Add debug and handle the use-case where someone (a) uses a hostfile while in a managed allocation to sub-allocate runs, and (b) includes the HNP's node in one of those hostfiles.

cmr:v1.7

* Fix issue with duplicate symbol for the initialize hook due to it existing in both libmpi and libopen-pal by removing the one for libopen-pal. This won't work if we eventually need registration caching in opal/orte, but I'm hoping that by that point, OFED will have gotten off its butt and properly integrated ummunotify into the verbs layer so that this code can go away.

At the same time, fix a minor issue where the init hook was being called twice, once by the libc malloc and once by our malloc by removing the call from our malloc.

Remove debug

Fixes #3538: Move r28184 to v1.7 branch

---svn-pre-commit-ignore-below---

r28184 [[BR]]
Clean out the cruft leftover from the use_common_ports experiment

cmr:v1.7

Fix CID 968581: ensure that the string read from the socket is always
\0-terminated so that strlen() and strstr() can be used without fear.
Also fix some insignificant mem leaks (which is somewhat moot, because
as soon as we leave those error conditions, the process will be
terminating, but what the heck, might as well fix these while I was in
the file for the \0-termination issue...).

Changes to OTF:
- fixed even more Coverity warnings

Changes to OTF:
- general: Fixed several Coverity warnings
- otfprofile: Do not show helptext if '-V' given
- otfinfo: Fixed counting of collective operations and markers

Fix CID 741328: remove some dead code

Fix CID 752007: missing break statements.

Avoid double-release in error path
