1. Changed rng_buff_t --> opal_rng_buff_t
2. All global variables obey the prefix rule
3. Old code has been removed 
4. Found a couple of unnecessary includes

e39d9f4080 Per the RFC schedule, add an additive lagged Fibonacci parallel random number generator to OPAL. In order to use, please add the following header to your code: opal/util/alfg.h. See ompi/mca/btl/openib/connect/btl_openib_connect_udcm.c for an example how to seed with opal_srand and invoke the generator with opal_rand. This should be added to
cmr=v1.7.5:reviewer=rhc:subject=Add an OPAL RNG

cf377db823 MCA/base: Add new MCA variable system
Features:
 - Support for an override parameter file (openmpi-mca-param-override.conf).
   Variable values in this file can not be overridden by any file or environment
   value.
 - Support for boolean, unsigned, and unsigned long long variables.
 - Support for true/false values.
 - Support for enumerations on integer variables.
 - Support for MPIT scope, verbosity, and binding.
 - Support for command line source.
 - Support for setting variable source via the environment using
   OMPI_MCA_SOURCE_<var name>=source (either command or file:filename)
 - Cleaner API.
 - Support for variable groups (equivalent to MPIT categories).

Notes:
 - Variables must be created with a backing store (char **, int *, or bool *)
   that must live at least as long as the variable.
 - Creating a variable with the MCA_BASE_VAR_FLAG_SETTABLE enables the use of
   mca_base_var_set_value() to change the value.
 - String values are duplicated when the variable is registered. It is up to
   the caller to free the original value if necessary. The new value will be
   freed by the mca_base_var system and must not be freed by the user.
 - Variables with constant scope may not be settable.
 - Variable groups (and all associated variables) are deregistered when the
   component is closed or the component repository item is freed. This
   prevents a segmentation fault from accessing a variable after its component
   is unloaded.
 - After some discussion we decided we should remove the automatic registration
   of component priority variables. Few component actually made use of this
   feature.
 - The enumerator interface was updated to be general enough to handle
   future uses of the interface.
 - The code to generate ompi_info output has been moved into the MCA variable
   system. See mca_base_var_dump().

opal: update core and components to mca_base_var system
orte: update core and components to mca_base_var system
ompi: update core and components to mca_base_var system

This commit also modifies the rmaps framework. The following variables were
moved from ppr and lama: rmaps_base_pernode, rmaps_base_n_pernode,
rmaps_base_n_persocket. Both lama and ppr create synonyms for these variables.

4c28c8cbd0 New sm BTL initialization take two. This approach is pretty simple. Instead of
using the modex or RML to share sm initialization information, have node rank 0
create a file containing initialization information in a well-known place. Then
during add_procs, the rest of the node processes requiring sm BTL initialization
will just read from that file to complete their initialization.

0461826a4b Fix bus errors caused by an inadequate amount of space during
opal_shmem_segment_create by testing whether or not the target mount has enough
space to accommodate the shared-memory backing store. Fixes trac:2827. Will work
with Shiqing to add Windows support (if required).

6188d97e1a Getting out of bed this morning was a bad idea... Reverting the sm update once more because it breaks direct launch. Will address this issue and commit the update once it has all been tested. Sorry everyone!

9cef715194 Updates to r25652 -- put this MCA param in the shmem/mmap component.
No need for it to be in the base (we mistakenly thought it was used in
multiple shmem components).

6fbbfd0f7a Gah! r25545 acidentally included ''waaaay'' more stuff than it was
supposed to.  I.e., half-baked/not complete stuff.

This commit backs out all of r25545.  Sorry folks!

7f9ae11faf Per http://www.open-mpi.org/community/lists/users/2011/11/17862.php,
to make MPI_IN_PLACE (and other sentinel Fortran constants) work on OS
X, we need to use the following compiler (linker) flag:

    -Wl,-commons,use_dylibs 

So if we're compiling on OS X, test to see if that flag works with the
compiler.  If so, add it to the wrapper FFLAGS and FCFLAGS (note that
per a future update, we'll only have one Fortran compiler anyway).

Fixes trac:1982.
