Added `opal_thread_local` keyword to unify the definition.

This code is the implementation of Software-base Performance Counters as described in the paper 'Using Software-Base Performance Counters to Expose Low-Level Open MPI Performance Information' in EuroMPI/USA '17 (http://icl.cs.utk.edu/news_pub/submissions/software-performance-counters.pdf). More practical usage information can be found here: https://github.com/davideberius/ompi/wiki/How-to-Use-Software-Based-Performance-Counters-(SPCs)-in-Open-MPI.
All software events functions are put in macros that become no-ops when SOFTWARE_EVENTS_ENABLE is not defined. The internal timer units have been changed to cycles to avoid division operations which was a large source of overhead as discussed in the paper. Added a --with-spc configure option to enable SPCs in the Open MPI build. This defines SOFTWARE_EVENTS_ENABLE. Added an MCA parameter, mpi_spc_enable, for turning on specific counters. Added an MCA parameter, mpi_spc_dump_enabled, for turning on and off dumping SPC counters in MPI_Finalize. Added an SPC test and example.

FI_MR_UNSPEC is not supposed to be used beyond ofi version 1.5. This
commit replaces FI_MR_UNSPEC with the new FI_MR_BASIC mode bits
(FI_MR_PROV_KEY | FI_MR_ALLOCATED | FI_MR_VIRT_ADDR).
The btl functionality remains the same.

in case the user opened a file using the DELETE_ON_CLOSE flag,
return the error code generated in the delete operation.
Note, that this is however just a partial fix to the e_close_1 test
from the ibm testsuite, since the object destructor that triggers
the file_close function does not have a mechanism right now to recognize
and return an error code.

We introduced a new mca_vulcan parameter that specify the I/O synchronization
type (Async/sync I/O) applied within the collective write operation.
The user can explicitly choose to use async or sync write operation or make
the choice automatically made.

If a subroutine of the Fortran `use-mpi-f08` binding in an MPI extension
have a `LOGICAL` parameter and no `TYPE(MPI_Status)` parameter,
it needs to use the `mpi_ext` module and call its corresponding subroutine
in the `mpif-h` directory, as explained in
`ompi/mpi/fortran/use-mpi-f08/mpi-f-interfaces-bind.h`.
However, as shown in the figure below, the required directories are dependent
on each other, and "Can't open module file" error occurs at build time.
ompi/mpiext/{extension name}/use-mpi-f08
A |
| |
| V
ompi/mpi/fortran/use-mpi-f08 <--- ompi/mpi/fortran/mpiext (mpi_ext.mod)
In order to solve this problem, change the configuration and the build order.
- divide Fortran extension directory (`ompi/mpi/fortran/mpiext`)
into the directories for `use-mpi` and for `use-mpi-08`
- `ompi/mpi/fortran/mpiext-use-mpi` : for `use-mpi` (mpi_ext.mod)
- `ompi/mpi/fortran/mpiext-use-mpi-f08` : for `use-mpi-08` (mpi_f08_ext.mod)
- change to the following build order about Fortran `use-mpi` and
`use-mpi-f08` bindings in `ompi`
1. mpi_ext bindings of MPI extensions (`mpiext/{extension name}/use-mpi` directory)
2. Fortran use-mpi (`mpi/fortran/use-mpi-[ignore-]tkr` directory)
3. Fortran extension for use-mpi (`mpi/fortran/mpiext-use-mpi` directory)
4. Fortran use-mpi-f08 modules only (`mpi/fortran/use-mpi-f08/mod` directory)
5. mpi_f08_ext bindings of MPI extensions (`mpiext/{extension name}/use-mpi-f08` directory)
6. Fortran use-mpi-f08 (`mpi/fortran/use-mpi-f08` directory)
7. Fortran extension for use-mpi-f08 (`mpi/fortran/mpiext-use-mpi-f08` directory)
