This function is only used in ompi_spc.c and is hence declared as static.
Remove its prototype from the header file in order to silence compiler warnings who will typically consider ompi_spc_get_count() as a declared but not defined function.

The PMIx support for "instant on" remains experimental, so disable it by default. Provide an MCA param and corresponding command line option to enable it at runtime.

Fix CID 1435996: use the proper % type to render the size.
Also use opal_output(), not fprintf(). For debug builds, abort
without dumping core (dumping core is very unfriendly when running
thousands of automated tests) -- the stderr output is sufficient to
find the coding error. For non-debug builds, truncate the key and
emit a warning that it almost certainly will not work properly.

This commit add support for scalable endpoint to enhance multithreaded
application performance. The BTL will detect the support from ofi
provider and will fallback to normal usage of scalable endpoint is not
supported.
NEW MCA parameters:
- mca_btl_ofi_disable_sep: force the btl to not use scalable endpoint.
- mca_btl_ofi_num_contexts_per_module: number of communication context
to create (should be the same as number of thread).

configure: add checks for `__thread` on top of current check for `_Thread_local` and define OPAL_HAVE_THREAD_LOCAL if the compiler support TLS.
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.
