PMIx_server_register_nspace() is an asynchronous operation, so
the pmix glue wait for it completes before returning.

- New MCA option: opal_stacktrace_output
- Specifies where the stack trace output stream goes.
- Accepts: none, stdout, stderr, file[:filename]
- Default filename 'stacktrace'
- Filename will be `stacktrace.PID`, or if VPID is available,
then the filename will be `stacktrace.VPID.PID`
- Update util/stacktrace to allow for different output avenues
including files. Previously this was hardcoded to 'stderr'.
- Since opal_backtrace_print needs to be signal safe, passing it a
FILE object that actually represents a file stream is difficult. This
is because we cannot open the file in the signal handler using
`fopen` (not safe), but have to use `open` (safe). Additionally, we
cannot use `fdopen` to convert the `int fd` to a `FILE *fh` since it
is also not signal safe.
- I did not want to break the backtrace.h API so I introduced a new
rule (documented in `backtrace.c`) that if the `FILE *file`
argument is `NULL` then look for the `opal_stacktrace_output_fileno`
variable to tell you which file descriptor to use for output.

Since the oob and connections systems do not work the same way they
did in older versions of Open MPI these operations are no longer
necessary. At best they do nothing and at worst they hurt performance
by making us enter the event library more often in opal_progress().

When Java bindings are used, MPI_Init() is not invoked
by the main thread, and this causes some keys being destructed twice.
Reset the per thread values to NULL in order to correctly handle this

* Similar to `orte_map_stddiag_to_stderr` except it redirects `stddiag`
to `stdout` instead of `stderr`.
* Add protection so that the user canot supply both:
- `orte_map_stddiag_to_stderr`
- `orte_map_stddiag_to_stdout`

* The AC_LANG_PROGRAM macro adds the `main()` so it is erroneous
to add it to the test program.
* This was detected with the XL compilers which will fail to
build the program in this situation. The GNU compiler does not
error out or warn, but successfully compiles the program.

Due to the conversion from ssize_t to int we were losing bytes, and
ended up writing outside the receiver buffer. Similarly on the send,
due to the conversion to a lesser type, we could missinterpret the
end of the fragment.
The linux timer code was multiplying the result of the x86 time stamp
counter by 1000000 before dividing by the cpu frequency. This can
cause us to overflow 64 bits if the time stamp counter grows larger
than ~ 1.8e13 (about 8400 seconds after boot). To fix the issue the
units of opal_timer_linux_freq have been changed to MHz.

This commit fixes a deadlock that can occur when the libc version
holds a lock when calling munmap. In this case we could end up calling
free() from vma_tree_delete which would in turn try to obtain the lock
in libc. To avoid the issue put any deleted vma's in a new list on the
vma module and release them on the next call to vma_tree_insert. This
should be safe as this function is not called from the memory hooks.
