Joshua Hursey 6d98559be9 stacktrace: Add flexibility in stacktrace ouptut
- 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.
