about linkers, have all OPAL, ORTE, and OMPI components '''not'' link

only static libraries. Previously, we were linking the libraries into
directly into the common, btl, and mtl code. This seemed to work fine
for me on my Opteron Fedora box, but caused Lisa some issues (PtlNIInit
would succeed, but the network handle would fail when used with
PtlEQAlloc).
Instead, link the portals libraries directly into libmpi and not at
all into the common, btl, or mtl components. THen use some linker
tricks to force the linker to bring in the public interface for the
reference implementation (which thankfully is pretty small).

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.

The original code was not compensating for the space used by the header.
When memory got tight, the allocator would return a pointer to memory that
did not exist resulting in a SEGV for the application. This is a partial
fix for ticket #929.

originally suggested by Ralf Wildenhues, to try to speed autogen, configure,
and make (and possibly even make install). Use automake's include directive
to drastically reduce the number of Makefile files (although the number of
Makefile.am files is the same - most are just included in a top-level
Makefile.am). Also use an Automake SUBDIRs feature to eliminate the
dynamic-mca tree, which was no longer really needed. This makes adding
a framework easier (since you don't have to remember the dynamic-mca
tree) and makes building faster (as make doesn't have to recurse through
the dynamic-mca tree)

AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.
