Allow someone to specify the "pe=N" modifier to a mapping policy when N=1. This equates to just "bind-to core", but helps people who use a script to set the PE policy. Fix a bug where setting the binding policy left a lingering "if-supported" flag that shouldn't be there.

Do not use opal_output_verbose inside O(n) loops. This was causing us
to make O(n) calls to snprintf which was greatly slowing launch at
scale.

This commit adds a new base enumerator type for variables that take of
the values -1, 0, and 1. These values are mapped to the strings auto,
false, true. This commit updates the mpi_leave_pinned MCA variable to
use the new enumerator.

It's possible that we can have zlib.h but still not have zlib support.
Use the correct macro to protect the usage of calling zlib functions.
This fixes 32-bit MTT builds at Cisco (e.g.,

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

so adjust the pmix/ext11 glue accordingly.

- 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.
