component member by name.

9cd955badf opal: fix multiple bugs in MCA and opal
This commit fixes the following bugs:

 - opal_output_finalize did not properly set internal state. This
   caused problems when calling the sequence opal_output_init (),
   opal_output_finalize (), opal_output_init ().

 - opal_info support called mca_base_open () but never called the
   matching mca_base_close (). mca_base_open () and mca_base_close ()
   have been updated to use a open count instead of an open flag to
   allow mca_base_open to be called through multiple paths (as may be
   the case when MPI_T is in use).

 - orte_info support did not register opal variables. This can cause
   orte-info to not return opal variables.

 - opal_info, orte_info, and ompi_info support have been updated to
   use a register count.

 - When opening the dl framework the reference count was added to
   ensure the framework stuck around. The framework being closed
   prematurely was a bug in the MCA base that has since been
   corrected. The increment (and associated decrement) have been
   removed.

 - dl/dlopen did not set the value of
   mca_dl_dlopen_component.filename_suffixes_mca_storage on each call
   to register. Instead the value was set in the component
   structure. This caused the value to be lost when re-loading the
   component. Fixed by setting the default value in register.

 - Reset shmem framework state on close to avoid returning a stale
   component after reloading opal/shmem.

 - MCA base parameters were not properly deregistered when the MCA
   base was closed.

This commit may fix #374.

b68d66bb9b MCA: Add the project/project version to the MCA base component
This commit adds support for project_framework_component_* parameter
matching. This is the first step in allowing the same framework name
in multiple projects. This change also bumps the MCA component version
to 2.1.0.

All master frameworks have been updated to use the new component
versioning macro. An mca.h has been added to each project to add a
project specific versioning macro of the form
PROJECT_MCA_VERSION_2_1_0.

65a0e041ac dl: need to use LIBADD, not LIBS
When we use LIBADD for static libraries, the dependent libraries get
propagated properly.  For example, the dl/dlopen component will almost
certainly require the -ldl library; when using LIBS, that doesn't get
propagated elsewhere in the tree, but when using LIBADD, it does
(e.g., when linking opal_wrapper_compiler).

8fef4e865f dl dlopen: fix use-after-free
Re-structure the loop looking for duplicates a little so that we only
have a single free of the string that happens regardless of whether we
found a duplicate or not.

7d340c0c26 dlopen: simple dl component based on POSIX dlopen
Works on systems with dlopen (e.g., Linux and OS X).  It requires
dlfcn.h and libdl, which many systems have installed by default.

e81c070ef0 dl framework: new dynamic loader framework
Embedding libltdl without the use of Libtool bootstrapping has
proven... difficult.  Instead, create a new simple "dl" framework.  It
only provides 4 functions:

- open a DSO (very similar to lt_dlopenadvise())
- lookup a symbol in a previously-opened DSO (very similar to lt_dlsym())
- close a previously-opened DSO (very similar to lt_dlclose())
- iterate over all files in a directory (very similar to ld_dlforeachfile())

There will be follow-on commits with a simple dlopen-based component
(nowhere near as complete/functional as libltdl, but good enough for
Linux and OS X), and a libltdl-based component for all other
platforms.

The intent is that the dlopen-based component can be built by default
in almost all cases.  But if libltdl is available, that component will
be built.  End result: we still get DSO-based functionality by default
in (almost?) all cases.  Without embedding libltdl.  Which is what we
want.
