info structures used by the btls are not populated.

Several fixes to string handling:
1. strncpy() -> opal_string_copy() (because opal_string_copy()
guarantees to NULL-terminate, and strncpy() does not)
2. Simplify a few places, such as:
* Since opal_string_copy() guarantees to NULL terminate, eliminate
some memsets(), etc.
* Use opal_asprintf() to eliminate multi-step string creation
There's more work that could be done; e.g., this commit doesn't
attempt to clean up any strcpy() usage.

The Open MPI code base assumed that asprintf always behaved like
the FreeBSD variant, where ptr is set to NULL on error. However,
the C standard (and Linux) only guarantee that the return code will
be -1 on error and leave ptr undefined. Rather than fix all the
usage in the code, we use opal_asprintf() wrapper instead, which
guarantees the BSD-like behavior of ptr always being set to NULL.
In addition to being correct, this will fix many, many warnings
in the Open MPI code base.

Get the OMPI rte/pmix component working. This was tested using PRRTE as the RM, configuring OMPI using:
* autogen --no-orte
* with external libevent, external hwloc, and external PMIx master
* configuring PMIx master with the same libevent and hwloc
* execute the application using PRRTE's "prun" launcher, which has the same cmd line as ORTE's mpirun
Note that PMIx master appears to have a bug in the event notification system that caches job termination events. Thus, the first execution runs fine, but subsequent executions cause an "abort" when the OMPI default error handler is invoked upon notification of the prior job's termination. Will work that separately.

(cherry picked from commit 134cca9ac0de092d767999357573a31703f72292)
Cleanup several places where abstraction violations crept into OMPI layer (direct reference of ORTE). Add some missing includes that were exposed by this change.
Note that this compiles, but I haven't tested it for execution yet. Handing it over to Noah Evans for completion
