FREE_MEM is never invoked to free the memory, bad things will
happen during MPI_FINALIZE. The pml is finalized, which finalizes
all the btls. The btls finalize all their mpools and all is fine.
But later we close down the mpool framework which then finalizes
any left over mpool modules, such as MWNB. However, the openib
BTL module functions that the MWNB was registered with are no
longer in the process space, and it segv's while trying deregister
the memory.
2. if there are *no* HCA's on the host with active ports, then the
openib btl will have been unloaded, and when the MWNM tries to
register the memory, the functions it tries to call (in the openib
btl) are no longer there, and we segv.

it to at least compile. If you actually get to the point of invoking
the openib btl progress thread, you'll get a big opal_output warning
that it is pretty much guaranteed not to work.
